with _mesa_create_context, fixing another leak.

9def08ad3d Fix up alpha buffer handling for Windows.
- add two new Pixel Format Descriptors that do not have alpha bits to
mirror the two that do.
- add logic to wglChoosePixelFormat to match PFD's with respect to alpha.
- Create/clear software alpha buffer as required.
Now a wgl or GLUT program can control the creation of a software alpha
buffer via the PFD or GLUT parms, respectively.

a4f3130a7f Lots of changes related to framebuffer/window buffer resizing. Basically,
instead of passing a GLcontext* to ResizeBuffers(), pass a GLframebuffer*.
The idea is that a window can be resized without it being bound to a rendering
context.  This makes for a nice clean-up in the XFree86 server-side GLX code.
Renamed ctx->Driver.ResizeBuffersMESA() to ctx->Driver.ResizeBuffers().

# Make a shared library.
# Basically do a switch/case depending on the OS and make a shared
# lib conforming to that OS.
# Usage:
# mklib [options] objects ...
# Options:
# -o LIBRARY specifies the name of resulting library ("GL" for example)
# -major N specifies major version number (default is 1)
# -minor N specifies minor version number (default is 0)
# -patch N specifies patch version number (default is 0)
# -lLIBRARY specifies a dependency on LIBRARY
# -LDIR search in DIR for library dependencies
# -cplusplus link with C++ runtime
# -static make a static library (default is dynamic/shared)
# -install DIR move resulting library files to DIR
# -arch ARCH override using `uname` to determine architecture
# -archopt OPT specify an extra achitecture-specific option OPT
#
# The library name should just be "GL" or "GLU", etc. The 'lib' prefix
# will be added here if needed, as well as the ".so" or ".a" suffix, etc.
#
# objects should be: foo.o bar.o etc.o

OpenGL 1.4 is required
The extension is written against the OpenGL 1.4 specification.
ARB_vertex_program or ARB_fragment_program or NV_vertex_program
or NV_fragment_program is required.
Overview
The extension provides facilities for implementing debuggers for
vertex and fragment programs.
The concept is that vertex and fragment program debuggers will be
implemented outside of the GL as a utility package. This extension
only provides the minimal hooks required to implement a debugger.
There are facilities to do the following:
1. Have the GL call a user-specified function prior to executing
each vertex or fragment instruction.
2. Query the current program string's execution position.
3. Query the current values of intermediate program values.
The main feature is the ProgramCallbackMESA function. It allows the
user to register a callback function with the GL. The callback will
be called prior to executing each vertex or fragment program instruction.
From within the callback, the user may issue Get* commands to
query current GL state. The GetProgramRegisterfvMESA function allows
current program values to be queried (such as temporaries, input
attributes, and result registers).
There are flags for enabling/disabling the program callbacks.
The current execution position (as an offset from the start of the
program string) can be queried with
GetIntegerv(GL_FRAGMENT_PROGRAM_POSITION_MESA, &pos) or
GetIntegerv(GL_VERTEX_PROGRAM_POSITION_MESA, &pos).
IP Status
None
Issues
1. Is this the right model for a debugger?
It seems prudent to minimize the scope of this extension and leave
it up to the developer (or developer community) to write debuggers
that layer on top of this extension.
If the debugger were fully implemented within the GL it's not
clear how terminal and GUI-based interfaces would work, for
example.
2. There aren't any other extensions that register callbacks with
the GL. Isn't there another solution?
If we want to be able to single-step through vertex/fragment
programs I don't see another way to do it.
3. How do we prevent the user from doing something crazy in the
callback function, like trying to call glBegin (leading to
recursion)?
The rule is that the callback function can only issue glGet*()
functions and no other GL commands. It could be difficult to
enforce this, however. Therefore, calling any non-get GL
command from within the callback will result in undefined
results.
4. Is this extension amenable to hardware implementation?
Hopefully, but if not, the GL implementation will have to fall
back to a software path when debugging. This may be acceptable
for debugging.
5. What's the <data> parameter to ProgramCallbackMESA for?
It's a common programming practice to associate a user-supplied
value with callback functions.
6. Debuggers often allow one to modify intermediate program values,
then continue. Does this extension support that?
No.

Additions to Chapter 5 of the OpenGL 1.4 Specification (Special Functions)
In section 5.4 "Display Lists", page 202, add the following command
to the list of those that are not compiled into display lists:
ProgramCallbackMESA.
Add a new section 5.7 "Callback Functions"
The function
void ProgramCallbackMESA(enum target, programcallbackMESA callback,
void *data)
registers a user-defined callback function with the GL. <target>
may be FRAGMENT_PROGRAM_ARB or VERTEX_PROGRAM_ARB. The enabled
callback functions registered with these targets will be called
prior to executing each instruction in the current fragment or
vertex program, respectively. The callbacks are enabled and
disabled by calling Enable or Disable with <cap>
FRAGMENT_PROGRAM_ARB or VERTEX_PROGRAM_ARB.
The callback function's signature must match the typedef
typedef void (*programcallbackMESA)(enum target, void *data)
When the callback function is called, <target> will either be
FRAGMENT_PROGRAM_ARB or VERTEX_PROGRAM_ARB to indicate which
program is currently executing and <data> will be the value
specified when ProgramCallbackMESA was called.
From within the callback function, only the following GL commands
may be called:
GetBooleanv
GetDoublev
GetFloatv
GetIntegerv
GetProgramLocalParameter
GetProgramEnvParameter
GetProgramRegisterfvMESA
GetProgramivARB
GetProgramStringARB
GetError
Calling any other command from within the callback results in
undefined behaviour.
Additions to Chapter 6 of the OpenGL 1.4 Specification (State and
State Requests)
Add a new section 6.1.3 "Program Value Queries":
The command
void GetProgramRegisterfvMESA(enum target, sizei len,
const ubyte *registerName,
float *v)
Is used to query the value of program variables and registers
during program execution. GetProgramRegisterfvMESA may only be
called from within a callback function registered with
ProgramCallbackMESA.
<registerName> and <len> specify the name a variable, input
attribute, temporary, or result register in the program string.
The current value of the named variable is returned as four
values in <v>. If <name> doesn't exist in the program string,
the error INVALID_OPERATION is generated.
Additions to Appendix A of the OpenGL 1.4 Specification (Invariance)
None.
Additions to the AGL/GLX/WGL Specifications
None.

XXX TBD
Dependencies on NV_vertex_program and NV_fragment_program
If NV_vertex_program and/or NV_fragment_program are supported,
vertex and/or fragment programs defined by those extensions may
be debugged as well. Register queries will use the syntax used
by those extensions (i.e. "v[X]" to query vertex attributes,
"o[X]" for vertex outputs, etc.)
Errors
INVALID_OPERATION is generated if ProgramCallbackMESA is called
between Begin and End.
INVALID_ENUM is generated by ProgramCallbackMESA if <target> is not
a supported vertex or fragment program type.
Note: INVALID_OPERAION IS NOT generated by GetProgramRegisterfvMESA,
GetBooleanv, GetDoublev, GetFloatv, or GetIntegerv if called between
Begin and End when a vertex or fragment program is currently executing.
INVALID_ENUM is generated by ProgramCallbackMESA,
GetProgramRegisterfvMESA if <target> is not a program target supported
by ARB_vertex_program, ARB_fragment_program (or NV_vertex_program or
NV_fragment_program).
INVALID_VALUE is generated by GetProgramRegisterfvMESA if <registerName>
does not name a known program register or variable.
INVALID_OPERATION is generated by GetProgramRegisterfvMESA when a
register query is attempted for a program target that's not currently
being executed.

Additions to the GLX 1.3 Specification
[Add the following to Section 3.3.10 of the GLX Specification (Double
Buffering)]
glXSwapIntervalMESA specifies the minimum number of video frame periods
per buffer swap. (e.g. a value of two means that the color buffers
will be swapped at most every other video frame.) A return value
of zero indicates success; otherwise an error occurred. The interval
takes effect when glXSwapBuffers is first called subsequent to the
glXSwapIntervalMESA call.
A video frame period is the time required by the monitor to display a
full frame of video data. In the case of an interlaced monitor,
this is typically the time required to display both the even and odd
fields of a frame of video data.
If <interval> is set to a value of 0, buffer swaps are not synchron-
ized to a video frame. The <interval> value is silently clamped to
the maximum implementation-dependent value supported before being
stored.
The swap interval is not part of the render context state. It cannot
be pushed or popped. The current swap interval for the window
associated with the current context can be obtained by calling
glXGetSwapIntervalMESA. The default swap interval is 0.
On XFree86, setting the environment variable LIBGL_THROTTLE_REFRESH sets
the swap interval to 1.
Errors
glXSwapIntervalMESA returns GLX_BAD_VALUE if parameter <interval> is
less than zero.
glXSwapIntervalMESA returns GLX_BAD_CONTEXT if there is no current
GLXContext.
GLX Protocol
None. This extension only extends to direct rendering contexts.

GLX_SGI_swap_control affects the definition of this extension.
GLX_MESA_swap_control affects the definition of this extension.
GLX_OML_sync_control affects the definition of this extension.
Based on WGL_I3D_swap_frame_usage version 1.3.
Overview
This extension allows an application to deterine what portion of the
swap period has elapsed since the last swap operation completed. The
"usage" value is a floating point value on the range [0,max] which is
calculated as follows:
td
percent = ----
tf
where td is the time measured from the last completed buffer swap (or
call to enable the statistic) to when the next buffer swap completes, tf
is the entire time for a frame which may be multiple screen refreshes
depending on the swap interval as set by the GLX_SGI_swap_control or
GLX_OML_sync_control extensions.
The value, percent, indicates the amount of time spent between the
completion of the two swaps. If the value is in the range [0,1], the
buffer swap occurred within the time period required to maintain a
constant frame rate. If the value is in the range (1,max], a constant
frame rate was not achieved. The value indicates the number of frames
required to draw.
This definition of "percent" differs slightly from
WGL_I3D_swap_frame_usage. In WGL_I3D_swap_frame_usage, the measurement
is taken from the completion of one swap to the issuance of the next.
This representation may not be as useful as measuring between
completions, as a significant amount of time may pass between the
issuance of a swap and the swap actually occuring.
There is also a mechanism to determine whether a frame swap was
missed.

Additions to the GLX 1.3 Specification
The frame usage is measured as the percentage of the swap period elapsed
between two buffer-swap operations being commited. In unextened GLX the
swap period is the vertical refresh time. If SGI_swap_control or
MESA_swap_control are supported, the swap period is the vertical refresh
time multiplied by the swap interval (or one if the swap interval is set
to zero).
If OML_sync_control is supported, the swap period is the vertical
refresh time multiplied by the divisor parameter to
glXSwapBuffersMscOML. The frame usage in this case is less than 1.0 if
the swap is commited before target_msc, and is greater than or equal to
1.0 otherwise. The actual usage value is based on the divisor and is
never less than 0.0.
int glXBeginFrameTrackingMESA(Display *dpy,
GLXDrawable drawable,
float *usage)
glXGetFrameUsageMESA returns a floating-point value in <usage>
that represents the current swap usage, as defined above.
Missed frame swaps can be tracked by calling the following function:
int glXBeginFrameTrackingMESA(Display *dpy,
GLXDrawable drawable)
glXBeginFrameTrackingMESA resets a "missed frame" count and
synchronizes with the next frame vertical sync before it returns.
If a swap is missed based in the rate control specified by the
<interval> set by glXSwapIntervalSGI or the default swap of once
per frame, the missed frame count is incremented.
The current missed frame count and total number of swaps since
the last call to glXBeginFrameTrackingMESA can be obtained by
callling the following function:
int glXQueryFrameTrackingMESA(Display *dpy,
GLXDrawable drawable,
int64_t *swapCount,
int64_t *missedFrames,
float *lastMissedUsage)
The location pointed to by <swapCount> will be updated with the
number of swaps that have been commited. This value may not match the
number of swaps that have been requested since swaps may be
queued by the implementation. This function can be called at any
time and does not synchronize to vertical blank.
The location pointed to by <missedFrames> will contain the number
swaps that missed the specified frame. The frame usage for the
last missed frame is returned in the location pointed to by
<lastMissedUsage>.
Frame tracking is disabled by calling the function
int glXEndFrameTrackingMESA(Display *dpy,
GLXDrawable drawable)
This function will not return until all swaps have occurred. The
application can call glXQueryFrameTrackingMESA for a final swap and
missed frame count.
If these functions are succesful, zero is returned. If the context
associated with dpy and drawable is not a direct context,
GLX_BAD_CONTEXT is returned.
Errors
If the function succeeds, zero is returned. If the function
fails, one of the following error codes is returned:
GLX_BAD_CONTEXT The current rendering context is not a direct
context.
GLX Protocol
None. This extension only extends to direct rendering contexts.

<h1>1. Introduction</h1>
<p>The Mini GLX interface facilitates OpenGL rendering on embedded
devices. The interface is a subset of the GLX interface, plus a minimal
set of Xlib-like functions.</p>
<p>Programs written to the Mini GLX specification should run unchanged
on systems with the X Window System and the GLX extension. The intention
is to allow flexibility for prototyping and testing.</p>
<p>This document serves as both the reference guide and programming
guide for Mini GLX.<br>
<br>
</p>
<h1>2. Mini GLX Concepts</h1>
<p>The OpenGL specification does not describe how OpenGL rendering
contexts and drawing surfaces (i.e. the frame buffer) are created and
managed. Rather, this is handled by an OpenGL window system interface,
such as Mini GLX.</p>
<p>There are three main datatypes or resources managed by Mini GLX. The
resources and their corresponding GLX or Xlib data types are:</p>
<table cellspacing="10" align="center">
<tbody>
<tr>
<td><u>Resource</u></td>
<td><u>Data type</u></td>
</tr>
<tr>
<td>pixel formats</td>
<td>X Visual and XVisualInfo</td>
</tr>
<tr>
<td>drawing surfaces</td>
<td>X Window or GLXDrawable</td>
</tr>
<tr>
<td>rendering contexts</td>
<td>GLXContext</td>
</tr>
</tbody>
</table>
<p>Pixel formats or X Visuals describe the per-pixel attributes of the
frame buffer. For example, bits per color component, Z buffer size,
stencil size, TrueColor vs PseudoColor, etc.</p>
<p>Drawing surfaces or X Windows typically describe a spatial
allocation of the frame buffer (i.e. the position and size of a
rectangular region of pixels). Since MiniGLX doesn't really support a
window system, the window is effectively the entire frame buffer.</p>
<p>A rendering context represents the current OpenGL state such as
current drawing color, line width, blending mode, texture parameters,
etc. Several rendering contexts can be created but only one can be in
use at any given time.</p>
<p>The Mini GLX interface provides all the functions needed for
choosing pixel formats, create drawing surfaces, creating rendering
contexts and binding rendering contexts to drawing surfaces.<br>
<br>
</p>
<h1>3. Using Mini GLX</h1>
<p>To use the Mini GLX interface in your application, include the
GL/miniglx.h header file at compile time:</p>
<blockquote><code> #include &lt;GL/miniglx.h&gt;<br>
</code></blockquote>
<code></code>Applications should link with libGL.so (i.e. <code>gcc
myprogram.o -lGL -o myprogram</code>). &nbsp;libGL.so implements the
MiniGLX API functions and, in turn, loads a hardware-specific device
driver (such as <code>radeon_dri.so</code>) at runtime. &nbsp;The
environment variable <code>LIBGL_DRIVERS_PATH</code> should name the
directory where these modules are located.<br>
<br>
Prior to running a MiniGXL application, the following kernel modules
must be installed:<br>
<br>
<div style="margin-left: 40px;"> agpgart.o<br>
radeonfb.o &nbsp;(assuming Radeon hardware)<br>
radeon.o &nbsp;(assuming Radeon hardware)<br>
</div>
<code></code> <br>
Finally, MiniGLX reads a configuration file (by default,<code>
/etc/miniglx.conf</code>) to determine basic configuration information.
&nbsp;The configuration file may also be located in the directory
specified by the <code>MINIGLX_CONF</code> environment variable).<br>
<br>
The remainder of this section describes the MiniGLX API functions.<br>
<br>
<h2>3.1 Initialization</h2>
<p>The XOpenDisplay function is used to initialize the graphics system:</p>
<blockquote>
<pre>Display *XOpenDisplay(const char *displayname)<br></pre>
</blockquote>
<p>The <code>displayName</code> parameter is currently ignored in Mini
GLX. It is recommended that <code>NULL</code> be passed as the<code>displayName</code>
parameter.</p>
<p>If XOpenDisplay is able to initialize the graphics system a pointer
to a Display will be returned. Otherwise, NULL will be returned.</p>
<h2>3.2 Choosing a Visual</h2>
<p>A visual (i.e. pixel format) must be chosen before a drawing surface
or rendering context can be created. This is done with the
glXChooseVisual function:</p>
<blockquote>
<pre>XVisualInfo *glXChooseVisual(Display *dpy, int screen, const int *attribList)<br></pre>
</blockquote>
<p><code>dpy</code> is a pointer to the display returned by
XOpenDisplay. </p>
<p><code>screen</code> is currently ignored by Mini GLX and should be
zero. </p>
<p><code>attribList</code> is a list of GLX attributes which describe
the desired pixel format. It is terminated by the token <code>None</code>.
The attributes are as follows:</p>
<blockquote>
<dl>
<dt><code>GLX_USE_GL</code></dt>
<dd>This attribute should always be present in order to maintain
compatibility with GLX.</dd>
<dt><code>GLX_RGBA</code></dt>
<dd>If present, only RGBA pixel formats will be considered.
Otherwise, only color index formats are considered.</dd>
<dt><code>GLX_DOUBLEBUFFER</code></dt>
<dd>if present, only double-buffered pixel formats will be chosen.</dd>
<dt><code>GLX_RED_SIZE n</code></dt>
<dd>Must be followed by a non-negative integer indicating the
minimum number of bits per red pixel component that is acceptable.</dd>
<dt><code>GLX_GREEN_SIZE n</code></dt>
<dd>Must be followed by a non-negative integer indicating the
minimum number of bits per green pixel component that is acceptable.</dd>
<dt><code>GLX_BLUE_SIZE n</code></dt>
<dd>Must be followed by a non-negative integer indicating the
minimum number of bits per blue pixel component that is acceptable.</dd>
<dt><code>GLX_ALPHA_SIZE n</code></dt>
<dd>Must be followed by a non-negative integer indicating the
minimum number of bits per alpha pixel component that is acceptable.</dd>
<dt><code>GLX_STENCIL_SIZE n</code></dt>
<dd>Must be followed by a non-negative integer indicating the
minimum number of bits per stencil value that is acceptable.</dd>
<dt><code>None</code></dt>
<dd>This token is used to terminate the attribute list.</dd>
</dl>
</blockquote>
<p>glXChooseVisual will return a pointer to an XVisualInfo object which
most closely matches the requirements of the attribute list. If there
is no visual which matches the request, NULL will be returned.</p>
<p>Note that visuals with accumulation buffers and depth buffers are
not available.<br>
<br>
</p>
<h2>3.3 Creating a Drawing Surface</h2>
<p>Drawing surfaces are created as X windows. &nbsp;For Mini GLX,
windows are <i>full-screen</i>; they cover the entire frame buffer.
&nbsp;Also, Mini GLX imposes a limit of one window. A second window
cannot be created until the first one is destroyed.</p>
<h3>3.3.1 Window Creation</h3>
<p>The XCreateWindow function is used to create a drawing surface:</p>
<blockquote>
<pre>Window XCreateWindow( Display *display,<br> Window parent,<br> int x, int y,<br> unsigned int width, unsigned int height,<br> unsigned int borderWidth,<br> int depth,<br> unsigned int class,<br> Visual *visual,<br> unsigned long valuemask,<br> XSetWindowAttributes *attributes )<br></pre>
</blockquote>
<p>The parameters are as follows:</p>
<blockquote>
<dl>
<dt><code>display</code></dt>
<dd>A Display pointer, as returned by XOpenDisplay.</dd>
<dt><code>parent</code></dt>
<dd>The parent window for the new window. For Mini GLX, this
should be<code>RootWindow(dpy, 0)</code>.</dd>
<dt><code>x, y</code></dt>
<dd>The position of the window. For Mini GLX, both values should
be zero.</dd>
<dt><code>width, height</code></dt>
<dd>The size of the window. For Mini GLX, this specifies the
desired screen size such as 1024, 768 or 1280, 1024.</dd>
<dt><code>borderWidth</code></dt>
<dd>This parameter should be zero.</dd>
<dt><code>depth</code></dt>
<dd>The pixel depth for the window. For Mini GLX this should be
the depth found in the XVisualInfo object returned by <code>glxChooseVisual</code>.</dd>
<dt><code>class</code></dt>
<dd>The window class. For Mini GLX this value should be <code>InputOutput</code>.</dd>
<dt><code>visual</code></dt>
<dd>This parameter should be the <code>visual</code> field of the <code>XVisualInfo</code>
object returned by <code>glxChooseVisual</code>.</dd>
<dt><code>valuemask</code></dt>
<dd>This parameter indicates which fields of the <code>XSetWindowAttributes</code>
are to be used. For Mini GLX this is typically the bitmask<code>CWBackPixel
| CWBorderPixel | CWColormap</code>.</dd>
<dt><code>attributes</code></dt>
<dd>Initial window attributes. Of the fields in the <code>XSetWindowAttributes</code>
structure, the<code>background_pixel</code>, <code>border_pixel</code>
and <code>colormap</code> fields should be set. &nbsp;See the discussion
below regarding colormaps.</dd>
</dl>
</blockquote>
<p><code>XCreateWindow</code> will return a window handle if it succeeds
or zero if it fails.</p>
<h3>3.3.2 Window Mapping</h3>
<p>To display the window the XMapWindow function must be called:</p>
<blockquote>
<pre>void XMapWindow(Display *dpy, Window w)</pre>
</blockquote>
<p>This function does nothing in Mini GLX but is required for Xlib/GLX
compatibility</p>
<h3>3.3.3 Colormaps<br>
</h3>
<p>Xlib requires specification of a colormap when creating a window.
&nbsp;For purposes of interoperability, Mini GLX requires this as well,
though the colormap is not actually used. &nbsp;The XCreateColormap
function is used to create a colormap:</p>
<blockquote><code>Colormap XCreateColormap(Display *dpy, Window window,
Visual *visual, int alloc)</code><br>
<code></code></blockquote>
<p>The parameters are as follows:<br>
</p>
<blockquote>
<dl>
<dt><code>dpy</code></dt>
<dd>The display handle as returned by XOpenDisplay.</dd>
<dt><code>window</code></dt>
<dd> This parameter is ignored by Mini GLX but should be the value
returned by the <code>RootWindow(dpy, 0)</code> macro.<br>
</dd>
<dt><code>visual</code></dt>
<dd>This parameter is ignored by Mini GLX but should be the visual
field of the XVisualInfo object returned by glXChooseVisual. </dd>
<dt><code>alloc</code></dt>
<dd>This parameter is ignored by Mini GLX but should be set to <code>AllocNone</code>.</dd>
</dl>
</blockquote>
<br>
<h2>3.4 Creating a Rendering Context</h2>
<p>An OpenGL rendering context is created with the <code>glXCreateContext</code>
function:</p>
<blockquote>
<pre>GLXContext glXCreateContext(Display *dpy, XVisualInfo *visInfo, GLXContext shareList, Bool direct)<br></pre>
</blockquote>
<p>The parameters are as follows:</p>
<blockquote>
<dl>
<dt><code>dpy</code></dt>
<dd>The display handle as returned by XOpenDisplay.</dd>
<dt><code>visInfo</code></dt>
<dd>The visual as returned by glXChooseVisual.</dd>
<dt><code>shareList</code></dt>
<dd>If non-zero, texture objects and display lists are shared with
the named rendering context. If zero, texture objects and display lists
will (initially) be private to this context. They may be shared when a
subsequent context is created.</dd>
<dt><code>direct</code></dt>
<dd>Specifies whether direct or indirect rendering is desired. For
Mini GLX this value is ignored but it should be set to <code>True</code>.</dd>
</dl>
</blockquote>
<p><code>glXCreateContext</code> will return a GLXContext handle if it
succeeds or zero if it fails due to invalid parameter or insufficient
resources.<br>
<br>
</p>
<h2>3.5 Binding a Rendering Context</h2>
<p>The final step before beginning OpenGL rendering is to bind (i.e.
activate) a rendering context and drawing surface with the
glXMakeCurrent function:</p>
<blockquote>
<pre>Bool glXMakeCurrent(Display *dpy, GLXDrawable drawable, GLXContext ctx)<br></pre>
</blockquote>
<p>The parameters are as follows:</p>
<blockquote>
<dl>
<dt><code>dpy</code></dt>
<dd>The display handle, as returned by XOpenDisplay.</dd>
<dt><code>drawable</code></dt>
<dd>The window or drawable to bind to the rendering context. This
should be the value returned by XCreateWindow.</dd>
<dt><code>ctx</code></dt>
<dd>The rendering context to bind, as returned by glXCreateContext.</dd>
</dl>
</blockquote>
<p>If glXMakeCurrent succeeds True is returned. Otherwise False is
returned to indicate an invalid display, window or context parameter.</p>
<p>After the rendering context has been bound to the drawing surface
OpenGL rendering can begin.</p>
<p>The current rendering context may be unbound by calling
glXMakeCurrent with the window and context parameters set to zero.</p>
<p>An application may create any number of rendering contexts and bind
them as needed. Note that binding a rendering context is generally not a
light-weight operation. &nbsp;Most simple OpenGL applications create
only one rendering context.<br>
<br>
</p>
<h2>3.6 Color Buffer Swapping</h2>
<p>A double buffered window has two color buffers: a front buffer and a
back buffer. Normally, rendering is directed to the back buffer while
the front buffer is displayed. When rendering of a frame is finished
the front and back buffers are swapped to provide the illusion of
instanteous screen updates.</p>
<p>The color buffers for a particular window (i.e. drawable) may be
swapped with the glXSwapBuffers command:</p>
<blockquote>
<pre>void glXSwapBuffers(Display *dpy, GLXDrawable drawable)<br></pre>
</blockquote>
Any pending rendering commands will be completed before the buffer swap
takes place.<br>
<br>
Calling glXSwapBuffers on a window which is single-buffered has no
effect.<br>
<br>
<h2>3.7 Releasing Resources</h2>
<h3>3.7.1 Releasing Rendering Contexts</h3>
<p>A rendering context may be destroyed by calling glXDestroyContext:</p>
<blockquote>
<pre>void glXDestroyContext(Display *dpy, GLXContext ctx)<br></pre>
</blockquote>
<h3>3.7.2 Releasing Windows</h3>
<p>A window may be destroyed by calling XDestroyWindow:</p>
<blockquote>
<pre>void XDestroyWindow(Display *dpy, Window window)<br></pre>
</blockquote>
<h3>3.7.3 Releasing Visuals</h3>
<p>An XVisualInfo object may be freed by calling XFree:</p>
<blockquote>
<pre>void XFree(void *data)<br></pre>
</blockquote>
<h3>3.7.4 Releasing Colormaps</h3>
<p>A colormap may be freed by calling XFreeColormap:</p>
<blockquote>
<pre>void XFreeColormap(Display *dpy, Colormap colormap)<br></pre>
</blockquote>
<h3>3.7.4 Releasing Display Resources</h3>
<p>When the application is about to exit, the resources associated with
the graphics system can be released by calling XCloseDisplay:</p>
<blockquote>
<pre>void XCloseDisplay(Display *dpy)<br></pre>
</blockquote>
<p>The display handle becomes invalid at this point.<br>
<br>
</p>
<h2>3.8 Query Functions</h2>
<h3>3.8.1 Querying Available Visuals</h3>
A list of all available visuals can be obtained with the XGetVisualInfo
function:<br>
<br>
<div style="margin-left: 40px;"><code>XVisualInfo
*XGetVisualInfo(Display *dpy, long vinfo_mask, XVisualInfo
*vinfo_template, int *nitems_return)<br>
</code></div>
<br>
The parameters are as follows:<br>
<blockquote>
<dl>
<dt><code>dpy</code></dt>
<dd>The display handle, as returned by XOpenDisplay.</dd>
<dt><code>vinfo_mask</code></dt>
<dd>A bitmask indicating which fields of the vinfo_template are to
be matched. &nbsp;The value must be VisualScreenMask.</dd>
<dt><code>vinfo_template</code></dt>
<dd>A template whose fields indicate which visual attributes must
be matched by the results. &nbsp;The screen field of this structure must
be zero.</dd>
<dt><code>nitems_return</code></dt>
<dd>Returns the number of visuals returned. </dd>
</dl>
</blockquote>
The return value is the address of an array of all available visuals.<br>
<br>
An example of using XGetVisualInfo to get all available visuals follows:<br>
<br>
<div style="margin-left: 40px;"><code>XVisualInfo visTemplate, *results;</code><br>
<code>int numVisuals;</code><br>
<code>Display *dpy = XOpenDisplay(NULL);</code><br>
<code>visTemplate.screen = 0;</code><br>
<code>results = XGetVisualInfo(dpy, VisualScreenMask, &amp;visTemplate,
&amp;numVisuals);</code><br>
<code></code></div>
<br>
<h3>3.8.2 Querying Visual Attributes</h3>
<p>The GLX attributes of an X visual may be queried with the
glXGetConfig function:</p>
<blockquote>
<pre>int glXGetConfig(Display *dpy, XVisualInfo *vis, int attribute, int *value)<br></pre>
</blockquote>
<p>The parameters are as follows:</p>
<blockquote>
<dl>
<dt><code>dpy</code></dt>
<dd>The display handle, as returned by XOpenDisplay.</dd>
<dt><code>vis</code></dt>
<dd>The visual, as returned by glXChooseVisual.</dd>
<dt><code>attribute</code></dt>
<dd>The attribute to query. The attributes are listed below.</dd>
<dt><code>value</code></dt>
<dd>Pointer to an integer in which the result of the query will be
stored. </dd>
</dl>
</blockquote>
<p>The return value will be zero if no error occurs.<code>
&nbsp;GLX_INVALID_ATTRIBUTE</code> will be returned if the attribute
parameter is invalid.<code> &nbsp;GLX_BAD_VISUAL</code> will be returned
if the XVisualInfo parameter is invalid.</p>
<p>The following attributes may be queried:</p>
<blockquote>
<dl>
<dt><code>GLX_USE_GL</code></dt>
<dd>The result will be <code>True</code> or <code>False</code> to
indicate if OpenGL rendering is supported with the visual. Mini GLX
always return <code>True</code>.</dd>
<dt><code>GLX_RGBA</code></dt>
<dd>The result will be <code>True</code> for RGBA visuals or <code>False</code>
for color index visuals.</dd>
<dt><code>GLX_DOUBLEBUFFER</code></dt>
<dd>The result will be <code>True</code> if the visual has two
color buffers or <code>False</code> if the visual has one color buffer.</dd>
<dt><code>GLX_RED_SIZE</code></dt>
<dd>The result will be the number of red bits per pixel.</dd>
<dt><code>GLX_GREEN_SIZE</code></dt>
<dd>The result will be the number of green bits per pixel.</dd>
<dt><code>GLX_BLUE_SIZE</code></dt>
<dd>The result will be the number of blue bits per pixel.</dd>
<dt><code>GLX_ALPHA_SIZE</code></dt>
<dd>The result will be the number of alpha bits per pixel.</dd>
<dt><code>GLX_DEPTH_SIZE</code></dt>
<dd>The result will be the number of bits per Z value.</dd>
<dt><code>GLX_STENCIL_SIZE</code></dt>
<dd>The result will be the number of bits per stencil value.<br>
<br>
</dd>
</dl>
</blockquote>
<h3>3.8.3 Querying the Current Rendering Context</h3>
<p>The current rendering context can be queried with
glXGetCurrentContext: </p>
<blockquote>
<pre>GLXContext glXGetCurrentContext(void)<br></pre>
</blockquote>
<p>Zero will be returned if no context is currently bound.<br>
<br>
</p>
<h3>3.8.4 Querying the Current Drawable</h3>
<p>The current drawable (i.e. window or drawing surface) can be queried
with glXGetCurrentDrawable:</p>
<blockquote>
<pre>GLXDrawable glXGetCurrentDrawable(void)<br></pre>
</blockquote>
<p>Zero will be returned if no drawable is currently bound.<br>
<br>
</p>
<h3>3.8.5 Function Address Queries</h3>
<p>The glXGetProcAddress function will return the address of any
available OpenGL or Mini GLX function:</p>
<blockquote>
<pre>void *glXGetProcAddress(const GLubyte *procName)<br></pre>
</blockquote>
<p>If <code>procName</code> is a valid function name, a pointer to that
function will be returned. &nbsp;Otherwise, NULL will be returned.</p>
<p>The purpose of glXGetProcAddress is to facilitate using future
extensions to OpenGL or Mini GLX. If a future version of the library
adds new extension functions they'll be accessible via
glXGetProcAddress. The alternative is to hard-code calls to the new
functions in the application but doing so will prevent linking the
application with older versions of the library.<br>
<br>
</p>
<h2>3.9 Versioning</h2>
The Mini GLX version can be queried at run time with glXQueryVersion:
<blockquote>
<pre>Bool glXQueryVersion(Display *dpy, int *major, int *minor)<br></pre>
</blockquote>
<p><code>major</code> will be set to the major version number and<code>minor</code>
will be set to the minor version number.<code>True</code> will be
returned if the function succeeds. <code>False</code> will be returned
if the function fails due to invalid parameters. The <code>dpy</code>
argument is currently ignored, but should be the value returned by
XOpenDisplay.</p>
<p>At compile time, the Mini GLX interface version can be tested with
the MINI_GLX_VERSION_1_<i>x</i> preprocessor tokens. For example, if
version 1.0 of Mini GLX is supported, then<code> MINI_GLX_VERSION_1_0</code>
will be defined. If version 1.1 of Mini GLX is supported, then<code>
MINI_GLX_VERSION_1_1</code> will be defined.</p>
<p>At the time of writing the current Mini GLX version is 1.0.<br>
<br>
</p>
<h1>4.0 Interoperability with GLX and Xlib</h1>
While Mini GLX strives to be compatible with GLX and Xlib there are
some unavoidable differences which must be taken into consideration.<br>
<h2>4.1 Public vs Private Structures</h2>
The structure of many X data types is public. &nbsp;For example, the <code>Display</code>
data type is defined as a structure in /usr/include/X11/Xlib.h and
programmers may access any fields of that structure at will. &nbsp;Mini
GLX also defines a Display data type but its fields are hidden and not
visiblein <code>miniglx.h</code>. &nbsp;Duplicating the Xlib
declaration for the <code>Display</code> data type in minigl.h would
require defining a large number of other superfluous Xlib datatypes.<br>
<br>
Mini GLX users are discouraged from directly accessing the fields of
Xlib data types to maximize portability - though this is unavoidable to
some extent. &nbsp;For example, the <code>XVisualInfo</code> and <code>XSetWindowAtttributes</code>
data types must be completely public.
<h2>4.2 Macros</h2>
In some cases, Xlib defines macros which are meant to be used instead
of direct structure accesses. &nbsp;For example, the <code>RootWindow(dpy,
screen)</code> macro returns the root window for a given screen on a
given display. &nbsp;Unfortunately, macros do nothing to aid in ABI
compatibility since they are resolved at compile time instead of at
link/run time.<br>
<br>
Mini GLX also defines a <code>RootWindow</code> macro since it's
essential for creating windows. &nbsp;But the implementation of this
macro by Xlib and Mini GLX is completely different.<br>
<h2>4.3 Summary</h2>
Because Xlib and Mini GLX define data types and macros differently,
Mini GLX applications must be recompiled when retargeting Mini GLX or
native Xlib/GLX. &nbsp;That is, applications can't simply be re-linked
because of ABI incompatibilities.<br>
<br>
Nevertheless, the fact that Mini GLX programs can be recompiled for
Xlib and GLX increases portability and flexibility for testing and
prototyping.<br>
<br>
<h1>5.0 Example Program</h1>
<p>This section shows an example program which uses the Mini GLX
interface. The program simply draws several frames of a rotating square.<br>
</p>
<p>The program may be compiled for use with Xlib/GLX or Mini GLX by
setting the <code>USE_MINIGLX</code> token to 0 or 1, respectively.
&nbsp;Note that the only difference is the header files which are
included.<br>

Mesa-4.0.3 BeOS R5 driver patch
Version alpha v0.3
Mesa / BeOS Information
HOW TO BUILD:
1) You need gcc 2.95.3 to be installed:
http://www.bebits.com/app/2157
Check your installed gcc version by running this command from a Terminal:
gcc -v
2) Download Mesa-4.0.3 sources
http://prdownloads.sourceforge.net/mesa3d/MesaLib-4.0.3.tar.gz?download
* Introduction
3) Extract official 4.0.3 sources code somewhere
Mesa 4.1 features a driver for the BeOS. The driver implements
a clone of the BGLView class. This class, derived from BView, allows
OpenGL rendering into a BeOS window.
The 4.1 BeOS driver is an update of Brian Paul's BeOS driver released in Mesa 3.1.
4) Then, extract the BeOS driver patch at same place. This will
overwrite modified sources and add BeOS-specific ones.
Any application which uses the BGLView should be able to use Mesa
instead of Be's OpenGL without changing any code.
5) Open a new Terminal window:
$ cd /path/to/Mesa-4.0.3/src
$ make -f Makefile.BeOS-R5
Since Be's OpenGL implementation (as of R5) is basically just the
SGI sample implementation, it's pretty slow. You'll see that Mesa
is considerably faster.
6) Take a cup of coffee!
7) When done, you should find a obj.x86/libGL.so
8) To test this library as a Be Inc's one:
- rename /boot/beos/system/lib/libGL.so into libGL.so.r5
- put/copy obj.x86/libGL.so file into /boot/home/config/lib directory
- run GLTeapot...
* Source Code
To see more information, run your(s) GL app(s) from Terminal:
$ export MESA_INFO=1
$ export MESA_DEBUG=1
$ myGLapp
MMX cpu detected.
Not testing OS support for SSE, leaving enabled.
SSE cpu detected.
Mesa GL_VERSION = 1.2 Mesa 4.0.3
Mesa GL_RENDERER = BGLView
Mesa GL_VENDOR = Brian Paul
Mesa GL_EXTENSIONS = GL_ARB_imaging GL_ARB_multitexture
[...]
GL_SGIX_shadow GL_SGIX_shadow_ambient
Mesa thread-safe: NO
Mesa x86-optimized: YES
Mesa sparc-optimized: NO
The source code for the driver is in Mesa-4.1/src/BeOS/ directory.
It's not 100% finished at this time but many GLUT-based demos are
working. No optimizations have been made at this time.
BUILD ISSUES:
- If the build stop on math/m_*.c files, you're not using gcc 2.95.3.
- The Makefile.BeOS-R5 is set currently to build a non-debug x86/mmx/sse/3dnow optimized libGL.so.
It's a modified BeOS standard makefile, so editing it to follow your needs should be easy...
- NASM support instead of built-in gcc assembler (GAS) is not supported yet...
- "Mesa thread-safe: NO" is correct: the Mesa multithread support don't allow to share a gl context
between any thread, only give you one thread <-> one context, which is inaccurate under BeOS...
KNOWN LIMITATIONS & BUGS:
- BeOS driver only support software rendition ATM
- No BDirectWindow support yet, too. GLLife will not work for this reason.
- 3dnow support untested
- GLTeapot: object mouse control don't work
- GLTeapot: window resizing don't work
- many others: ALPHA VERSION, remember.
* Compiling
Requirements:
- gcc version 2.95.3 for BeOS
You can find it here: http://www.bebits.com/app/2157
Move to the Mesa-4.x src sub-directory and then type "make -f Makefile.BeOS-R5".
When it finishes the Mesa based libGL.so library for
BeOS will be in the Mesa-4.x/src/obj.{x86|ppc}/ directory.
To install it as Be's default libGL.so replacement, put it in your
/boot/home/config/lib/ directory. All your GL/GLUTapps will use
the Mesa based then.
By default, it build a non-debug version library.
The x86 (MMX, SSE and 3DNOW) optimizations are also supported for x86 target.
Sorry, Mesa don't have ppc (Altivec) optimizations yet.
* Example Programs
Look in the Mesa-4.x/BeOS/ directory for one or two BGLView demo
programs. They should have been compiled along with the Mesa
library.
* GLUT
A beta version of GLUT 3.7 port for BeOS can be found at
http://anobject.com/jehamby/Code/Glut-3.7-x86.zip.
There's is a 2.5 version in src-glut.beos/, too.
The original distribution can be obtained from
http://home.beoscentral.com/jehamby/Glut-3.5-x86.zip
They are special version of GLUT adapted for the BeOS. I don't
believe Mark Kilgard's normal GLUT distribution includes BeOS
support.
* Special Features
Mesa's implementation of the BGLView class has an extra member
function: CopySubBufferMESA(). It basically works like SwapBuffers()
but it only copies a sub region from the back buffer to the front
buffer. This is a useful optimization for some applications.
If you use this method in your code be sure that you check at runtime
that you're actually using Mesa (with glGetString) so you don't
cause a fatal error when running with Be's OpenGL.
* Work Left To Do
BDirectWindow single buffering support is not implemented yet.
Color index mode is not implemented yet.
Reading pixels from the front buffer not implemented yet.
There is also a BGLScreen class in BeOS for full-screen OpenGL
rendering. This should also be implemented for Mesa.
* Old BeOS Driver
Mesa 2.6 had an earlier BeOS driver. It was based on Mesa's Off-screen
rendering interface, not BGLView. If you're interested in the older
driver you should get Mesa 2.6.
* BeOS and Glide
Mesa 3.0 supported the 3Dfx/Glide library on Beos. Download Mesa 3.0
if interested. Ideally, the 3Dfx/Glide support should be updated to
work with the new Mesa 3.1 BGLView implementation.
The Glide library hasn't been updated for BeOS R4, to my knowledge, as
of February, 1999.

FAQ:
~~~~
1. Compilation
Q) `make' barfs and exits because it cannot find some stupid file.
A) You need LFN support.
A) When compiling for Glide (FX=1), pay attention to Glide path.
Q) Libraries built OK, but linker complains about `vsnprintf' every time I
compile some demo.
A) Upgrade to DJGPP 2.04.
A) Add `vsnprintf.c' to the CORE_SOURCES in `src/Makefile.DJ' (untested!).
A) Patch `src/mesa/main/imports.c' with the following line:
#define vsnprintf(buf, max, fmt, arg) vsprintf(buf, fmt, arg)
This hack should be safe in 90% of the cases, but if anything goes wrong,
don't come back to me crying.
Q) `make' complains about DXE3 or something, yet it builds the libraries.
A) DXE3 refers to the DJGPP dynamic modules. You'll need either the latest
DJGPP distro, or download the separate package from my web page. Read the
DXE3 documentation on how to use them.
A) When compiling for Glide (FX=1), make sure `glide3x.dxe' can be found in
LD_LIBRARY_PATH (or top `lib' directory).
2. Using Mesa for DJGPP
Q) DMesa is so SLOOOW! The Win32 OpenGL performs so much better...
A) Is that a question? If you have a 3dfx Voodoo Banshee or higher card,
you're lucky (check http://sourceforge.net/projects/glide for the DJGPP
port). If you have a Matrox Millennium I card, you just MIGHT be lucky...
If you haven't, sorry; everything is done in software. Suggestions?
Q) I tried to set refresh rate w/ DMesa, but without success.
A) Refresh rate control works only for VESA 3.0. If you were compiling for
Glide, see Glide info. If not, sorry!
Q) I made a simple application and it does nothing. It exits right away. Not
even a blank screen.
A) The pure software drivers (VESA/VGA) support only double-buffered modes.
A) Another weird "feature" is that buffer width must be multiple of 8 (I'm a
lazy programmer and I found that the easiest way to keep buffer handling
at peak performance ;-).
Q) The GLUT is incomplete.
A) See below.
libGLUT (the toolkit):
~~~~~~~~~~~~~~~~~~~~~~
Well, this "skeletal" GLUT implementation was taken from AllegGL project and
heavily changed. Thanks should go to Bernhard Tschirren, Mark Kilgard, Brian
Paul and probably others (or probably not ;-). GLUT functionality will be
extended only on an "as needed" basis.
GLUT talks to hardware via PC_HW package which was put together from various
pieces I wrote long time ago. It consists from the keyboard, mouse and timer
drivers.
My keyboard driver used only scancodes; as GLUT requires ASCII values for keys,
I borrowed the translation tables (and maybe more) from Allegro -- many thanks
to Shawn Hargreaves et co. Ctrl-Alt-Del (plus Ctrl-Alt-End, for Windows users)
will shut down the GLUT engine unconditionally: it will raise SIGINT, which in
turn will (hopefully) call the destructors, thus cleaning up your/my mess ;-)
NB: since the DJGPP guys ensured signal handlers won't go beyond program's
space (and since dynamic modules shall) the SIGINT can't be hooked (well, it
can, but it is useless), therefore you must live with the 'Exiting due to
signal SIGINT' message...
The mouse driver is far from complete (lack of drawing, etc), but is enough to
make almost all the demos work. Supports the CuteMouse WheelAPI.
The timer is pretty versatile for it supports multiple timers with different
frequencies. While not being the most accurate timer in the known universe, I
think it's OK. Take this example: you have timer A with a very high rate, and
then you have timer B with very low rate compared to A; now, A ticks OK, but
timer B will probably loose precision!
As an addition, stdout and stderr are redirected and dumped upon exit. This
means that `printf' can be safely called during graphics. A bit of a hack, I
know, because all messages come in bulk, but I think it's better than nothing.
"Borrowed" from LIBRHUTI (Robert Hoehne).
Window creating defaults: (0, 0, 300, 300), 16bpp. However, the video mode is
chosen in such a way that first window will fit. If you need high resolution
with small windows, set initial position far to the right (or way down); then
you can move them back to any position right before the main loop.
The following environment variables can customize GLUT behaviour:
GLUT_FPS - print frames/second statistics to stderr
DMESA_GLUT_REFRESH - set vertical screen refresh rate (VESA3)
DMESA_GLUT_BPP - set default bits per pixel (VGA needs 8)
DMESA_GLUT_ALPHA - set default alpha bits (8)
DMESA_GLUT_DEPTH - set default depth bits (16)
DMESA_GLUT_STENCIL - set default stencil bits (8)
DMESA_GLUT_ACCUM - set default accum bits (16)

FAQ:
~~~~
1. Compilation
Q) I tried to run `make' and it exits because `gcc' complains it cannot find
some stupid file.
A) You need LFN support.
A) When compiling for Glide (FX=1), pay attention to Glide path.
2. Dynamic modules
Q) What are you mumbling about dynamic modules?
A) You must have the DXE2 package (available on SimTel.Net, courtesy of
Andrew Zabolotny) installed in order to build the dynamic modules.
Q) I have DXE2, but I couln'd build the `dxe2gen.exe'.
Q) I built `dxe2gen.exe', but it doesn't do the job right.
A) There is a patched version on my web page.
Q) DXE2 modules give me headaches...
A) The DXE2 modules are not compulsory. The static libraries are still built
and you can use them in the old-fashioned, classic way. For example:
gcc -o OUT.exe IN.c -lglut -lglu -lgl
Q) Okay, DXE2 modules are built. How can I use them?
A) Usage of the dynamic modules requires three things:
- include DMESADXE.H in one of the sources, so references inside
dynamic modules will get resolved (or use `-include' directive).
- link against import libraries (libI*.a) and LIBDL.A, which will do
the dynamic linkage job for you
- put the DXEs somewhere along the library path (LD_LIBRARY_PATH) or
in the current directory
For example:
gcc -o OUT.exe -include dmesadxe.h IN.c -ligl -liglu -liglut -ldl
Q) The application dies with "Abort!" due to unresolved symbols.
A) This is bad! Extract the unresolved symbol list from this module. For
example:
dxe2gen --show-unres gl.dxe > u
Check DMESADXE.H; the symbols in `u' must either be present here or be
exported from another module that has to be loaded before your faulting
one. Then recompile.
3. Using Mesa for DJGPP
Q) Does this build work in Win9x?
A) Yes.
Q) Does it work under NT (W2k, XP) core?
A) Uh... probably not!
Q) I made a simple application and it does nothing. It exits right away. Not
even a blank screen.
A) The current version supports only RGB[A] modes, for it made no sense to
me to endorse color-index (aka palette) modes.
A) Single-buffered is not allowed at all. Until I can find a way to use
*REAL* hardware acceleration, it won't get implemented.
A) Another weird "feature" is that buffer width must be multiple of 4 (I'm a
lazy programmer and I found that the easiest way to keep buffer handling
at peak performance ;-).
Q) My demo doesn't display text. I know I used the glut font routines!
A) Then you probably use GLUT as a DXE. Well, there is no direct access to
variables due to the way DXE works. Read the documentation. The author of
GLUT took this into account for _WIN32 DLL's only; I don't want to modify
his headers. The only workaround is to link GLUT the old way :-(
Q) The DJGPP port of Mesa is so SLOOOW! The Win32 OpenGL performs so much
better...
A) Is that a question? If you have a Voodoo3/Banshee card, you're lucky. The
Glide port is on my web page. If you haven't, sorry; everything is done
in software. Suggestions?
Q) I have a super/mega/ultra monitor and all you can do is 60Hz? My eyes are
leaking from the orbits...
A) If you were compiling for Glide, see Glide info. If not, be aware that
refresh rate control works only for VESA 3.0. The environment variable
DMESA_REFRESH sets the default screen refresh. For example:
set DMESA_REFRESH=75
libGLUT (the toolkit):
~~~~~~~~~~~~~~~~~~~~~~
Well, this "skeletal" GLUT implementation is not mine. Thanks should go to
Bernhard Tschirren, Mark Kilgard, Brian Paul and probably others (or probably
not ;-). I only changed it to be self-standing (Allegro-free). The keyboard,
mouse and timer drivers were inspired from an old project of mine (D3Xl) and
fixed with many Allegro "infusions"; I deeply thank to Shawn Hargreaves et co.
My keyboard driver used only scancodes, but since GLUT requires ASCII values
for keys, I borrowed the translation tables (and maybe more) from Allegro.
Ctrl-Alt-Del (plus Ctrl-Alt-End, for Windows users) will shut down the GLUT
engine unconditionally: it will raise SIGINT, which in turn will call the
destructors (let's hope), thus cleaning up your/my mess ;-) NB: since the
DJGPP guys ensured signal handlers won't go beyond program's space (and since
dynamic modules shall) the SIGINT can't be hooked (well, it can, but it is
useless), therefore you must live with the 'Exiting due to signal SIGINT'
message...
The mouse driver is far from complete (lack of positioning, drawing, etc),
but is enough to make almost all the demos work.
The timer is pretty versatile for it supports multiple timers with different
frequencies. It may not be the most accurate timer in the known universe, but
I think it's OK. Take this example: you have timer A with a very high rate,
and then you have timer B with very low rate compared to A; now, A ticks OK,
but timer B will probably loose precision!
As an addition, stdout and stderr are redirected and dumped upon exit. This
means that printf can be safely called during graphics, but all messages come
in bulk! A bit of a hack, I know, but I think it's better than to miss them

Last updated: Sep 18, 2003 - Karl Schultz - kschultz@users.sourceforge.net
Last updated: Aug 15, 2002 - Karl Schultz - kschultz@users.sourceforge.net
Quick Start
Unzip both ZIP files (MesaLib and MesaDemos) into the same directory.
The libs and demos build separately, so if you do not care about the
demos, you do not have to unzip that zip file. But if you do, it does
need to be unzipped into the same directory as the lib zip file because
the demos depend on the libs.
The build system has been changed to use Microsoft Visual Studio project
workspaces and projects. Makefiles are no longer shipped or supported, but
can be generated from the projects using Visual Studio.
If you have Microsoft Visual C++ 6.0 installed, simply go to the top directory
of the Mesa distribution and type 'nmake -f Makefile.win NODEBUG=1' for
an optimized build. Note that you may have to run ...VC98/BIN/VCVARS32.BAT
to set up the appropriate compiler environment variables.
Details and Notes
- To build the Mesa libraries, open the Mesa.dsw workspace file
in the top directory. You can build each project one-by-one,
or build the glut project to build everything except osmesa,
which needs to be built separately. The build process will
create a lib directory in the top directory and will put the
following files there:
OPENGL32.LIB, GLU32.LIB, GLUT32.LIB, OSMESA32.LIB
OPENGL32.DLL, GLU32.DLL, GLUT32.DLL, OSMESA32.DLL
- Building Mesa as noted above should visit and build the following:
src MesaGL.dll, MesaGL.lib, osmesa.dll, osmesa.lib
si-glu MesaGLU.dll, MesaGLU.lib
src-glut glut32.dll, glut32.lib
demos a handful of demo executables.
- After building, you can copy the above DLL files to a place in your PATH
such as $SystemRoot/SYSTEM32. If you don't like putting things in a
system directory, place them in the same directory as the executable(s).
Be careful about accidentially overwriting files of the same name in
the SYSTEM32 directory.
For example, you can copy the DLL files to the demos directory if you
just want to run the demos. The build process places the DLL and LIB files
in the ./lib directory. The makefile creates this directory if it does
not already exist.
- Build the demos by opening the appropriate *.dsw file in the
progs directory tree. For example, to build the demos, use
progs/demos/Windows/demos.dsw. The Windows directory contains
the workspace and all the projects for each demo program. Each
project places the executable in the same directory as its source
code, which is required for some demos.
- The make targets 'clean' and 'clobber' will remove objects and libraries.
But the files in ./lib are never cleaned.
- The demo projects also copy the Mesa library DLL files from the lib
directory into the same directory as the demo executables, so that
the demos use the Mesa libs you just built.
- The make target 'install' will take its best shot at copying DLL files,
LIB files, and headers to the right places. I strongly suggest that
you examine the makefiles to make sure that 'install' doesn't do anything
that you can't live with.
- The makefiles are designed to work with Microsoft's NMAKE, and do,
unfortunately, have some Microsoft-specific things in them. If you
would like to use gcc or some other build tools like the Cygnus tools,
then you will have to hack the makefiles to make them work with your
tools. I'm sorry about this; I wasn't motivated to make this any
different, but if you end up modifying the makefiles for your tools,
you can send me the changes and I can apply the changes to the
source tree.
- There are no Microsoft Visual Studio project files. However, these
should be very easy to create. One can use the compiler and linker
options found in the makefiles to make quick progress in creating
projects.
- The DLL files are built so that the external entry points use the
stdcall calling convention.
- Static LIB files are not built. The LIB files that are built with
are the linker import files associated with the DLL files.
the current makefiles are the linker import files associated with
the DLL files. If static LIB's are desired, it should not be too
difficult to modify the makefiles to generate them.
- The si-glu sources are used to build the GLU libs. This was done
mainly to get the better tessellator code.

New Features in Mesa 4.1
------------------------
New extensions. Docs at http://oss.sgi.com/projects/ogl-sample/registry/
<to be determined>
GL_NV_vertex_program
NVIDIA's vertex programming extension
GL_NV_vertex_program1_1
A few features built on top of GL_NV_vertex_program
GL_ARB_window_pos
This is the ARB-approved version of GL_MESA_window_pos
GL_ARB_depth_texture
This is the ARB-approved version of GL_SGIX_depth_texture.
It allows depth (Z buffer) data to be stored in textures.
This is used by GL_ARB_shadow
GL_ARB_shadow
Shadow mapping with depth textures.
This is the ARB-approved version of GL_SGIX_shadow.
GL_ARB_shadow_ambient
Allows one to specify the luminance of shadowed pixels.
This is the ARB-approved version of GL_SGIX_shadow_ambient.
GL_EXT_shadow_funcs
Extends the set of GL_ARB_shadow texture comparision functions to
include all eight of standard OpenGL dept-test functions.
GL_ARB_point_parameters
This is basically the same as GL_EXT_point_parameters.
GL_ARB_texture_env_crossbar
Allows any texture combine stage to reference any texture source unit.
GL_NV_point_sprite
For rendering points as textured quads. Useful for particle effects.
GL_NV_texture_rectangle (new in 4.0.4 actually)
Allows one to use textures with sizes that are not powers of two.
Note that mipmapping and several texture wrap modes are not allowed.
GL_EXT_multi_draw_arrays
Allows arrays of vertex arrays to be rendered with one call.
GL_EXT_stencil_two_side
Separate stencil modes for front and back-facing polygons.
GLX_SGIX_fbconfig & GLX_SGIX_pbuffer
Off-screen rendering support.
GL_ATI_texture_mirror_once
Adds two new texture wrap modes: GL_MIRROR_CLAMP_ATI and
GL_MIRROR_CLAMP_TO_EDGE_ATI.
Device Driver Status
--------------------
A number of Mesa's software drivers haven't been actively maintained for
some time. We rely on volunteers to maintain many of these drivers.
Here's the current status of all included drivers:
Driver Status
---------------------- ---------------------
XMesa (Xlib) implements OpenGL 1.3
OSMesa (off-screen) implements OpenGL 1.3
FX (3dfx Voodoo1/2) implements OpenGL 1.3
SVGA implements OpenGL 1.3
Wind River UGL implements OpenGL 1.3
Windows/Win32 implements OpenGL 1.3
DOS/DJGPP implements OpenGL 1.3
GGI implements OpenGL 1.3
BeOS needs updating (underway)
Allegro needs updating
D3D needs updating
DOS needs updating
New features in GLUT
--------------------
1. Frames per second printing
GLUT now looks for an environment variable called "GLUT_FPS". If it's
set, GLUT will print out a frames/second statistic to stderr when
glutSwapBuffers() is called. By default, frames/second is computed
and displayed once every 5 seconds. You can specify a different
interval (in milliseconds) when you set the env var. For example
'export GLUT_FPS=1000' or 'setenv GLUT_FPS 1000' will set the interval
to one second.
NOTE: the demo or application must call the glutInit() function for
this to work. Otherwise, the env var will be ignored.
Finally, this feature may not be reliable in multi-window programs.
2. glutGetProcAddress() function
The new function:
void *glutGetProcAddress(const char *procName)
is a wrapper for glXGetProcAddressARB() and wglGetProcAddress(). It
lets you dynamically get the address of an OpenGL function at runtime.
The GLUT_API_VERSION has been bumped to 5, but I haven't bumped the
GLUT version number from 3.7 since that's probably Mark Kilgard's role.
This function should probably also be able to return the address of
GLUT functions themselves, but it doesn't do that yet.
XXX Things To Do Yet XXXX
-------------------------
isosurf with vertex program exhibits some missing triangles (probably
when recycling the vertex buffer for long prims).
Porting Info
------------
If you're porting a DRI or other driver from Mesa 4.0.x to Mesa 4.1 here
are some things to change:
1. ctx->Texture._ReallyEnabled is obsolete.
Since there are now 5 texture targets (1D, 2D, 3D, cube and rect) that
left room for only 6 units (6*5 < 32) in this field.
This field is being replaced by ctx->Texture._EnabledUnits which has one
bit per texture unit. If the bit k of _EnabledUnits is set, that means
ctx->Texture.Unit[k]._ReallyEnabled is non-zero. You'll have to look at
ctx->Texture.Unit[k]._ReallyEnabled to learn if the 1D, 2D, 3D, cube or
rect texture is enabled for unit k.
This also means that the constants TEXTURE1_*, TEXTURE2_*, etc are
obsolete.
The tokens TEXTURE0_* have been replaced as well (since there's no
significance to the "0" part:
old token new token
TEXTURE0_1D TEXTURE_1D_BIT
TEXTURE0_2D TEXTURE_2D_BIT
TEXTURE0_3D TEXTURE_3D_BIT
TEXTURE0_CUBE TEXTURE_CUBE_BIT
<none> TEXTURE_RECT_BIT
These tokens are only used for the ctx->Texture.Unit[i].Enabled and
ctx->Texture.Unit[i]._ReallyEnabled fields. Exactly 0 or 1 bits will
be set in _ReallyEnabled at any time!
Q: "What's the purpose of Unit[i].Enabled vs Unit[i]._ReallyEnabled?"
A: The user can enable GL_TEXTURE_1D, GL_TEXTURE_2D, etc for any
texure unit all at once (an unusual thing to do).
OpenGL defines priorities that basically say GL_TEXTURE_2D has
higher priority than GL_TEXTURE_1D, etc. Also, just because a
texture target is enabled by the user doesn't mean we'll actually
use that texture! If a texture object is incomplete (missing mip-
map levels, etc) it's as if texturing is disabled for that target.
The _ReallyEnabled field will have a bit set ONLY if the texture
target is enabled and complete. This spares the driver writer from
examining a _lot_ of GL state to determine which texture target is
to be used.
2. Tnl tokens changes
During the implementation of GL_NV_vertex_program some of the vertex
buffer code was changed. Specifically, the VERT_* bits defined in
tnl/t_context.h have been renamed to better match the conventions of
GL_NV_vertex_program. The old names are still present but obsolete.
Drivers should use the newer names.
For example: VERT_RGBA is now VERT_BIT_COLOR0 and
VERT_SPEC_RGB is now VERT_BIT_COLOR1.
3. Read/Draw Buffer changes
The business of setting the current read/draw buffers in Mesa 4.0.x
was complicated. It's much simpler now in Mesa 4.1.
Here are the changes:
- Renamed ctx->Color.DrawDestMask to ctx->Color._DrawDestMask
- Removed ctx->Color.DriverDrawBuffer
- Removed ctx->Pixel.DriverReadBuffer
- Removed ctx->Color.MultiDrawBuffer
- Removed ctx->Driver.SetDrawBuffer()
- Removed swrast->Driver.SetReadBuffer().
- Added ctx->Color._DrawDestMask - a bitmask of FRONT/BACK_LEFT/RIGHT_BIT
values to indicate the current draw buffers.
- Added ctx->Pixel._ReadSrcMask to indicate the source for pixel reading.
The value is _one_ of the FRONT/BACK_LEFT/RIGHT_BIT values.
- Added ctx->Driver.DrawBuffer() and ctx->Driver.ReadBuffer().
These functions exactly correspond to glDrawBuffer and glReadBuffer calls.
Many drivers will set ctx->Driver.DrawBuffer = _swrast_DrawBuffer and
leave ctx->Draw.ReadBuffer NULL.
DRI drivers should implement their own function for ctx->Driver.DrawBuffer
and use it to set the current hardware drawing buffer. You'll probably
also want to check for GL_FRONT_AND_BACK mode and fall back to software.
Call _swrast_DrawBuffer() too, to update the swrast state.
- Added swrast->Driver.SetBuffer().
This function should be implemented by all device drivers that use swrast.
Mesa will call it to specify the buffer to use for span reading AND
writing and point/line/triangle rendering.
There should be no confusion between current read or draw buffer anymore.
- Added swrast->CurrentBuffer to indicate which color buffer to read/draw.
Will be FRONT_LEFT_BIT, BACK_LEFT_BIT, FRONT_RIGHT_BIT or BACK_RIGHT_BIT.
This value is usually passed to swrast->Driver.SetBuffer().
4. _mesa_create_context() changes. This function now takes a pointer to
a __GLimports object. The __GLimports structure contains function
pointers to system functions like fprintf(), malloc(), etc.
The _mesa_init_default_imports() function can be used to initialize
a __GLimports object. Most device drivers (like the DRI drivers)
should use this.
5. In tnl's struct vertex_buffer, the field "ProjectedClipCoords"
has been replaced by "NdcPtr" to better match the OpenGL spec's
terminology.
6. Since GL_EXT_stencil_two_side has been implemented, many of the
ctx->Stencil fields are now 2-element arrays. For example,
"GLenum Ref" is now "GLenum Ref[2]" The [0] elements are the front-face
values and the [1] elements are the back-face values.
ctx->Stencil.ActiveFace is 0 or 1 to indicate the current face for
the glStencilOp/Func/Mask() functions.
ctx->Stencil.TestTwoSide controls whether or not 1 or 2-sided stenciling
is enabled.
7. Removed ctx->Polygon._OffsetAny. Removed ctx->Polygon.OffsetMRD.
8. GLfloat / GLchan changes:
- Changed ctx->Driver.ClearColor() to take GLfloat[4] instead of GLchan[4].
ctx->Color.ClearColor is now GLfloat[4] too.
- Changed ctx->Driver.AlphaRef() to take GLfloat instead of GLchan.
- ctx->Color.AlphaRef is now GLfloat.
- texObj->BorderColor is now GLfloat[4]. texObj->_BorderChan is GLchan[4].
This is part of an effort to remove all GLchan types from core Mesa so
that someday we can support 8, 16 and 32-bit color channels dynamically
at runtime, instead of at compile-time.
9. GLboolean ctx->Tranform.ClipEnabled[MAX_CLIP_PLANES] has been replaced
by GLuint ctx->Transform.ClipPlanesEnabled. The later is a bitfield.
10. There's a new matrix_stack type in mtypes.h used for the Modelview,
Projection, Color and Texcoord matrix stacks.
11. The ctx->Current.* fields have changed a lot. Now, there's a
ctx->Current.Attrib[] array for all vertex attributes which matches
the NV vertex program conventions.

New Features in Mesa 5.1
------------------------
GL_ATI_texture_env_combine3 extension
This adds a few new texture combine modes.
Contributed by Ian Romanick.
GL_SGI_texture_color_table
Adds a color table lookup to the RGBA texture path. There's a separate
color table for each texture unit.
Contributed by Eric Plante.
GL_NV_fragment_program
NVIDIA's fragment-level programming feature.
Possible lurking bugs:
- the DDX and DDY commands aren't fully tested
- there may be bugs in the parser
- the TEX and TXP instructions both do perspective correction
- the pack/unpack instructions may not be correct
GL_EXT_depth_bounds_test
This extension adds a scissor-like test for the Z axis. It's used to
optimize stencil-volume shadow algorithms.
GL_NV_light_max_exponent
Lifts the 128 limit for max light exponent.
GL_EXT_texture_rectangle
Identical to GL_NV_texture_rectangle
GL_ARB_occlusion_query
Useful for visibility-based culling.
GL_ARB_texture_non_power_of_two
Removes the restriction that texture dimensions must be powers of two.
GL_ARB_vertex_buffer_object
Allows server-side vertex arrays, optimized host/card data transfers, etc.
GL_ARB_point_sprite
ARB-approved version of GL_NV_point_sprite. Basically allows textures
to be applied to points.
GL_IBM_multimode_draw_arrays
Allows multiple vertex arrays to be drawn with one call, including arrays
of different types of primitives.
GL_SUN_multi_draw_arrays
An alias for GL_EXT_multi_draw_arrays, standard in OpenGL 1.4.
With the addition of GL_ARB_occlusion_query, GL_ARB_vertex_buffer_object,
GL_ARB_texture_non_power_of_two and GL_EXT_shadow_funcs, Mesa 5.1 supports
all the new features of OpenGL 1.5. Mesa 6.0 (the next stable release)
will advertise GL_VERSION = "1.5".
Vertex/Fragment program debugger
--------------------------------
GL_MESA_program_debug is an experimental extension to support
interactive debugging of vertex and fragment programs. See the
docs/MESA_program_debug.spec file for details.
The bulk of the vertex/fragment program debugger is implemented
outside of Mesa. The GL_MESA_program_debug extension just has minimal
hooks for stopping running programs and inspecting programs.
The progs/tests/debugger.c (only in CVS) program is an example of how
the extension can be used. Presently, the debugger code and demo code
is in the same file. Eventually the debugger code should be moved
into a reusable module.
As it is now, the demo lets you set breakpoings in vertex/fragment
programs, single step, and print intermediate register values. It's
basically just a proof of concept.
Directory tree reorganization
-----------------------------
The directory structure for Mesa has been overhauled to improve its layout.
All source code for Mesa, GLU, GLUT, etc is now under the src/ directory
in appropriate subdirectories.
The Mesa source code and drivers has been reorganized under src/mesa/.
All demonstration programs and tests are now in subdirectories under progs/.
Build System Changes
--------------------
The GNU automake/autoconf support has been removed. As it was, it seldom
worked on anything but Linux. The Mesa developers aren't big fans of
automake/autoconf/libtool and didn't have the time to maintain it.
If someone wants to contribute new automake/autoconf support (and is
willing to maintain it), it may be re-incorporated into Mesa, subject
to some requirements.
The "old style" makefile system has been updated:
1. Make-config has been trimmed down to fewer, modern configurations.
2. Most of the bin/mklib.* scripts have been rolled into a new "mklib"
script that works on all sorts of systems. There are probably some
bugs in it, but it's been tested on Linux, SunOS 5.8 and IRIX 6.5.
Improvements/contributes are greatly appreciated.
3. The Makefile.X11 files have been cleaned up in various ways
Source File Changes
-------------------
The mmath.[ch] files are obsolete. Their contents have been moved
into the imports.[ch] and macros.[ch] files.
The files related to vertex and fragment programming have changed.
Old files:
vpexec.[ch]
vpparse.[ch]
vpstate.[ch]
New files:
program.[ch] - generic ARB/NV program code
arbprogram.[ch] - ARB program API functions
nvprogram.[ch] - NV program API functions
nvvertprog.h - NV vertex program definitions
nvfragprog.h - NV fragment program definitions
nvvertparse.[ch] - NV vertex program parser
nvfragparse.[ch] - NV fragment program parser
nvvertexec.[ch] - NV vertex program execution
swrast/s_nvfragprog.[ch] - NV fragment program execution
Removed files:
swrast/s_histogram.[ch] - moved into src/histogram.c
Other New files:
bufferobj.[ch] - GL_ARB_vertex_buffer_object functions
version.h - defines the Mesa version info
Other Changes
-------------
The ctx->Driver.CreateTexture function has been removed - it wasn't used.
New device driver hook functions:
NewTextureObject - used to allocate struct gl_texture_objects
NewTextureImage - used to allocate struct gl_texture_images
New ctx->Texture._EnabledCoordUnits field:
With the addition of GL_NV_fragment_program we may need to interpolate
various sets of texture coordinates even when the corresponding texture
unit is not enabled. That is, glEnable(GL_TEXTURE_xD) may never get
called but we still may have to interpolate texture coordinates across
triangles so that the fragment program will get them.
This new field indicates which sets of texture coordinates are needed.
If a bit is set in the ctx->Texture._EnabledUnits bitmask is set, the
same bit MUST be set in ctx->Texture._EnabledCoordUnits.
The ctx->_TriangleCaps field is deprecated.
Instead of testing the DD_* bits in _TriangleCaps, you should instead
directly test the relevant state variables, or use one of the helper
functions like NEED_SECONDARY_COLOR() at the bottom of context.h
While testing _TriangleCaps bits was fast, it was kludgey, and setting
the bits in the first place could be error prone.
To Do
-----
Add screen-awareness to fakeglx.c
Device Driver Status
--------------------
A number of Mesa's software drivers haven't been actively maintained for
some time. We rely on volunteers to maintain many of these drivers.
Here's the current status of all included drivers:
Driver Status
---------------------- ---------------------
XMesa (Xlib) implements OpenGL 1.4
OSMesa (off-screen) implements OpenGL 1.4
FX (3dfx Voodoo1/2) implements OpenGL 1.3
SVGA implements OpenGL 1.3
Wind River UGL implements OpenGL 1.3
Windows/Win32 implements OpenGL 1.4
DJGPP implements OpenGL 1.4
GGI implements OpenGL 1.3
BeOS implements OpenGL 1.4
Allegro needs updating
D3D needs updating
Note: supporting OpenGL 1.4 (vs. 1.3 or 1.2) usually only requires that the
driver call the _mesa_enable_1_4_extensions() function.

<p>
The SGI OpenGL conformance tests verify correct operation of OpenGL
implementations. I, Brian Paul, have been given a copy of the tests
for testing Mesa. The tests are not publically available.
</p>
<p>
This file has the latest results of testing Mesa with the OpenGL 1.2
conformance tests. Testing with the preliminary OpenGL 1.3 tests has
also been done. Mesa passes all the 1.3 tests.
</p>
<p>
The tests were run using the software X11 device driver on 24-bpp
and 16-bpp displays.
</p>
<p>
Mesa 4.0 and later pass all conformance tests at all path levels.
Note that this says nothing about the conformance of hardware drivers
based upon Mesa.

<TITLE>CVS Branches</TITLE>
<BODY text="#000000" bgcolor="#55bbff" link="#111188">
<H1>CVS Branch Information</H1>
<p>
The Mesa3d sources are split up into two branches. A branch that is to
remain as stable as possible, and an unstable branch where development
work for new versions will be done. The current stable branch is
tagged <code>mesa_3_4_branch</code> while the unstable branch is just
the default. The goal is to adopt and even/odd stable/unstable
versioning scheme similar to the Linux kernel. Hence releases of Mesa
3.2.X should be more stable than Mesa 3.3.X.<p></p> <p>All versions of
Mesa after 3.0 will also be tagged with a branch id. Mesa 3.1 has the
tag <code>mesa_3_1</code>, Mesa 3.2 will be <code>mesa_3_2</code>,
Mesa 3.3 <code>mesa_3_3</code>, etc..</p>
<p>
To checkout a specific branch of mesa just pass <code>-r</code> and
the branch tag after your cvs command. For example <code>cvs checkout
-r mesa_3_4_branch Mesa</code> will checkout the 3.4 branch and
<code>cvs update -r mesa_3_4_branch</code> will convert your current
branch to the 3.4 dev branch.
Consult <a href="http://www.durak.org/cvswebsites/doc/cvs_5.php3#SEC54"
target="_parent">http://www.durak.org/cvswebsites/doc/cvs_5.php3#SEC54</a>
for more on branching in cvs.
</p>
<p>
To see a list of all the CVS branchs run <code>cvs log README</code> (or any
other file) and look for the section labeled <code>symbolic names</code>.
You'll see something like this:
</p>
<pre> symbolic names:
mesa_4_0: 1.3

<TITLE>Debugging Tips</TITLE>
<BODY text="#000000" bgcolor="#55bbff" link="#111188">
<H1>Debugging Tips</H1>
<p>
Normally Mesa (and OpenGL) records but does not notify the user of
errors. It is up to the application to call
<code>glGetError</code> to check for errors. Mesa supports an
environment variable, MESA_DEBUG, to help with debugging. If
MESA_DEBUG is defined, a message will be printed to stdout whenever
an error occurs.
</p>
<p>
More extensive error checking is done when Mesa is compiled with the
DEBUG symbol defined. You'll have to edit the Make-config file and
add -DDEBUG to the CFLAGS line for your system configuration. You may
also want to replace any optimization flags with the -g flag so you can
use your debugger. After you've edited Make-config type 'make clean'
before recompiling.
</p>
<p>
In your debugger you can set a breakpoint in _mesa_error() to trap Mesa
errors.
</p>
<p>
There is a display list printing/debugging facility. See the end of
src/dlist.c for details.

<H1>Development Notes</H1>
<H2>Adding Extentions</H2>
<p>
To add a new GL extension to Mesa you have to do the following.
<pre>
If glext.h doesn't define the extension, edit include/GL/gl.h and add:
- new enum tokens
- new API function entry points
- #define GL_EXT_the_extension_name 1
If adding a new API function (call it glNewFunctionEXT):
- insert glNewFunctionEXT()into src/apiext.h
- edit src/types.h and add NewFunction to the gl_api_table struct
- implement gl_NewFunction() in the appropriate src file
- hook gl_NewFunction() into pointers.c
- add display list support in dlist.c for save_NewFunction()
- add glNewFunctionEXT to gl_GetProcAddress() in extensions.c or
in the device driver's GetProcAddress() function if appropriate
</pre>
<p>
If adding new GL state be sure to update get.c and enable.c
</p>
<p>
In general, look for an extension similar to the new one that's already
implemented in Mesa and follow it by example.
</p>
<H2>Coding Style</H2>
<p>
Mesa's code style has changed over the years. Here's the latest.
</p>
<p>
Comment your code! It's extremely important that open-source code be
well documented. Also, strive to write clean, easily understandable code.
</p>
<p>
3-space indentation
</p>
<p>
If you use tabs, set them to 8 columns
</p>
<p>
Brace example:
</p>
<pre>
if (condition) {
foo;
}
else {
bar;
}
</pre>
<p>
Here's the GNU indent command which will best approximate my preferred style:
</p>
<pre>
indent -br -i3 -npcs infile.c -o outfile.c
</pre>
<p>
Local variable name example: localVarName (no underscores)
</p>
<p>
Constants and macros are ALL_UPPERCASE, with _ between words
</p>
<p>
Global vars not allowed.
</p>
<p>
Function name examples:
</p>
<pre>
glFooBar() - a public GL entry point (in dispatch.c)
_mesa_FooBar() - the internal immediate mode function
save_FooBar() - retained mode (display list) function in dlist.c
foo_bar() - a static (private) function
_mesa_foo_bar() - an internal non-static Mesa function

<H2>Making a New Mesa Release</H2>
<p>
These are the instructions for making a new Mesa release.
</p>
<p>
Prerequisites (later versions may work):
</p>
<ul>
<li> autoconf 2.50
<li> automake 1.4-p2
<li> libtool 1.4
</ul>
<p>
Be sure to do a "cvs update -d ." in the Mesa directory to
get all the latest files.
</p>
<p>
Update the version definitions in src/version.h
</p>
<p>
Create/edit the docs/RELNOTES-X.Y file to document what's new in the release.
Edit the docs/VERSIONS file too.
</p>
<p>
Edit Make-config and change the MESA_MAJOR and/or MESA_MINOR versions.
</p>
<p>
Edit the GNU configure stuff to change versions numbers as needed:
Update the version string (second argument) in the line
"AM_INIT_AUTOMAKE(Mesa, 3.3)" in the configure.in file.
</p>
<p>
Remove the leading `dnl' from the line "dnl AM_MAINTAINER_MODE".
</p>
<p>
Verify the version numbers near the top of configure.in
</p>
<p>
Run "fixam -f" to disable automatic dependency tracking.
</p>
<p>
Run the bootstrap script to generate the configure script.
</p>
<p>
Edit Makefile.X11 and verify DIRECTORY is set correctly. The Mesa
sources must be in that directory (or there must be a symbolic link).
</p>
<p>
Edit Makefile.X11 and verify that LIB_NAME and DEMO_NAME are correct.
If it's a beta release, be sure the bump up the beta release number.
</p>
<p>
cp Makefile.X11 to Makefile so that the old-style Mesa makefiles
still work. ./configure will overwrite it if that's what the user runs.
</p>
<p>
Make a symbolic link from $(DIRECTORY) to Mesa. For example,
ln -s Mesa Mesa-3.3 This is needed in order to make a correct
tar file in the next step.
</p>
<p>
Make the distribution files. From inside the Mesa directory:
<pre>
make -f Makefile.X11 lib_tar
make -f Makefile.X11 demo_tar
make -f Makefile.X11 lib_zip
make -f Makefile.X11 demo_zip
</pre>
<p>
Copy the distribution files to a temporary directory, unpack them,
compile everything, and run some demos to be sure everything works.
</p>
<p>
Upload the *.tar.gz and *.zip files to ftp.mesa3d.org
</p>
<p>
Update the web site.
</p>
<p>
Make an announcement on the mailing lists:
<em>m</em><em>e</em><em>s</em><em>a</em><em>3</em><em>d</em><em>-</em><em>d</em><em>e</em><em>v</em><em>@</em><em>l</em><em>i</em><em>s</em><em>t</em><em>s</em><em>.</em><em>s</em><em>f</em><em>.</em><em>n</em><em>e</em><em>t</em>,

</p>
<H2>Autoconf info</H2>
<p>
In order to run the bootstrap script you'll need:
<p>
<pre>
autoconf 2.50
automake 1.4-p5

<TITLE>Getting Mesa</TITLE>
<BODY text="#000000" bgcolor="#55bbff" link="#111188">
<H1>Downloading / Unpacking</H1>
<p>
Mesa can be downloaded from the
<a href="http://www.sourceforge.net/projects/mesa3d" target="_parent">
SourceForge download area</A>.
</p>
<p>
Since version 2.3, Mesa is distributed in two pieces: main library code
and demos. If you're upgrading from a previous version of Mesa or you're not
interested in the demos you can just download the core Mesa archive file.
</p>
<p>
Mesa is available in at least three archive formats:
</p>
<pre>
1. GNU zip/tar
Download MesaLib-X.Y.tar.gz and optionally MesaDemos-X.Y.tar.gz
Unpack with:
gzcat MesaLib-X.Y.tar.gz | tar xf -
gzcat MesaDemos-X.Y.tar.gz | tar xf -
or
gunzip MesaLib-X.Y.tar.gz ; tar xf MesaLib-X.Y.tar
gunzip MesaDemos-X.Y.tar.gz ; tar xf MesaLib-X.Y.tar
or
tar zxf MesaLib-X.Y.tar.gz
tar zxf MesaDemos-X.Y.tar.gz
If you don't have gzcat try zcat instead.
2. Unix compressed/tar
Download MesaLib-X.Y.tar.Z and optionally MesaDemos-X.Y.tar.Z
Unpack with:
zcat MesaLib-X.Y.tar.Z | tar xf -
zcat MesaDemos-X.Y.tar.Z | tar xf -
3. ZIP format
Download MesaLib-X.Y.zip and optionally MesaDemos-X.Y.zip
Unpack with:
unzip MesaLib-X.Y.zip
unzip MesaDemos-X.Y.zip
</pre>
<p>
After unpacking you'll have these directories (and more):
</p>
<pre>
Makefile.X11 - top-level Makefile for X11-based systems
Make-config - system configurations used by the Makefile.X11
include/ - GL header (include) files
bin/ - shell scripts for making shared libraries, etc
lib/ - final client libraries, created during compilation
docs/ - documentation
src/ - source code for libraries
src/mesa - sources for the main Mesa library and device drivers
src/glu - libGLU source code
src/glw - Xt/Motif/OpenGL widget code
and if you downloaded and unpacked the MesaDemos.X.Y archive:
src/glut - GLUT source code
progs/ - OpenGL programs
progs/demos - original Mesa demos
progs/xdemos - GLX OpenGL/Mesa demos
progs/redbook - examples from the OpenGL Programming Guide
progs/samples - examples from SGI
progs/images/ - image files
</pre>
<p>
Proceed to <a href="install.html">compilation and installation
instructions</a>.
</p>
<H1>GLUT</H1>
<p>
Mesa 2.5 and later includes Mark Kilgard's GLUT library (GL Utility Toolkit).
GLUT is built automatically on systems which support it.
</p>
<p>
The GLUT tests, demos, examples, etc are not included, just the main library.
To obtain the latest complete release of GLUT please visit the

</a><h1><a name="part1">1. High-level Questions and Answers</a></h1>
<h2><a name="part1">1.1 What is Mesa?</a></h2>
<p>
<a name="part1">Mesa is an open-source implementation of the OpenGL specification.
OpenGL is a programming library for writing interactive 3D applications.
See the </a><a href="http://www.opengl.org/">OpenGL website</a> for more
information.
</p>
<p>
Mesa 5.x supports the OpenGL 1.4 specification.
</p>
<h2>1.2 Does Mesa support/use graphics hardware?</h2>
<p>
Yes. Specifically, Mesa serves as the OpenGL core for the open-source
XFree86/DRI OpenGL drivers. See the <a href="http://dri.sf.net/">DRI
website</a> for more information.
</p>
<p>
There have been other hardware drivers for Mesa over the years (such as
the 3Dfx Glide/Voodoo driver, an old S3 driver, etc) but the DRI drivers
are the modern ones.
</p>
<h2>1.3 What purpose does Mesa (software-based rendering) serve today?</h2>
<p>
Hardware-accelerated OpenGL implementations are available for most popular
operating systems today.
Still, Mesa serves at least these purposes:
</p>
<ul>
<li>Mesa is used as the core of the open-source XFree86/DRI hardware drivers.
</li>
<li>Mesa is quite portable and allows OpenGL to be used on systems
that have no other OpenGL solution.
</li>
<li>Software rendering with Mesa serves as a reference for validating the
hardware drivers.
</li>
<li>A software implementation of OpenGL is useful for experimentation,
such as testing new rendering techniques.
</li>
<li>Mesa can render images with deep color channels: 16-bit integer
and 32-bit floating point color channels are supported.
This capability is only now appearing in hardware.
</li>
<li>Mesa's internal limits (max lights, clip planes, texture size, etc) can be
changed for special needs (hardware limits are hard to overcome).
</li>
</ul>
<h2>1.4 How do I upgrade my DRI installation to use a new Mesa release?</h2>
<p>
You don't! A copy of the Mesa source code lives inside the XFree86/DRI source
tree and gets compiled into the individual DRI driver modules.
If you try to install Mesa over an XFree86/DRI installation, you'll lose
hardware rendering (because stand-alone Mesa's libGL.so is different than
the XFree86 libGL.so).
</p>
<p>
The DRI developers will incorporate the latest release of Mesa into the
DRI drivers when the time is right.
</p>
<p>
To upgrade, either look for a new release of <a href="http://www.xfree86.org"
target="_parent">XFree86</a> or visit the
<a href="http://dri.sf.net" target="_parent">DRI website</a> to see
if there's newer drivers.
</p>
<h2>1.5 Are there other open-source implementations of OpenGL?</h2>
<p>
Yes, SGI's <a href="http://oss.sgi.com/projects/ogl-sample/index.html">
OpenGL Sample Implemenation (SI)</a> is available.
The SI was written during the time that OpenGL was originally designed.
Unfortunately, development of the SI has stagnated.
Mesa is much more up to date with modern features and extensions.
</p>
<p>
<a href="http://www.dsbox.com/minigl.html">miniGL</a> is a subset of OpenGL
for PalmOS devices.
<a href="http://fabrice.bellard.free.fr/TinyGL/">TinyGL</a> is another
subset of OpenGL.
</p>
<p>
There may be others but Mesa is the most popular and feature-complete.
</p>
<br>
<br>
<a name="part2">
</a><h1><a name="part2">2. Compilation and Installation Problems</a></h1>
<h2><a name="part2">2.1 What's the easiest way to install Mesa?</a></h2>
<p>
<a name="part2">If you're using a Linux-based system, your distro CD most likely already
has Mesa packages (like RPM or DEB) which you can easily install.
</a></p>
<h2><a name="part2">2.2 Running <code>configure; make</code> Doesn't Work</a></h2>
<p>
<a name="part2">Unfortunately, the GNU autoconf/automake/libtool system doesn't seem to work
too well on non GNU/Linux systems, even after installing gmake, gcc, etc.
For that reason, Mesa's <b>old-style</b> makefile system is still included.
The old-style system uses good old traditional Makefiles. Try the following:
</a></p><pre><a name="part2"> cd Mesa-x.y.z
cp Makefile.X11 Makefile
make
</a></pre>
<a name="part2">You'll see a list of system configurations from which to choose.
For example:
</a><pre><a name="part2"> make linux-x86
</a></pre>
<p>
<a name="part2">If you're experienced with GNU autoconf/automake/libtool and think you can help
with maintence, contact the Mesa developers.
FYI, the Mesa developers generally don't use the autoconf/automake system.
We're especially annoyed with the fact that a +5000-line script (libtool)
is needed to make shared libraries (ugh).
</a></p>
<h2><a name="part2">2.3 Mesa still doesn't compile</a></h2>
<p>
<a name="part2">If the old-style Makefile system doesn't work either, make sure you have
the most recent version of Mesa.
Otherwise, file a bug report or post to the Mesa3d-users mailing list.
Give as much info as possible when describing your problem.
</a></p>
<h2><a name="part2">2.4 I get undefined symbols such as bgnpolygon, v3f, etc...</a></h2>
<p>
<a name="part2">You're application is written in IRIS GL, not OpenGL.
IRIS GL was the predecessor to OpenGL and is a different thing (almost)
entirely.
Mesa's not the solution.
</a></p>
<h2><a name="part2">2.5 Where is the GLUT library?</a></h2>
<p>
<a name="part2">GLUT (OpenGL Utility Toolkit) is in the separate MesaDemos-x.y.z.tar.gz file.
If you don't already have GLUT installed, you should grab the MesaDemos
package and unpack it before compiling Mesa.
</a></p>
<h2><a name="part2">2.6 What's the proper place for the libraries and headers?</a></h2>
<p>
<a name="part2">On Linux-based systems you'll want to follow the
</a><a href="http://oss.sgi.com/projects/ogl-sample/ABI/index.html">Linux ABI</a>
standard.
Basically you'll want the following:
</p>
<ul>
<li>/usr/include/GL/gl.h - the main OpenGL header
</li><li>/usr/include/GL/glu.h - the OpenGL GLU (utility) header
</li><li>/usr/include/GL/glx.h - the OpenGL GLX header
</li><li>/usr/include/GL/glext.h - the OpenGL extensions header
</li><li>/usr/include/GL/glxext.h - the OpenGL GLX extensions header
</li><li>/usr/include/GL/osmesa.h - the Mesa off-screen rendering header
</li><li>/usr/lib/libGL.so - a symlink to libGL.so.1
</li><li>/usr/lib/libGL.so.1 - a symlink to libGL.so.1.xyz
</li><li>/usr/lib/libGL.so.xyz - the actual OpenGL/Mesa library. xyz denotes the
Mesa version number.
</li><li>/usr/lib/libGLU.so - a symlink to libGLU.so.1
</li><li>/usr/lib/libGLU.so.1 - a symlink to libGLU.so.1.3.xyz
</li><li>/usr/lib/libGLU.so.xyz - the OpenGL Utility library. xyz denotes the Mesa
version number.
</li></ul>
<p>
After installing XFree86 and the DRI drivers, some of these files
may be symlinks into the /usr/X11R6/ tree.
</p>
<p>
The old-style Makefile system doesn't install the Mesa libraries; it's
up to you to copy them (and the headers) to the right place.
</p>
<p>
The GLUT header and library should go in the same directories.
</p>
<br>
<br>
<a name="part3">
</a><h1><a name="part3">3. Runtime / Rendering Problems</a></h1>
<h2><a name="part3">3.1 Rendering is slow / why isn't my graphics hardware being used?</a></h2>
<p>
<a name="part3">Stand-alone Mesa (downloaded as MesaLib-x.y.z.tar.gz) doesn't have any
support for hardware acceleration (with the exception of the 3DFX Voodoo
driver).
</a></p>
<p>
<a name="part3">What you really want is a DRI or NVIDIA (or another vendor's OpenGL) driver
for your particular hardware.
</a></p>
<p>
<a name="part3">You can run the <code>glxinfo</code> program to learn about your OpenGL
library.
Look for the GL_VENDOR and GL_RENDERER values.
That will identify who's OpenGL library you're using and what sort of
hardware it has detected.
</a></p>
<p>
<a name="part3">If your DRI-based driver isn't working, go to the
</a><a href="http://dri.sf.net/">DRI website</a> for trouble-shooting information.
</p>
<h2>3.2 I'm seeing errors in depth (Z) buffering. Why?</h2>
<p>
Make sure the ratio of the far to near clipping planes isn't too great.
Look
<a href="http://www.sgi.com/software/opengl/advanced97/notes/node18.html">
here</a> for details.
</p>
<p>
Mesa uses a 16-bit depth buffer by default which is smaller and faster
to clear than a 32-bit buffer but not as accurate.
If you need a deeper you can modify the parameters to
<code> glXChooseVisual</code> in your code.
</p>
<h2>3.3 Why Isn't depth buffering working at all?</h2>
<p>
Be sure you're requesting a depth buffered-visual. If you set the MESA_DEBUG
environment variable it will warn you about trying to enable depth testing
when you don't have a depth buffer.
</p>
<p>Specifically, make sure <code>glutInitDisplayMode</code> is being called
with <code>GLUT_DEPTH</code> or <code>glXChooseVisual</code> is being
called with a non-zero value for GLX_DEPTH_SIZE.
</p>
<p>This discussion applies to stencil buffers, accumulation buffers and
alpha channels too.
</p>
<h2>3.4 Why does glGetString() always return NULL?</h2>
<p>
Be sure you have an active/current OpenGL rendering context before
calling glGetString.
</p>
<h2>3.5 GL_POINTS and GL_LINES don't touch the right pixels</h2>
<p>
If you're trying to draw a filled region by using GL_POINTS or GL_LINES
and seeing holes or gaps it's because of a float-to-int rounding problem.
But this is not a bug.
See Appendix H of the OpenGL Programming Guide - "OpenGL Correctness Tips".
Basically, applying a translation of (0.375, 0.375, 0.0) to your coordinates
will fix the problem.
</p>
<br>
<br>
<a name="part4">
</a><h1><a name="part4">4. Developer Questions</a></h1>
<h2><a name="part4">4.1 How can I contribute?</a></h2>
<p>
<a name="part4">First, join the Mesa3d-dev mailing list. That's where Mesa development
is discussed.
</a></p>
<p>
<a name="part4">The </a><a href="http://www.opengl.org/developers/documentation/specs.html">
OpenGL Specification</a> is the bible for OpenGL implemention work.
You should read it.
</p>
<p>Most of the Mesa development work involves implementing new OpenGL
extensions, writing hardware drivers (for the DRI), and code optimization.
</p>
<h2>4.2 How do I write a new device driver?</h2>
<p>
Unfortunately, writing a device driver isn't easy.
It requires detailed understanding of OpenGL, the Mesa code, and your
target hardware/operating system.
3D graphics are not simple.
</p>
<p>
The best way to get started is to use an existing driver as your starting
point.
For a software driver, the X11 and OSMesa drivers are good examples.
For a hardware driver, the Radeon and R200 DRI drivers are good examples.
</p>
<p>The DRI website has more information about writing hardware drivers.
The process isn't well document because the Mesa driver interface changes
over time, and we seldome have spare time for writing documentation.
That being said, many people have managed to figure out the process.
</p>
<p>
Joining the appropriate mailing lists and asking questions (and searching
the archives) is a good way to get information.

<TITLE>Mesa fbdev/DRI Environment</TITLE>
<BODY text="#000000" bgcolor="#55bbff" link="#111188">
<center><H1>Mesa fbdev/DRI Drivers</H1></center>
<H1>1. Introduction</H1>
<p>
The fbdev/DRI sub-project within Mesa brings hardware accelerated OpenGL
rendering to the Linux fbdev environment.
The X Window System / XFree86 is not needed.
</p>
<p>
Basically, the <a href="http://dri.sf.net/">DRI</a> drivers for hardware
accelerated OpenGL for XFree86 have been ported to fbdev so that X is
not needed.
This means fbdev/DRI works in full-screen mode only.
</p>
<p>
DRI driver writers may find this simplified environment easier to work in,
compared to the full XFree86/DRI environment.
</p>
<p>
Much of the work for this project has been done by Jon Smirl and
Keith Whitwell.
</p>
<p>
To use fbdev/DRI, you'll need a Linux 2.4 or 2.6 kernel.
</p>
<p>
The fbdev/DRI Mesa code is in the Mesa CVS trunk (to be released as Mesa
5.1 in the future).
</p>
<h1>2. Compilation</h1>
<p>
Assuming you're starting with a fresh Mesa CVS checkout, do the following:
</p>
<pre>
cd Mesa-newtree
cp Makefile.X11 Makefile # or use a symlink
make linux-solo
</pre>
<p>
When this is finished, check the <code>Mesa-newtree/lib</code> directory
to verify that the following files were made:
</p>
<ul>
<li><code>libGL.so.1.2</code> - the client-side OpenGL library
(and a few symlinks to it).
<li><code>libGLU.so.1.1</code> - the GLU library (and a few symlinks to it).
<li><code>libglut.so.3.7</code> - the GLUT library (and a few symlinks to it).
<li><code>mga_dri.so</code> - DRI driver for Matrox G200/G400 cards.
<li><code>r128_dri.so</code> - DRI driver for ATI Rage 128 cards.
<li><code>r200_dri.so</code> - DRI driver for ATI R200 Radeon cards.
<li><code>radeon_dri.so</code> - DRI driver for original ATI Radeon cards.
<li><code>fb_dri.so</code> - software-only fbdev driver.
<li><code>miniglx.conf</code> - configuration file for the MiniGLX interface
</ul>
<h1>3. Using fbdev/DRI</h1>
<p>
If XFree86 is currently running, exit/stop the X server so you're
working from the console.
</p>
<h2>3.1 Kernel Modules</h2>
<p>
You'll need to load kernel modules specific to your graphics hardware.
The following kernel modules should be included with your kernel.
</p>
<p>
If you have ATI Radeon/R200 hardware, run as root:
</p>
<pre>
modprobe agpgart # the AGP GART module
modprobe radeonfb # the Radeon fbdev driver
modprobe radeon # the Radeon DRI kernel module
</pre>
<p>
If you have ATI Rage 128 hardware, run as root:
</p>
<pre>
modprobe agpgart # the AGP GART module
modprobe aty128fb # the Rage 128 fbdev driver
modprobe r128 # the Rage 128 DRI kernel module
</pre>
<p>
If you have Matrox G200/G400 hardware, run as root:
</p>
<pre>
modprobe agpgart # the AGP GART module
modprobe mgafb # the Matrox fbdev driver
modprobe mga # the Matrox DRI kernel module
</pre>
<p>
Then run <code>lsmod</code> to be sure the modules are loaded.
For a Radeon card, you should see something like this:
</p>
<pre>
Module Size Used by Not tainted
radeon 110308 0 (unused)
radeonfb 21900 0 (unused)
agpgart 43072 1
</pre>
<h2>3.2 Configuration File</h2>
<p>
The <code>Mesa-newtree/lib/miniglx.conf</code> file should be installed
in <code>/etc/</code>.
</p>
<p>
Edit <code>/etc/miniglx.conf</code> to be sure it's set up correctly
for your hardware.
Comments in the file explain the options.
</p>
<h2>3.3 Running fbdev/DRI Programs</h2>
<p>
Make sure your LD_LIBRARY_PATH environment variable is set to the
<code>Mesa-newtree/lib/</code> directory.
</p>
<p>
Change to the <code>Mesa-newtree/progs/miniglx/</code> directory and
start the sample_server program in the background:
</p>
<pre>
./sample_server &
</pre>
<p>
Then try running the <code>miniglxtest</code> program:
</p>
<pre>
./miniglxtest
</pre>
<p>
You should see a rotating quadrilateral which changes color as it rotates.
It will exit automatically after a bit.
</p>
<p>
If you run other tests in the miniglx/ directory, you may want to run
them from a remote shell so that you can stop them with ctrl-C.
</p>
<h1>4.0 Troubleshooting</h1>
<p>
If you try to run miniglxtest and get the following:
</p>
<pre>
[miniglx] failed to probe chipset
connect: Connection refused
server connection lost
</pre>
<p>
It means that the sample_server process is not running.
</p>
<h1>5.0 Programming Information</h1>
<p>
The full OpenGL API is available with fbdev/DRI.
</p>
<p>
OpenGL/Mesa is interfaced to fbdev via the <a href="MiniGLX.html">MiniGLX</a>
interface.
MiniGLX is a subset of Xlib and GLX API functions which provides just
enough functionality to setup OpenGL rendering and respond to simple
input events.
</p>
<p>
Since MiniGLX is a subset of the usual Xlib and GLX APIs, programs written
to the MiniGLX API can also be run on full Xlib/GLX implementations.
This allows some degree of flexibility for software development and testing.
</p>
<p>
However, the MiniGLX API is not binary-compatible with full Xlib/GLX.
Some of the structures are different and some macros/functions work
differently.
See the <code>GL/miniglx.h</code> header file for details.

<BODY text="#000000" bgcolor="#55bbff" link="#111188">
<H1>SGI SI GLU</H1>
(Silicon Graphics, Inc. Sample Implementation of the OpenGL Utility library)
<p>
SGI open-sourced their OpenGL Sample Implementation (SI) in January, 2000.
This includes the GLU library.
</p>
<p>
The SI GLU library implements GLU version 1.3 whereas the original
Mesa GLU library only implemented version 1.2.
We recommend using the SI GLU library instead of Mesa's GLU library
since it's more up-to-date, complete and reliable.
We're no longer developing the original Mesa GLU library.
</p>
<p>
The new SI GLU library code is included in the Mesa package.
You don't have to download it separately.
</p>
<p>
<b>Olivier Michel</b> has made Linux RPMs of GLU for i386 and PowerPC.
You can download them from the
<a href="http://www.sourceforge.net/project/showfiles.php?group_id=3"
target="_parent">download area</a> under <b>Miscellaneous</b>.
</p>
<p>
Visit the <a href="http://oss.sgi.com/projects/ogl-sample/" target="_parent">

<H1>Help Wanted</H1>
<p>
We can always use more help with the Mesa project. Here are some
specific areas. If you think you can help out, post to the mesa3d-dev
mailing list.
</p>
<ul>
<li>Windows 98/NT build/driver maintenance and testing (Karl Schultz has been
doing a great job of this lately)
<li>DOS/DJGPP build/driver maintenance and testing
<li>GGI driver/build maintenance and testing
<li>GNU autoconfig/libtool maintenance (esp. on non-Linux systems)
<li>x86, SSE, 3DNow! and SPARC assembly language programming
<li>Implement WGL font functions in the WGL interface code
<li>Implement off-screen bitmap rendering support in the WGL interface code
<li>Help with writing/testing the new NV_fragment_program extension code
<li>Implement the ARB_vertex/fragment extensions
<li>Download/compile/test Mesa and report any bugs found
</ul>
<p>
If you want to help with Mesa, first join the Mesa developer's
mailing list. Then post a message explaining what you might like
to help with. The Mesa web page has a list of a few work items
which you may consider.
</p>
</p>
Anyone is welcome to contribute code to the Mesa project, provided you
agree to the copyright terms of the relevant code. See the COPYRIGHT
file.
</p>
<p>
Unfortunately, all the easy work in Mesa was done years ago. Nowadays, the
work is rather complicated and not suited to beginners.
</p>
<p>
If you're contribution code to the Mesa library itself:
<p>
<ol>
<li>Try to write clean code (uniform indentation, comments, meaningful
identifiers, etc). It must be readable and maintainable!
<li>Test your code. On several occations I've incorporated code from
users which later turned out to have bugs. Now, I'm pretty hesitant
to use code which doesn't look good.

<H2>1. Unix/X11 Compilation and Installation</H1>
<p>
Mesa uses a rather conventional Makefile system.
A GNU autoconf/automake system used to be included, but was discarded
in Mesa 5.1 because:
</p>
<ul>
<li>It seldom worked on IRIX, Solaris, AIX, etc.
<li>It was very compilicated
<li>Nobody maintained it
<li>libtool was just too weird
</ul>
<p>
If someone strongly feels that Mesa should have a autoconf/automake
system and wants to contribute one and maintain it, we'll consider
adding it again.
</p>
<h3>1.1 Compilation</h3>
<p>
If you've obtained Mesa through CVS, do this to first:
</p>
<pre>
cd Mesa-newtree
cp Makefile.X11 Makefile
</pre>
<p>
Now, just type <b>make</b>.
You'll see a list of supported system configurations.
Choose one from the list (such as linux-x86), and type:
</p>
<pre>
make linux-x86
</pre>
<p>
That's it.
</p>
<h3>1.2 The libraries</h3>
<p>
When compilation has finished, look in the top-level <b>lib/</b> directory.
You'll see a set of library files similar to this:
</p>
<pre>
lrwxrwxrwx 1 brian users 10 Sep 4 17:55 libGL.so -> libGL.so.1*
lrwxrwxrwx 1 brian users 19 Sep 4 17:55 libGL.so.1 -> libGL.so.1.4.050100*
-rwxr-xr-x 1 brian users 13940317 Sep 4 17:55 libGL.so.1.4.050100*
lrwxrwxrwx 1 brian users 11 Sep 4 17:54 libGLU.so -> libGLU.so.1*
lrwxrwxrwx 1 brian users 20 Sep 4 17:54 libGLU.so.1 -> libGLU.so.1.3.050100*
-rwxr-xr-x 1 brian users 324746 Sep 3 13:54 libGLU.so.1.1*
-rwxr-xr-x 1 brian users 2830539 Sep 4 17:54 libGLU.so.1.3.050100*
lrwxrwxrwx 1 brian users 12 Sep 4 17:53 libglut.so -> libglut.so.3*
lrwxrwxrwx 1 brian users 16 Sep 4 17:53 libglut.so.3 -> libglut.so.3.7.1*
-rwxr-xr-x 1 brian users 2426683 Sep 4 17:53 libglut.so.3.7.1*
</pre>
<p>
<b>libGL</b> is the main OpenGL library (i.e. Mesa).
<br>
<b>libGLU</b> is the OpenGL Utility library.
<br>
<b>libglut</b> is the GLUT library.
</p>
<h3>1.3 Running the demos</h3>
<p>
If you downloaded/unpacked the MesaDemos-x.y.z.tar.gz archive or
obtained Mesa from CVS, the <b>progs/</b> directory will contain a
bunch of demonstration programs.
</p>
<p>
Before running a demo, you may have to set an environment variable
(such as <b>LD_LIBRARY_PATH</b> on Linux) to indicate where the
libraries are located. For example:
<p>
<blockquote>
<b>cd</b> into the Mesa <b>lib/</b> directory.
<br>
<b>setenv LD_LIBRARY_PATH ${cwd}</b> (if using csh or tcsh shell)
<br>
or,
<br>
<b>export LD_LIBRARY_PATH=${PWD}</b> (if using bash or sh shell)
</blockquote>
<p>
Next, change to the Mesa/demos/ directory:
</p>
<blockquote>
<b>cd ../progs/demos</b>
</blockquote>
<p>
Run a demo such as gears:
</p>
<blockquote>
<b>./gears</b>
</blockquote>
<p>
If this doesn't work, try the <b>Mesa/progs/xdemos/glxinfo</b> program
and see that it prints the expected Mesa version number.
</p>
<p>
If you're using Linux or a similar OS, verify that the demo program is
being linked with the proper library files:
</p>
<blockquote>
<b>ldd gears</b>
</blockquote>
<p>
You should see something like this:
</p>
<pre>
libglut.so.3 => /home/brian/Mesa/lib/libglut.so.3 (0x40013000)
libGLU.so.1 => /home/brian/Mesa/lib/libGLU.so.1 (0x40051000)
libGL.so.1 => /home/brian/Mesa/lib/libGL.so.1 (0x400e0000)
libc.so.6 => /lib/i686/libc.so.6 (0x42000000)
libm.so.6 => /lib/i686/libm.so.6 (0x403da000)

libXi.so.6 => /usr/X11R6/lib/libXi.so.6 (0x40543000)
libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x4054b000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x405fd000)
libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x40605000)
libpthread.so.0 => /lib/i686/libpthread.so.0 (0x40613000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
libdl.so.2 => /lib/libdl.so.2 (0x40644000)

libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x40650000)
</pre>
<p>
Retrace your steps if this doesn't look right.
</p>
<H3>1.4 Installing the header and library files</H3>
<p>
The standard location for the OpenGL header files on Unix-type systems is
in <code>/usr/include/GL/</code>.
The standard location for the libraries is <code>/usr/lib/</code>.
For more information see, the
<a href="http://oss.sgi.com/projects/ogl-sample/ABI/" target="_parent">
Linux/OpenGL ABI specification</a>.
</p>
<p>
If you'd like Mesa to co-exist with another implementation of OpenGL that's
already installed, you'll have to choose different directories, like
<code>/usr/local/include/GL/</code> and <code>/usr/local/lib/</code>.
</p>
<p>
To install the Mesa headers, do this:
<blockquote>
<b>cp -r include/GL /usr/include</b>
</blockquote>
<p>
To install the Mesa libraries, do this:
</p>
<blockquote>
<b>cp -pd lib/* /usr/lib</b>
<br>
(The -pd options preserve symbolic links)
</blockquote>
<p>
If you install the libraries in a non-standard location you can use
LD_LIBRARY_PATH (on Linux) to switch between the Mesa libs and another
vendor libs whenever you want.
This is a handy way to compare multiple OpenGL implementations.

<TITLE>Mesa Introduction</TITLE>
<BODY text="#000000" bgcolor="#55bbff">
<H1>Introduction</H1>
<p>
Mesa is a 3-D graphics library with an API which is very similar to
that of <a href="http://www.opengl.org/" target="_parent">OpenGL</a>.*
To the extent that Mesa utilizes the OpenGL command syntax or state
machine, it is being used with authorization from <a
href="http://www.sgi.com/" target="_parent">Silicon Graphics,
Inc.</a>(SGI). However, the author does not possess an OpenGL license
from SGI, and makes no claim that Mesa is in any way a compatible
replacement for OpenGL or associated with SGI. Those who want a
licensed implementation of OpenGL should contact a licensed
vendor.
</p>
<p>
Please do not refer to the library as <em>MesaGL</em> (for legal
reasons). It's just <em>Mesa</em> or <em>The Mesa 3-D graphics
library</em>. <br>
</p>
<p>
* OpenGL is a trademark of <a href="http://www.sgi.com/"
target="_parent">Silicon Graphics Incorporated</a>.
</p>
<H1>Project History</H1>
<p>
The Mesa project was founded by me, Brian Paul. Here's a short history
of the project.
</p>
<p>
August, 1993: I begin working on Mesa in my spare time. The project
has no name at that point. I was simply interested in writing a simple
3D graphics library that used the then-new OpenGL API. I was partially
inspired by the <em>VOGL</em> library which emulated a subset of IRIS GL.
I had been programming with IRIS GL since 1991.
</p>
<p>
November 1994: I contact SGI to ask permission to distribute my OpenGL-like
graphics library on the internet. SGI was generally receptive to the
idea and after negotiations with SGI's legal department, I get permission
to release it.
</p>
<p>
February 1995: Mesa 1.0 is released on the internet. I expected that
a few people would be interested in it, but not thousands.
I was soon receiving patches, new features and thank-you notes on a
daily basis. That encouraged me to continue working on Mesa. The
name Mesa just popped into my head one day. SGI had asked me not to use
the terms <em>"Open"</em> or <em>"GL"</em> in the project name and I didn't
want to make up a new acronym. Later, I heard of the Mesa programming
language and the Mesa spreadsheet for NeXTStep.
</p>
<p>
In the early days, OpenGL wasn't available on too many systems.
It even took a while for SGI to support it across their product line.
Mesa filled a big hole during that time.
For a lot of people, Mesa was their first introduction to OpenGL.
I think SGI recognized that Mesa actually helped to promote
the OpenGL API, so they didn't feel threatened by the project.
</p>
<p>
1995-1996: I continue working on Mesa both during my spare time and during
my work hours at the Space Science and Engineering Center at the University
of Wisconsin in Madison. My supervisor, Bill Hibbard, lets me do this because
Mesa is now being using for the <a href="http://www.ssec.wisc.edu/%7Ebillh/vis.html" target="_parent">Vis5D</a> project.
</p><p>
October 1996: Mesa 2.0 is released. It implementes the OpenGL 1.1 specification.
</p>
<p>
March 1997: Mesa 2.2 is released. It supports the new 3dfx Voodoo graphics
card via the Glide library. It's the first really popular hardware OpenGL
implementation for Linux.
</p>
<p>
September 1998: Mesa 3.0 is released. It's the first publicly-available
implementation of the OpenGL 1.2 API.
</p>
<p>
March 1999: I attend my first OpenGL ARB meeting. I contribute to the
development of several official OpenGL extensions over the years.
</p>
<p>
September 1999: I'm hired by Precision Insight, Inc. Mesa is a key
component of 3D hardware acceleration in the new DRI project for XFree86.
Drivers for 3dfx, 3dLabs, Intel, Matrox and ATI hardware soon follow.
</p>
<p>
October 2001: Mesa 4.0 is released.
It implements the OpenGL 1.3 specification.
</p>
<p>
November 2001: I cofound <a href="http://www.tungstengraphics.com" target="_parent">
Tungsten Graphics, Inc.</a> with Keith Whitwell, Jens Owen, David Dawes and
Frank LaMonica.
I continue to develop Mesa as part of my resposibilities with Tungsten
Graphics and as a spare-time project.
</p>
<p>
November 2002: Mesa 5.0 is released.
It implements the OpenGL 1.4 specification.
</p>
<p>
Ongoing: Mesa is used as the core of many hardware OpenGL drivers for XFree86
within the
<A href="http://dri.sourceforge.net/" target="_parent">DRI project</A>.
I continue to enhance Mesa with new extensions and features.
</p>

<TITLE>Function Name Mangling</TITLE>
<BODY text="#000000" bgcolor="#55bbff" link="#111188">
<H1>Function Name Mangling</H1>
<p>
If you want to use Mesa and native OpenGL in the same application at
the same time you may find it useful to compile Mesa with
<i>name mangling</i>.
This results in all the Mesa functions being prefixed with
<b>mgl</b> instead of <b>gl</b>.
</p>
<p>
To do this, recompile Mesa with the compiler flag -DUSE_MGL_NAMESPACE.
Add the flag to the other compiler flags in Make-config (if using the
old-style build system) or in src/Makefile if using GNU autoconf/
automake to build Mesa.

<TITLE>Off-screen Rendering</TITLE>
<BODY text="#000000" bgcolor="#55bbff" link="#111188">
<H1>Off-screen Rendering</H1>
<p>
Mesa 1.2.4 introduced off-screen rendering, a facility for generating
3-D imagery without having to open a window on your display. Mesa's
simple off-screen rendering interface is completely operating system
and window system independent so programs which use off-screen
rendering should be very portable. This feature effectively
enables you to use Mesa as an off-line, batch-oriented renderer.
</p>
<p>
The "OSMesa" API provides 3 functions for making off-screen
renderings: OSMesaCreateContext(), OSMesaMakeCurrent(), and
OSMesaDestroyContext(). See the Mesa/include/GL/osmesa.h header for
more information. See the demos/osdemo.c file for an example program.
There is no facility for writing images to files. That's up to you.
</p>
<p>
If you want to generate large images (larger than 1280x1024) you'll
have to edit the src/config.h file to change MAX_WIDTH and MAX_HEIGHT
then recompile Mesa. Image size should only be limited by available
memory.
</p>
<H2>Deep color channels</H2>
<p>
For some applications 8-bit color channels don't have sufficient
accuracy (film and IBR, for example). If you're in this situation
you'll be happy to know that Mesa supports 16-bit and 32-bit color
channels through the OSMesa interface. When using 16-bit channels,
channels are GLushorts and RGBA pixels occupy 8 bytes. When using 32-bit
channels, channels are GLfloats and RGBA pixels occupy 16 bytes.
</p>
<p>
To build Mesa/OSMesa with 16-bit color channels:
<pre>
cd Mesa-5.x/src
make -f Makefile.X11 clean
make -f Makefile.OSMesa16 linux-osmesa16
</pre>
For 32-bit channels:
<pre>
cd Mesa-5.x/src
make -f Makefile.X11 clean
make -f Makefile.OSMesa16 linux-osmesa32
</pre>
<p>
You'll wind up with a library named libOSMesa16.so or libOSMesa32.so.
</p>
<p>
If you're not using Linux, you can easily edit Make-config and add
an appropriate configuration.
</p>
<p>
The Mesa/tests/osdemo16.c file (available via CVS) demonstrates how
to use this feature.
</p>
<p>
BE WARNED: 16 and 32-bit channel support has not been exhaustively
tested and there may be some bugs. However, a number of people have
been using this feature successfully so it can't be too broken.

<TITLE>PBuffer Rendering</TITLE>
<BODY text="#000000" bgcolor="#55bbff" link="#111188">
<H1>PBuffer Rendering</H1>
<p>
Basically, FBconfigs and PBuffers allow you to do off-screen rendering
with OpenGL. The OSMesa interface does basically the same thing, but
fbconfigs and pbuffers are supported by more vendors.
</p>
<p>
PBuffers are getting more use nowadays, though they've actually been
around for a long time on IRIX systems and other workstations.
</p>
<p>
The
<a href="http://oss.sgi.com/projects/ogl-sample/registry/SGIX/fbconfig.txt"
target="_parent">GL_SGIX_fbconfig</a>
and
<a href="http://oss.sgi.com/projects/ogl-sample/registry/SGIX/pbuffer.txt"
target="_parent">
GL_SGIX_pbuffer</a> extensions describe the functionality.
More recently, these extensions have been promoted to ARB extensions (on
Windows at least).
</p>
<p>
The Mesa/progs/xdemos/ directory has some useful code for working
with pbuffers:
</p>
<ul>
<li><b>pbinfo.c</b> - like glxinfo, it prints a list of available
fbconfigs and whether each supports pbuffers.
<li><b>pbutil.c</b> - a few utility functions for dealing with
fbconfigs and pbuffers.
<li><b>pbdemo.c</b> - a demonstration of off-screen rendering with pbuffers.
</ul>
<p>
Mesa 4.1 and later support GL_SGIX_fbconfig and GL_SGIX_pbuffer (software
rendering only).

<TITLE>Performance Tips</TITLE>
<BODY text="#000000" bgcolor="#55bbff" link="#111188">
<H1>Performance Tips</H1>
<p>
Performance tips for software rendering:
</P>
<ol>
<li> Turn off smooth shading when you don't need it (glShadeModel)
<li> Turn off depth buffering when you don't need it.
<li> Turn off dithering when not needed.
<li> Use double buffering as it's often faster than single buffering
<li> Compile in the X Shared Memory extension option if it's supported
on your system by adding -DSHM to CFLAGS and -lXext to XLIBS for
your system in the Make-config file.
<li> Recompile Mesa with more optimization if possible.
<li> Try to maximize the amount of drawing done between glBegin/glEnd pairs.
<li> Use the MESA_BACK_BUFFER variable to find best performance in double
buffered mode. (X users only)
<li> Optimized polygon rasterizers are employed when:
rendering into back buffer which is an XImage
RGB mode, not grayscale, not monochrome
depth buffering is GL_LESS, or disabled
flat or smooth shading
dithered or non-dithered
no other rasterization operations enabled (blending, stencil, etc)
<li> Optimized line drawing is employed when:
rendering into back buffer which is an XImage
RGB mode, not grayscale, not monochrome
depth buffering is GL_LESS or disabled
flat shading
dithered or non-dithered
no other rasterization operations enabled (blending, stencil, etc)
<li> Textured polygons are fastest when:
using a 3-component (RGB), 2-D texture
minification and magnification filters are GL_NEAREST
texture coordinate wrap modes for S and T are GL_REPEAT
GL_DECAL environment mode
glHint( GL_PERSPECTIVE_CORRECTION_HINT, GL_FASTEST )
depth buffering is GL_LESS or disabled
<li> Lighting is fastest when:
Two-sided lighting is disabled
GL_LIGHT_MODEL_LOCAL_VIEWER is false
GL_COLOR_MATERIAL is disabled
No spot lights are used (all GL_SPOT_CUTOFFs are 180.0)
No local lights are used (all position W's are 0.0)
All material and light coefficients are >= zero
<li> XFree86 users: if you want to use 24-bit color try starting your
X server in 32-bit per pixel mode for better performance. That is,
start your X server with
startx -- -bpp 32
instead of
startx -- -bpp 24
<li> Try disabling dithering with the MESA_NO_DITHER environment variable.
If this env var is defined Mesa will disable dithering and the
command glEnable(GL_DITHER) will be ignored.

<H1>Mesa Subset</H1>
<p>
In 2002/2003 Tungsten Graphics was contracted to develop a subset Mesa/Radeon
driver for an embedded environment. The result is a reduced-size DRI driver
for the ATI R200 chip, for use with Linux fbdev rather than XFree86.
</p>
<p>
The specification for this subset can be found
<a href="subset-A.html">here</a>.

<p>
The <a href="MiniGLX.html">MiniGLX specification</a> describes the
interface between fbdev and Mesa.

<H1>Supported Systems and Drivers</H1>
<p>
Mesa was originally designed for Unix/X11 systems and is still best
supported on those systems. All you need is an ANSI C compiler and the
X development environment to use Mesa.
</p>
<p>Others have contributed drivers
for the Amiga, Apple Macintosh, BeOS, NeXT, OS/2, MS-DOS, VMS, Windows
9x/NT, and Direct3D.
</p>
<p>
The following files describe the details for various platforms.
Be warned, some of these files (and drivers) may be very out of date.

<p>
The standard Mesa distribution only supports software-based rendering, with
the exception of the 3Dfx Glide driver.
Information about other hardware support follows.
</p>
<ul>
<li>DRI-based hardware support for 3dfx, Intel, Matrox, ATI with XFree86
<blockquote>
<p>The <a href="http://dri.sourceforge.net/" target="_parent">DRI architecture</a>,
originally developed by Precision Insight, Inc. uses Mesa and
provides hardware acceleration for a number of popular chipsets.<br>
<br>
The DRI is part of XFree86 4.0 and later.
<br><br>
If you download and install XFree86 4.x you do not need to
install Mesa separately. All the important parts of Mesa
will be installed with the rest of XFree86.
</blockquote>
<li>3dfx Voodoo1, Voodoo2, Voodoo Rush, Voodoo Banshee, Voodoo3
<blockquote>
<p>All cards based on these chipsets should work with Linux and
Windows 95 via 3dfx's Glide library.
The Mesa/Glide driver is included with the Mesa distribution.
You'll need to install the Glide header files and runtime library.
</p>
<p>
David Bucciarelli wrote the original 3dfx driver for Mesa.<br>
Daryll Strauss ported Glide to Linux.
</p>
</blockquote>
<li>Matrox G200/G400, nVidia RIVA, ATI Rage Pro, Intel i810 on Linux
<blockquote>
<p>The <a href="http://utah-glx.sourceforge.net/" target="_parent">
Utah GLX project</a>
(no longer active) developed drivers for these chipsets and others.
</blockquote>
<li>Amiga Warp3D
<blockquote>
<p>Amiga systems can support 3D hardware with the Warp3D API.
See <a href="http://www.haage-partner.com/3dworld" target="_parent">here</a>.
</blockquote>
<li>Also see
<blockquote>
<p><a href="http://www.linux3d.org/" target="_parent">www.linux3d.org</a> for
other 3D hardware info for Linux.
</blockquote>
</ul>
<p>
<b><em>Note:</em></b>
If you have NVIDIA hardware in your computer,
you should download and install NVIDIA's OpenGL library. You may
however, want to download Mesa in order to use its GLU and GLUT
libraries, or assorted demo programs.</p>

*
* 1. Call DMesaCreateVisual() to initialize graphics.
* 2. Call DMesaCreateContext() to create a DMesa rendering context.
* 3. Call DMesaCreateBuffer() to define the window.
* 4. Call DMesaMakeCurrent() to bind the DMesaBuffer to a DMesaContext.
* 5. Make gl* calls to render your graphics.
* 6. Use DMesaSwapBuffers() when double buffering to swap front/back buffers.
* 7. Before exiting, destroy DMesaBuffer, DMesaContext and DMesaVisual.
