GLX 1.0 or later is required.
Overview
Since Mesa allows RGB rendering into drawables with PseudoColor,
StaticColor, GrayScale and StaticGray visuals, Mesa needs a colormap
in order to compute pixel values during rendering.
The colormap associated with a window can be queried with normal
Xlib functions but there is no colormap associated with pixmaps.
The glXCreateGLXPixmapMESA function is an alternative to glXCreateGLXPixmap
which allows specification of a colormap.

Additions to Chapter 3 of the GLX 1.3 Specification (Functions and Errors)
Add to section 3.4.2 Off Screen Rendering
The Mesa implementation of GLX allows RGB rendering into X windows and
pixmaps of any visual class, not just TrueColor or DirectColor. In order
to compute pixel values from RGB values Mesa requires a colormap.
The function
GLXPixmap glXCreateGLXPixmapMESA( Display *dpy, XVisualInfo *visual,
Pixmap pixmap, Colormap cmap );
allows one to create a GLXPixmap with a specific colormap. The image
rendered into the pixmap may then be copied to a window (which uses the
same colormap and visual) with the expected results.
GLX Protocol
None since this is a client-side extension.

GLX 1.0 or later is required.
Overview
Mesa's implementation of GLX is entirely implemented on the client side.
Therefore, Mesa cannot immediately detect when an X window or pixmap is
destroyed in order to free any ancilliary data associated with the window
or pixmap.
The glxMesaReleaseBuffers() function can be used to explicitly indicate
when the back color buffer, depth buffer, stencil buffer, and/or accum-
ulation buffer associated with a drawable can be freed.

Additions to Chapter 3 of the GLX 1.3 Specification (Functions and Errors)
The function
Bool glXReleaseBuffersMESA( Display *dpy, GLXDrawable d );
causes all software ancilliary buffers (back buffer, depth, stencil,
accum, etc) associated with the named drawable to be immediately
deallocated. True is returned if <d> is a valid Mesa GLX drawable,
else False is returned. After calling glXReleaseBuffersMESA, the
drawable should no longer be used for GL rendering. Results of
attempting to do so are undefined.
GLX Protocol
None, since this is a client-side operation.
Errors
None.
New State

The Mesa Glide device driver allows either rendering in full-screen
mode or rendering into an X window. An application can switch between
full-screen and window rendering with the command:
GLboolean glXSet3DfxModeMESA( GLint mode );
<mode> may either be GLX_3DFX_WINDOW_MODE_MESA to indicate window
rendering or GLX_3DFX_FULLSCREEN_MODE_MESA to indicate full-screen mode.
GL_TRUE is returned if <mode> is valid and the operation completed
normally. GL_FALSE is returned if <mode> is invalid or if the Glide
driver is not being used.
Note that only one drawable and context can be created at any given
time with the Mesa Glide driver.

* GGIGLUT contains support for all of the GLUT 3.6 API except for the
high-level primitive drawing functions, but many of the functions (in
particular the menu drawing functions) are just stubs.

I recommend using the GCC-2.95.2/Mingw32.
Greetings,
ftp://ftp.xraylith.wisc.edu/pub/khan/gnu-win32/mingw32/gcc-2.95.2
In order to build the Mingw32 set of Mesa 3-D Graphics Library for Beta3.08
it will be necessary for you to use the Dos or Command Prompt that is available
on most of the i86 based MS Windows machines. Also, I believe that this build
will run on Win95, Win98, WinNT4 and WinNT5.
I haven't tested Win95/98 or WinNT5. This build was generated under
WinNT4 with SP3 installed.
This has not been tested under any systems outside of
a WinNT4 Workstation with EGCS-Mingw32 toolchain, v.1.0.2 installed.
EGCS-Mingw32 uses a variation of gcc to handle its build. The Mesa 3-D
Graphics Library build that I have generated is based, in small part, on the
Cygwin32 build and associated makefiles that Stephane Rehel (rehel@worldnet.fr)
defined back in 1997. The EGCS-Mingw32 toolchain is capable of generating
native windows code and, as of the date of this readme, can be obtained from:
http://www.xraylith.wisc.edu/~khan/software/gnu-win32/egcs-mingw32-102.html
Much thanks to the combined efforts of Mumit Khan, Jan-Jaap Vanderhagen
and Colin Peters for making it possible for the Mingw32 toolchain to exist. Also, thanks go out to Stephane Rehel for the work that was completed on the Cygwin build.
and Colin Peters for making it possible for the EGCS-Mingw32 toolchain to exist.
Installing GCC-2.95.2/Mingw32 Build:
Installing EGCS-Mingw32 Build Revisions:
a) Open the file archive (either tar.gz or .zip extensions)
To install the makefile and source revisions incorporated with this build
of the Mesa 3-D Graphics Library, you'll have to use a version of winzip. I am
in the process of finding a suitable Win32 compatible tar executable so that if
you don't have winzip, you can still decompress the files into their respective
folders/directories.
b) Decide the directory you want to move the archived files to.
a) Move the mingw32.zip file to the top level of the hard drive on your
system.
d) Extract the files from the archive.
e) Edit the mingw32.bat file to accomodate your choice of directory structure.
b) Copy all of the Beta 3.08 src/windows files to the src/ directory.
%mesaroot%: This is your root directory (Mesa-3.3)
%mesasrc%: This is the Mesa-3.3 src directory (Mesa-3.3\src)
%mesalib%: This is where the build will put libGL.a and libGLU.a
b) Open the Winzip file
c) Verify that the files will be properly extracted.
d) Extract the files with the Winzip "Overwrite" and "Use Folder Names"
options enabled.
The zip file directory structure extraction defaults to the top level of
the hard drive where the mingw32.zip file exists unless otherwise instructed by
you.
The version of wmesa.c included with the mingw32 archive needs to replace
the current version of the Beta 3.08 wmesa.c file in order for the egcs-mingw32
build to work. This is because the original Win32 stuff assumes that the glut
utilities are to be installed. The Glut utilities are not part of the
egcs-mingw32 build for Beta 3.08.
Build Considerations:
In order to get the build to work, I needed to create a special makefile
for each library which the Mesa 3-D Graphics Library requires since there is no
comparable make-config/config on a native windows platform.
Since I was only creating a few of the possible libraries for
Mesa (gl, glu), I only created the new make files in their respective libraries
src, src-glu). For libMesaaux.a. you will find a makefile for it in the
src-aux directory. libMesatk.a and libglut.a were not ported.
The build itself is a .bat based build and uses Gnu Make,Version 3.76.1 to
process the makefiles noted above. The build must be run from the directory
where the mingw32.bat file is. You can get the binary version of Make 3.76.1
from Jan-Jaap van der Heijden's site in Germany:
http://agnes.dida.physik.uni-essen.de/~janjaap/mingw32/download.html
It was necessary to modify some source code, specifically the source code
in the src-glu directory. I needed to modify nurbs.c, quadric.c and tess.c in
order to get them to work using the EGCS-Mingw32 toolchain.
The original EGCS-Mingw32 Toolchain, is available from:
http://www.xraylith.wisc.edu/~khan/software/gnu-win32/egcs-mingw32-102.html
Running the Build:
Open your Command Prompt or MS-DOS prompt.
Go to your Mesa-3.3 'root' directory
At the command line type: mingw32
Ok, now that we've got the basics out of the way, follows is all you need
to do in order to build the EGCS-Mingw32 version of libMesaGL.a and libMesaGLU.a:
That's all there is to it.
Open your Command Prompt/Dos prompt.
Go to your Mesa-3.0 beta 'root' directory.
This is the same directory that the Mesa mingw32.zip file was
originally stored in if you've installed the Mesa-3.0 beta 3-D
Graphics Library source as outlined in the "readme" file included
with the Mesa-3.0 beta distribution.
At the command line type: mingw32
mingw32 is the .bat file that actually does the build.
Enjoy!

changes in the Mesa code, the threads support is out of date.
Someone will have to review/update it.
Mesa Threads README
-------------------
Thread safety was introduced in Mesa 2.6 by John Stone and
Christoph Poliwoda.
It was redesigned in Mesa 3.3 so that thread safety is
supported by default (on systems which support threads,
that is). There is no measurable penalty on single
threaded applications.
NOTE that the only _driver_ which is thread safe at this time
is the OS/Mesa driver!
At present the mthreads code supports three thread APIS:
Mesa 2.6 is the starting point for an effort to make Mesa
safe in multithreaded applications. The files src/mthreads.c and
src/mthreads.h provide a platform independent threads API which Mesa
uses internally to provide thread-safe operation. At present the mthreads
code supports three thread APIS:
1) POSIX threads (aka pthreads).
2) Solaris / Unix International threads.
3) Win32 threads (Win 95/NT).
Support for other thread libraries can be added src/glthread.[ch]
Here's the current list of targets which enable multithreaded handling
in Mesa:
linux-386-pthread for Linux w/ Intel assembly and linuxthreads
sunos5-thread for Suns with SunOS 5.x, using Solaris threads
sunos5-pthread for Suns with SunOS 5.[56] using POSIX threads
sunos5-gcc-thread for Suns with SunOS 5.x and GCC, using Solaris threads
sunos5-gcc-pthread for Suns with SunOS 5.[56] and GCC, using POSIX threads
In order to guarantee proper operation, it is
In order to use Mesa with a multithreaded application, Mesa must be compiled
using one of the thread-enabled configurations. In cases where a platform
supports multiple APIs which are acceptable to Mesa, Mesa must be built
with the same threads API as the application in order for things to work
properly. For example, Solaris >= 2.5 support both POSIX threads and
Sun's own threads API. In order to guarantee proper operation, it is
necessary for both Mesa and application code to use the same threads API.
So, if your application uses Sun's thread API, then you should build Mesa
using one of the targets for Sun threads.
Since this effort is still very much a work in progress, not all
aspects of Mesa are thread safe. As of this release (Mesa 2.6) only the
osmesa drivers have been made MT-safe. As work continues, other drivers
such as the X11 drivers will also incorporate MT-safe features.

multiple threads to render to osmesa rendering context(s).

Mesa 3.4.2 Unix/X11 Information
Mesa 3.0 Unix/X11 Information
Installation
============
There are two ways to compile Mesa on Unix/X11 systems:
1. The old way:
First type 'make' alone to see the list of system
configurations currently supported. If you see your configuration on the
list, type 'make <config>'. Most popular Unix/X workstations are currently
supported.
If your system configuration is not listed by 'make', you'll have to modify
the top-level Makefile and Make-config files. There are instructions in
each file.
2. The new way:
Type './configure' and then 'make'. This uses GNU autoconfig.
See docs/INSTALL for more details.
To compile the library, first type 'make' alone to see the list of system
configurations currently supported. If you see your configuration on the
list, type 'make <config>'. Most popular Unix/X workstations are currently
supported.
The top-level makefile will execute the makefiles in a number of sub-
directories. When finished, the Mesa libraries will be in the Mesa-3.3/lib/
directories. When finished, the Mesa libraries will be in the Mesa-2.6/lib/
directory. A few GLUT demos in the demos/ directory should be ready to run.
If you also downloaded and unpacked the demos there should be executables
in the "xdemos/", "samples/", and "book/" directories for you to try out.
If you only want to compile the contents of one subdirectory you can 'cd'
to that directory and type 'make <config>' there.
If your system configuration is not listed by 'make', you'll have to modify
the top-level Makefile and Make-config files. There are instructions in
each file.
If you have compilation problems you should try to fix them and return the
patches to the author.
Notes on assembly language optimizations:
When using the old-style Makefiles, you can specify a configuration
that uses X86 assembly language optimizations (linux-3dnow for example).
The detection of MMX, 3DNow!, PIII/SSE, etc capability is done at
runtime. That means you can compile Mesa for 3DNow! optimizations
even if you don't have an AMD CPU.
However, your Linux binutils and assembler must understand the
special instructions in order to compile them. If you have
compilation problems, try upgrading your binutils.

Mesa 3.1 release notes
PLEASE READ!!!!
New copyright
-------------
Mesa 3.1 will be distributed under an XFree86-style copyright instead
of the GNU LGPL.
New directories
---------------
All documentation files are now in the docs/ directory.
All shell scripts are now in the bin/ directory.
New library names
-----------------
Formerly, the main Mesa library was named libMesaGL.so (or libMesaGL.a)
and the GLU library was named libMesaGLU.so (or libMesaGLU.a).
Now, the main library is named libGL.so (or libGL.a) and the GLU library
is named libGLU.so (or libGLU.a).
The change allows Mesa to be more easily substituted for OpenGL.
Specifically, the linker/loader on some Unix-like systems won't
allow libMesaGL.so to be used instead of libGL.so if the application
was linked with the former.
Warning: if you have another OpenGL implementation installed on your
system (i.e. you have another OpenGL libGL.so) you'll have to be
carefull about which library (OpenGL or Mesa) you link against. Be
aware of -L linker flags and the value of the LD_LIBRARY_PATH environment
variable.
New library versioning
----------------------
Previously, the Mesa GL library was named libMesaGL.so.3.0
To better support Linux/OpenGL standards, the Mesa GL library is now
named libGL.so.1.2.030100 This indicates version 1.2 of the OpenGL spec
and Mesa implementation 3.1.0
In the long term this will allow better interoperability with other
OpenGL implementations, especially on Linux. In the short term,
OpenGL apps may have to be relinked to use the new library naming.
New makefiles
-------------
The old Makefiles found in the various directories have been renamed
to Makefile.X11 in order to prevent filename collisions with autoconfig-
generated Makefiles.
The top-level Makefile simply includes Makefile.X11
If your top-level Makefile get's overwritten/destroyed you can restore
it by copying Makefile.X11 to Makefile
New extensions
--------------
GL_EXT_stencil_wrap
Implements two new stencil operations: GL_INCR_WRAP_EXT and
GL_DECR_WRAP_EXT which allow stencil increment and decrement
without clamping.
GL_INGR_blend_func_separate
Allows specification of blend factors for RGB and Alpha independently.
(INGR = Intergraph)
GL_ARB_multitexture
Multiple simultaneous textures. (ARB = Architecture Review Board)
GL_NV_texgen_reflection
nVidia texgen extension for better reflection mapping.
GL_PGI_misc_hints
Assorted transformation hints.
GL_EXT_compiled_vertex_array
Compiled vertex arrays.
GL_EXT_clip_volume_hint
Allows one to disable clip volume (frustum) testing.
Extensions removed
------------------
GL_EXT_multitexture - obsolete in favor of GL_ARB_multitexture
Config file
-----------
By default, /etc/mesa.conf will be read when Mesa starts. This
file controls default hints, enable/disable of extensions, and
more. See the CONFIG file for documentation.
Optimizations
-------------
Keith Whitwell has contributed significant optimizations to Mesa's
vertex transformation code. Basically, the whole transformation
stage of Mesa has been rewritten.
It's impossible to give a speedup factor. You'll just have to
try your app and see how it performs.
Device Driver changes
---------------------
A bunch of new device driver functions have been added. See src/dd.h
Keith Harrison contributed many of them. I've been planning on adding
a bunch of functions like these to make writing hardware drivers easier.
More such function will probably be added in the near future.
Miscellaneous
-------------
util/glstate.c has some handy functions for debugging. Basically, it
offers a simple function for printing GL state variables. It's not
finished yet. There's a LOT more GLenum records to be added (see the
code). Anyone want to help?

http://oss.sgi.com/projects/ogl-sample/
People are working to make easy-to-install Linux RPMs of the
GLU library.

Mesa 3.3 release notes
July 21, 2000
PLEASE READ!!!!
Introduction
------------
Mesa uses an even/odd version number scheme like the Linux kernel.
Odd numbered versions (such as 3.3) designate new developmental releases.
Even numbered versions (such as 3.2.1) designate stable releases.
Mesa 3.3 has a undergone many internal changes since version 3.2
and features a lot of new extensions. 3.3 is expected to be pretty
stable, but perhaps not as stable as 3.2 which has been used by
thousands of users over the past months.
Everyone is encouraged to try Mesa 3.3. Bugs should be reported to
the Mesa bug database on www.sourceforge.net.
Header file / GLenum changes
----------------------------
The gl.h and glu.h headers now use #defines to define all GL_* tokens
instead of C-language enums. This change improves Mesa/OpenGL
interoperability.
New API dispatch code
---------------------
The core Mesa gl* functions are now implemented with a new dispatch
(jump table) which will allow simultaneous direct/indirect rendering.
The code is found in the glapi*.[ch] files.
Of interest: the actual "glFooBar" functions are generated with
templatized code defined in glapitemp.h and included by glapi.c
The glapitemp.h template should be reusable for all sorts of OpenGL
projects.
The new dispatch code has also optimized with x86 assembly code.
This optimization eliminates copying the function arguments during
dispatch.
New thread support
------------------
Thread support in Mesa has been rewritten. The glthread.[ch] files
replace mthreads.[ch]. Thread safety is always enabled (on platforms
which support threads, that is). There is virtually no performance
penalty for typical single-thread applications. See the glapi.c
file for details.
The Xlib driver (XMesa) is now thread-safe as well. Be sure to
call XInitThreads() in your app first. See the xdemos/glthreads.c
demo for an example.
Make configuration changes
--------------------------
If you use the old-style (non GNU automake) method to build Mesa note
that several of the configuration names have changed:
Old name New name
------------- ----------------
linux-elf linux
linux linux-static
linux-386-elf linux-386
linux-386 linux-386-static
etc.
New extensions
--------------
GL_ARB_transpose_matrix
Adds glLoadTransposeMatrixARB() and glMultTransposeMatrixARB()
functions.
GL_ARB_texture_cube_map
For cube-based reflection mapping.
GL_EXT_texture_add_env
Adds GL_ADD texture environment mode.
See http://www.berkelium.com/OpenGL/EXT/texture_env_add.txt
GL_EXT_texture_lod_bias
Allows mipmapped texture blurring and sharpening.
GLX_EXT_visual_rating extension
This extension has no effect in stand-alone Mesa (used for DRI).
GL_HP_occlusion_test
Used for bounding box occlusion testing (see demos/occlude.c).
GL_SGIX_pixel_texture / GL_SGIS_pixel_texture
Lets glDraw/CopyPixels draw a texture coordinate image.
GL_SGI_color_matrix
Adds a color matrix and another set of scale and bias parameters
to the glDraw/CopyPixels paths.
GL_SGI_color_table
Adds additional color tables to the glDraw/Read/CopyPixels paths.
GL_EXT_histogram
Compute histograms for glDraw/Read/CopyPixels.
GL_EXT_blend_func_separate
This is the same as GL_INGR_blend_func_separate.
GL_ARB_texture_cube_mapping
6-face cube mapping, nicer than sphere mapping
GL_EXT_texture_env_combine
For advanced texture environment effects.
Documentation for all these functions can be found at
http://oss.sgi.com/projects/ogl-sample/registry/
GLX_SGI_make_current_read functionality
---------------------------------------
The functionality of this extension is needed for GLX 1.3 (and required
for the Linux/OpenGL standards base).
Implementing this function required a **DEVICE DRIVER CHANGE**.
The old SetBuffer() function has been replaced by SetReadBuffer() and
SetDrawBuffer(). All device drivers will have to be updated because
of this change.
The new function, glXMakeContextCurrent(), in GLX 1.3 now works in Mesa.
The xdemos/wincopy.c program demonstrates it.
Image-related code changes
--------------------------
The imaging path code used by glDrawPixels, glTexImage[123]D,
glTexSubImage[123], etc has been rewritten. It's now faster,
uses less memory and has several bug fixes. This work was
actually started in Mesa 3.1 with the glTexImage paths but has now
been carried over to glDrawPixels as well.
Device driver interface changes
-------------------------------
Added new functions for hardware stencil buffer support:
WriteStencilSpan
ReadStencilSpan
WriteStencilPixels
ReadStencilPixels
Removed old depth buffer functions:
AllocDepthBuffer
DepthTestSpan
DepthTestPixels
ReadDepthSpanFloat
ReadDepthSpanInt
Added new depth buffer functions:
WriteDepthSpan
ReadDepthSpan
WriteDepthPixels
ReadDepthPixels
These functions always read/write 32-bit GLuints. This will allow
drivers to have anywhere from 0 to 32-bit Z buffers without
recompiling for 16 vs 32 bits as was previously needed.
New texture image functions
The entire interface for texture image specification has been updated.
With the new functions, it's optional for Mesa to keep an internal copy
of all textures. Texture download should be a lot faster when the extra
copy isn't made.
Misc changes
TexEnv now takes a target argument
Removed UseGlobalTexturePalette (use Enable function instead)
Also added
ReadPixels
CopyPixels
The SetBufffer function has been replaced by SetDrawBuffer and
SetReadBuffer functions. This lets core Mesa independently
specify which buffer is to be used for reading and which for
drawing.
The Clear function's mask parameter has changed. Instead of
mask being the flags specified by the user to glClear, the
mask is now a bitmask of the DD_*_BIT flags in dd.h. Now
multiple color buffers can be specified for clearing (ala
glDrawBuffers). The driver's Clear function must also
check the glColorMask glIndexMask, and glStencilMask settings
and do the right thing. See the X/Mesa, OS/Mesa, or FX/Mesa
drivers for examples.
The depth buffer changes shouldn't be hard to make for existing
drivers. In fact, it should simply the code. Be careful with
the depthBits value passed to gl_create_context(). 1 is a bad
value! It should normally be 0, 16, 24, or 32.
gl_create_framebuffer() takes new arguments which explicitly tell
core Mesa which ancillary buffers (depth, stencil, accum, alpha)
should be implemented in software. Mesa hardware drivers should
carefully set these flags depending on which buffers are in the
graphics card.
Internal constants
------------------
Point and line size range and granularity limits are now stored
in the gl_constants struct, which is the Const member of GLcontext.
The limits are initialized from values in config.h but may be
overridden by device drivers to reflect the limits of that driver's
hardware.
Also added constants for NumAuxBuffers and SubPixelBits.
OpenGL Conformance
------------------
Mesa now passes all the OpenGL 1.1 conformance tests, except for
antialiased lines. AA lines fail on some, but not all, the tests.
In order to fix the remaining failures, a new AA line algorithm will
be needed (which computes coverage values for end-point fragments).
This will be done for Mesa 3.5/3.6.
OpenGL 1.2 GL_ARB_imaging subset
--------------------------------
Mesa 3.3 implements all the features of GL_ARB_imaging except for
image convolution. This will (hopefully) be done for Mesa 3.5/3.6.

I have written the demos included in this directory mainly for showing
the capabilities of the Mesa library when using the Voodoo driver.
However all the demos are written using the GLUT and OpenGL so they
work with any GLUT/OpenGL platform (tested: Linux+Mesa+Voodoo driver,
Linux+Mesa+X11 driver, Win95+Mesa+Voodoo driver and SGI Onyx IR thanks
to Mark Kilgard).
All the demos make an heavy use of texture mapping, blending, etc. so
you _need_ some kind of hardware support for the OpenGL otherwise they
will run at ~1fps. You need also a OpenGL 1.1 compliant library.
You can find some screenshot of these demos at
http://www-hmw.caribel.pisa.it/fxmesa/fxdemos.hmtl
Write me if you find some bug in the demos.

A BRIEF DESCRIPTION OF THE DEMOS
--------------------------------
IPERS
-----
Sources: ipers.c image.c
A nice spinning fractal object.
RAY
---
Sources: ray.c
I'm using ray tracing to dynamically generate texture maps with
specular, diffuse, shadows, and mirror colors. Each frame the texture
maps of the plane and of the sphere are partially updated. With this
technique you can obtain true mirrors, shadows, specular highlights,
bump mapping, etc. in realtime. This demo is really CPU intensive
(~25fps on a PentiumII@300MHz with a Pure3D). Support on-the-fly
switching between fullscreen and in-window rendering under Linux/Mesa
(start your X server in 16 bpp mode and press the spacebar).
TUNNEL
------
Sources: tunnel.c image.c sources.c
Data: bw.rgb tile.rgb
The model was designed and prelighted with Alias|Wavefront
PowerAnimator V8. Triangle strips were built with a tool written by me
and then statically included in the sources. This demo doesn't
require the ZBuffer and use antialiased polygons. Support on-the-fly
switching between fullscreen and in-window rendering under Linux/Mesa
(start your X server in 16 bpp mode and press the spacebar).
TUNNEL2
------
Sources: tunnel2.c image.c sources.c
Data: bw.rgb tile.rgb
The some tunnel demo but with two output channels. A nice
example of the Mesa/Voodoo support for multiple boards in
the some PC.
TEAPOT
------
Sources: teapot.c image.c dteapot.c shadow.c
Data: bw.rgb tile.rgb
The shadow is drawn projecting the teapot geometry over the plane. All
other light effects are drawn using the standard OpenGL capabilities.
Support on-the-fly switching between fullscreen and in-window
rendering under Linux/Mesa (start your X server in 16 bpp mode and
press the spacebar).
FIRE
----
Sources: fire.c image.c
Data: s128.rgb tree2.rgb
The demo use a small particle system to draw some nice visual effect.
You can interactively change many parameters of the particle system
and you can choose the number of particles at the startup ('fire
4000'). This demo should be called fountain. Support on-the-fly
switching between fullscreen and in-window rendering under Linux/Mesa
(start your X server in 16 bpp mode and press the spacebar).
TERRAIN
-------
Sources: mesaland.c
This demo is base on another demo written by Mikael SkiZoWalker. I
have added the capabilities to freely fly around, view culling and
some nice color. Support on-the-fly switching between fullscreen and
in-window rendering under Linux/Mesa (start your X server in 16 bpp
mode and press the spacebar).
GLTEST
------
Sources: gltest.c
This is a simple benchmark suite that I'm using in the development of
the Mesa/Voodoo driver. Type 'gltest >my.res' and you will get some
data about the performances of your OpenGL. Follow the results with my
PC (Linux+Mesa-2.6+PentiumII@300MHz+Pure3D):

PALTEX and GLBPALTX
-------------------
Sources: paltex.c and glbpaltx.c
The PALTEX example was written by Brian Paul and it shows the
capabilities of the GL_EXT_paletted_texture extension. I have written
the other example in order to show the capabilities of the
gl3DfxSetPaletteEXT() (it used only by GLQuake and Quake2).

/*
* How this works:
* 1. We load the image into a 2D texture.
* 2. We generate a sequence of RGB images in which the R component
* is really the S texture coordinate and the G component is really
* the T texture coordinate.
* By warping the mapping from R to S and G to T we can get non-linear
* distortions.
* 3. Draw the warped image (a 2-D warping function) with pixel texgen
* enabled.
* 4. Loop over the warped images to animate.
*
* The pixel texgen extension can also be used to do color-space
* conversions. For example, we could convert YCR to RGB with a
* 3D texture map which takes YCR as the S,T,R texture coordinate and
* returns RGB texel values.
*
* You can use this extension in (at least) two ways:
* 1. glDrawPixels w/ color space conversion/warping
* 2. glDrawPixels to spatially warp another image in texture memory
*
* We're basically using glDrawPixels to draw a texture coordinate image.
