-INTRODUCTION
-------------
-
-This directory is usually included in the Mesa demos distribution or
-in the GLUT distribution.
-
-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).
