+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).

+/* Draw test patterns to help determine correct gamma value for a display.
+ When the intensities of the inner squares nearly match the intensities
+ of their frames (from some distance the borders should disappear) then
+ you've found the right gamma value.
+
+ You can set Mesa's gamma values (for red, green and blue) with the
+ MESA_GAMMA environment variable. But only on X windows!
+ For example:
+ setenv MESA_GAMMA 1.5 1.6 1.4
+ Sets the red gamma value to 1.5, green to 1.6 and blue to 1.4.
+ See the main README file for more information.

+ *
+ * Porting it to xlock (the final objective of this code since the moment I
+ * decided to create it) was possible by comparing the original Mesa's gear
+ * demo with it's ported version, so thanks for Danny Sung for his indirect
+ * help (look at gear.c in xlock source tree). NOTE: At the moment this code
+ * was sent to Brian Paul for package inclusion, the XLock Version was not
+ * available. In fact, I'll wait it to appear on the next Mesa release (If you
+ * are reading this, it means THIS release) to send it for xlock package
+ * inclusion). It will probably there be a GLUT version too.
+ *
+ * Thanks goes also to Brian Paul for making it possible and inexpensive
+ * to use OpenGL at home.

+
+POLYHEDRA GENERATION
+
+For the purpose of this program it's not sufficient to know the polyhedra
+vertexes coordinates. Since the morphing algorithm applies a nonlinear
+transformation over the surfaces (faces) of the polyhedron, each face has
+to be divided into smaller ones. The morphing algorithm needs to transform
+each vertex of these smaller faces individually. It's a very time consoming
+task.
+
+In order to reduce calculation overload, and since all the macro faces of
+the polyhedron are transformed by the same way, the generation is made by
+creating only one face of the polyhedron, morphing it and then rotating it
+around the polyhedron center.
+
+What we need to know is the face radius of the polyhedron (the radius of
+the inscribed sphere) and the angle between the center of two adjacent
+faces using the center of the sphere as the angle's vertex.
+
+The face radius of the regular polyhedra are known values which I decided
+to not waste my time calculating. Following is a table of face radius for
+the regular polyhedra with edge length = 1:
+
+ TETRAHEDRON : 1/(2*sqrt(2))/sqrt(3)
+ CUBE : 1/2
+ OCTAHEDRON : 1/sqrt(6)
+ DODECAHEDRON : T^2 * sqrt((T+2)/5) / 2 -> where T=(sqrt(5)+1)/2
+ ICOSAHEDRON : (3*sqrt(3)+sqrt(15))/12
+
+I've not found any reference about the mentioned angles, so I needed to
+calculate them, not a trivial task until I figured out how :)
+Curiously these angles are the same for the tetrahedron and octahedron.
+A way to obtain this value is inscribing the tetrahedron inside the cube
+by matching their vertexes. So you'll notice that the remaining unmatched
+vertexes are in the same straight line starting in the cube/tetrahedron
+center and crossing the center of each tetrahedron's face. At this point
+it's easy to obtain the bigger angle of the isosceles triangle formed by
+the center of the cube and two opposite vertexes on the same cube face.
+The edges of this triangle have the following lenghts: sqrt(2) for the base
+and sqrt(3)/2 for the other two other edges. So the angle we want is:
+ +-----------------------------------------------------------+
+ | 2*ARCSIN(sqrt(2)/sqrt(3)) = 109.47122063449069174 degrees |
+ +-----------------------------------------------------------+
+For the cube this angle is obvious, but just for formality it can be
+easily obtained because we also know it's isosceles edge lenghts:
+sqrt(2)/2 for the base and 1/2 for the other two edges. So the angle we
+want is:
+ +-----------------------------------------------------------+
+ | 2*ARCSIN((sqrt(2)/2)/1) = 90.000000000000000000 degrees |
+ +-----------------------------------------------------------+
+For the octahedron we use the same idea used for the tetrahedron, but now
+we inscribe the cube inside the octahedron so that all cubes's vertexes
+matches excatly the center of each octahedron's face. It's now clear that
+this angle is the same of the thetrahedron one:
+ +-----------------------------------------------------------+
+ | 2*ARCSIN(sqrt(2)/sqrt(3)) = 109.47122063449069174 degrees |
+ +-----------------------------------------------------------+
+For the dodecahedron it's a little bit harder because it's only relationship
+with the cube is useless to us. So we need to solve the problem by another
+way. The concept of Face radius also exists on 2D polygons with the name
+Edge radius:
+ Edge Radius For Pentagon (ERp)
+ ERp = (1/2)/TAN(36 degrees) * VRp = 0.6881909602355867905
+ (VRp is the pentagon's vertex radio).
+ Face Radius For Dodecahedron
+ FRd = T^2 * sqrt((T+2)/5) / 2 = 1.1135163644116068404
+Why we need ERp? Well, ERp and FRd segments forms a 90 degrees angle,
+completing this triangle, the lesser angle is a half of the angle we are
+looking for, so this angle is:
+ +-----------------------------------------------------------+
+ | 2*ARCTAN(ERp/FRd) = 63.434948822922009981 degrees |
+ +-----------------------------------------------------------+
+For the icosahedron we can use the same method used for dodecahedron (well
+the method used for dodecahedron may be used for all regular polyhedra)
+ Edge Radius For Triangle (this one is well known: 1/3 of the triangle height)
+ ERt = sin(60)/3 = sqrt(3)/6 = 0.2886751345948128655
+ Face Radius For Icosahedron
+ FRi= (3*sqrt(3)+sqrt(15))/12 = 0.7557613140761707538
+So the angle is:
+ +-----------------------------------------------------------+
+ | 2*ARCTAN(ERt/FRi) = 41.810314895778596167 degrees |
+ +-----------------------------------------------------------+

+ * 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.

+ * Demo of a reflective, texture-mapped surface with OpenGL.
+ * Brian Paul August 14, 1995 This file is in the public domain.
+ *
+ * Hardware texture mapping is highly recommended!
+ *
+ * The basic steps are:
+ * 1. Render the reflective object (a polygon) from the normal viewpoint,
+ * setting the stencil planes = 1.
+ * 2. Render the scene from a special viewpoint: the viewpoint which
+ * is on the opposite side of the reflective plane. Only draw where
+ * stencil = 1. This draws the objects in the reflective surface.
+ * 3. Render the scene from the original viewpoint. This draws the
+ * objects in the normal fashion. Use blending when drawing
+ * the reflective, textured surface.
+ *
+ * This is a very crude demo. It could be much better.

+ * GLUT demonstration of texturing with specular highlights.
+ *
+ * When drawing a lit, textured surface one usually wants the specular
+ * highlight to override the texture colors. However, OpenGL applies
+ * texturing after lighting so the specular highlight is modulated by
+ * the texture.
+ *
+ * The solution here shown here is a two-pass algorithm:
+ * 1. Draw the textured surface without specular lighting.
+ * 2. Enable blending to add the next pass:
+ * 3. Redraw the surface with a matte white material and only the
+ * specular components of light sources enabled.
