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. - -David Bucciarelli (tech.hmw@plus.it) - -Humanware s.r.l. -Via XXIV Maggio 62 -Pisa, Italy -Tel./Fax +39-50-554108 -email: info.hmw@plus.it -www: www-hmw.caribel.pisa.it - - -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.
