This program started out as a project for a the graduate graphics class (ECS-275) for Nelson Max at U.C. Davis, in 1993. Over the following few years, I sometimes would go back and add features or fix things. The last time I looked at the code was around the Fall of 1995. I don't have any more plans to develop the program, but you can send me email if you're interested in the code.

• Compiles under UNIX or Amiga (Aztec C)
• Parallel processing under UNIX. This works by dynamically farming chunks of scanlines to other computers on the network and automatically collecting them into a final image.
• Anti-aliasing through stochasitc sampling or super-sampling
• Full CSG. Scene definition files use a lisp-like format to describe CSG tree objects and their attributes.
• Each ray's RGB components may be refracted according to their wavelength to produce rainbow effects in materials.
• 3D marble and checkerboard textures
• Bump-mapped waves and ripples.
• Depth of ray-tracing recursion is user-definable, or can terminate when a ray's contribution to a pixel reaches a threshold.

• I plan to post more if I get time (11/21/97)
