The following was just posted in comp.sources.unix: Submitted-by: Craig Kolb <craig@weedeater.math.yale.edu> Posting-number: Volume 21, Issue 8 Archive-name: rayshade/part01 This is version 3.0 of rayshade, a raytracing program. Rayshade reads a multi-line ASCII file describing a scene to be rendered and produces a Utah Raster RLE format file of the raytraced image. Rayshade features: Eight types of primitives (box, cone, cylinder, height field, polygon, sphere, superquadric, flat- and Phong-shaded triangle) Composite objects Point, directional, and extended (area) light sources Solid procedural texturing and bump mapping of primitives, objects, and individual instances of objects Antialiasing through adaptive supersampling or "jittered" sampling Arbitrary linear transformations on primitives, instances of objects, and texture/bump maps Use of uniform spatial subdivision or hierarchy of bounding volumes to speed rendering Options to facilitate rendering of stereo pairs Support for the C-Linda parallel programming language Rayshade has been tested on many different UNIX-based computers. If your machine has a C compiler and enough memory (at least 2Mb), rayshade should be fairly easy to port. Be warned that rayshade uses yacc and lex to process input files. If you do not have lex and yacc, try to get flex and bison from the Free Software Foundation folks (ftp to prep.ai.mit.edu). Thanks, Craig kolb@yale.edu
