For a simple Turner Whitted algorithm I'd suggest reading "An Improved Illumination Model for Shaded Display" written by Whitted. It's in Communications of the ACM, June 1980, Volume 23, Number 6. The paper is pretty good but the actual program, which is included is a bit awkward. It was originally written in Pascal & had been translated to C just before its publication. Does anyone know of any comprehensive papers on particle systems (especially shading techniques) ? Any help would be appreciated. -thomas williams ---- "Its only a state of mind" pyrnj!vu-vlsi!williams
