The programs are RAY (what you ran the get the above line), RAY2 and DISPLAY. RAY is the ray-tracer proper and expects the name of a file containing the scene ans an argument. RAY2 converts the output of RAY to something that the Amiga will display, and DISPLAY is a cheap hack of a dispay program for the images. If you need more info or want the source, drop me a line.

The above "graphics system" is called DBW_RENDER. It is a ray tracing package written by Dave Wecker on the Commodore Amiga and copyrighted by him, but released with a general public licence. I have reproduced part of the licence below. It is very unfortunate that the little he asked regarding the distribution of the programs is being totally ignored. I believe that after producing and releasing to the public such a nice code, the author's wishes regarding the distribution should be adhered to. If such were the case, you wouldn't be asking such questions. By the way, the original distribution diskette besides including the executables and sources of the ray tracing program, it included documentation and examples. --------------------------------------------------------------------------- DBW_RENDER GENERAL PUBLIC LICENSE Copyright (C) 1987 David B.
