You might like to look at the IRIT package. The source is available on simtel20 and clones in the /msdos/irit directory (apply appropriate dir format). I believe the package started as an X-windows apps (or was at least ported to it at some time), so you might look in the unix-c directory as well. The program is sort of a scientific graphing package. It has 2-d graphs, 3-d wire frames, hidden line removal, and at least shading, if not true raytracing. Lots of neat stuff to look at.
