Minimal Ray Tracer
Some code to accompany tonight's lecture: a version of Paul Heckbert's Minimal Ray Tracer from Graphics Gems IV.

I've updated the code to do the following:

• compile with GNU C
• output plain PPM
• generate a 1024 by 1024 image instead of the tiny 32-pixel original

If you want to experiment with changing the scene defined in ray.h, you'll probably want to download NetPbm for Windows.
