That's interesting just for the purposes of Nostalgia Not a bad explanation of raycasting, the sample voxel program was pretty good.

I am not trying to high-jack the thread here, but thought I would add another raycasting tutorial to this to keep them all in one place. Lode has a good tut on raycasting as well as a working C++ demo in source code. It uses his QuickCG library which is quite easy to use and set up.
