In possibly the first semi-halfway-decent (yet rather hard) machine problem at U of I, I had to make a program which would let a user control a camera walkthrough of a given terrain in 3D. For example, you can load up a nice old tiff of the Grand Canyon and pretend you’re really there. It’s pretty nice, if I do say so myself. With real-time lighting effects, texture mapping, and wireframing capabilities, it sounds cool despite being lame.
Check it out if you’re so inclined. Me? I’m going home.
