glPortal

Recently took a course called Computer Game Programming I: Graphics in which we were required to hand in a simple game-ish program to qualify for the oral exam. Wanted a little more challenge so I decided to make a simple Portal clone.

The actual portals are drawn using the stencil buffer in a pretty straight-forward manner. Unfortunately they are not recursive as I ran out of time. I did however implement some simple per-pixel lighting and normal mapping which was a great exercise in GLSL programming. Would have loved to implement shadow volumes as well, but that's for another time.
