  You have a bug in your matrix library. The entire universe has collapsed to (0,0,0).

If God is a programmer, I wonder if he's hit on that kind of bug before. "Whoops, destroyed all of existence! Better start over..."

My experience with 3D engines doesn't extend much beyond an undergrad project I did, but even that was enough to read this list and smile knowingly at a good chunk of it.

That was the best one.

This is the perfect cheatsheet for a question I got during an interview at a major GPU company : "You write an OpenGL program displaying a colourful object, but you get a black screen when you launch it. What could have gone wrong in your code ?". I painfully thought about 3 or 4 of them and am now deeply embarrassed by my lack of imagination.
