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.
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.
