Today I found a good online tutorial on basic 3D math. It’s on an old geocities site that housed the Win 95 Game Programmer’s Encyclopedia. It has what is, for me, the easiest-to-follow explanation of matrix math that I’ve yet found. It’s amazingly concise, and the examples are all very easy to understand – no calculus equations to be found here. Most of the examples are in code. In fact, the author of this website, Mark Feldman, says himself at the beginning of his tutorial on 3D math, “Here’s a secret tip for anyone who has a hard time understanding 3D math: think of it as simply another programming language!”
