So I'm trying to figure out some basic mathematical functions to aid me in my quest to build an efficient 3d OpenGl environment to create my game in. Right now, the most important thing I need is to understand Dot Product and Cross product. From there I can learn other things like Frustum Culling (so I can do Oct/Quad tree heiarchy for a 3d terrain, etc), billboarded sprites.... fun stuff like that. My question is, does anyone know where I could get some pre-built functions that deal with these? (In any language at all) I'm good at general logic, but math is my weak spot and these concepts are a huge stumbling block for me.

Have a look at the column 3D Geometry Primer in the : http://www.flipcode.com/articles/

Oh that's right. I forgot how good flipcode was. It has answers to everything! I'll give it a read-through once I have time.
