I'm doing a project for Math, for my Math 11-2 course (G. 11, level 2) and I have decided to do it on 3D Calculations and such. So basically, what I wanted to know, was what types of math's are involved in things like calculating a characters current position, acceleration, direction of motion, things like that. If possible, some (fairly simple) pseudo code would be a great help.

Basically my project is on anything to do with 3D math. Please try to write anything you give me in a way people who know little 3D related math can understand it... (I have to present this in an understandable format )

Thanks everyone!
