This is basically vectors and matrices.
The matrices for the different transforms and a basic explanation of how they
work is here, but it won't tell you the basics of matrix math like multiplying
etc: http://davidf.faricy.net/povre.html#Matrices (nothing like a little website
promotion)
If you don't know about matrix math tell me and I'll explain a little.
