Detailed Description

Author:

CJP

3x3 Matrix-class. Can be used for all kinds of linear transformations on vectors, and especially for rotations.

The internal storage is 4x4, which makes it easy to use this class in combination with e.g. OpenGL. The fourth row and column are filled like those in a unit matrix.
