Detailed Description

The Maths namespace contains mathematical tools useful in three dimensional work. Included are Vector, four-vector (Vector4) and Matrix. OpenGL Matrix interface is way too limited for serious Matrix operations, so I have replaced all modelview and projection Matrix manipulations.

There is not much to say about the methods in the classes - either you are familiar with them or not. Understading some linear algebra helps a great deal.
