Detailed Description

template<class T>
class camvox::TVector< T >

A homogenious vector and point class.

A homogenious 3D vector has 4 values: x, y, z, w. The w value can have one of two values; 0.0 means it is a vector, while 1.0 means it is a point.

Both a point and a vector can be multiplied by a 4 x 4 affine Matrix; to be scaled, sheared, rotated and translated (translation only for points). normal 3D points multiplied by a 3 x 3 matrix needed a seperate translation step.

This vector template is compatible with both floating point values and with interval values.
