Detailed Description

general : Vector3 is a class for handling 3D Vectors manipulation.

We made a choose to store only a 3 dimensions vectors to speed up system when we change of view point. A general 3D transformation could be placed in a 4x4 matrix, but some of the coefficients are always null. So that's waste of time.
