Pinhole perspective equation NOTE:z is always negative..
Weak-perspective projection is the magnification. When the scene depth is small compared its distance from the Camera, m can be taken constant
Orthographicprojection When the camera is at a (roughly constant) distance from the scene, take m=-1.
