Detailed Description

Perspective projection transformation.

This is a perspective projection from a 3D cartesian coordinate system to a 2D cartesian coordinate system, parametrized by the focal expressed in meters. The projection is along the z axis. The center of the projection is the origin of the 3D frame. The projection plane is in the half-space z<0.
