The planar perspective transformation used for modelling the camera
motion, was added to the "optical pendulum" WEB page. Some of the
transforms are present in Persistence of Vision, like 3 translations
and 3 rotations. But the "skew" or "shear" angles <Sx,Sy> are not
directly. Thanks for the POV-Ray advance users to have helped on that.
