	)		[static]

Generic camera interfaces (pointer for abstract class).

Solves using back-project so will work for any camera The ray direction assumes the camera is in the positive half-space of the x-y plane. This assumption is necessary since some cameras don't have a natural center of projection (e.g. rational cameras). compute the ray at a given 3-d point.
