Oblique Projector Rendering onto Planar Surfaces for a Tracked User
 
When projectors create keystoning, a traditional graphics pipeline with a modified projection matrix and an approximation of the z-buffer can be used to create perspectively correct images for a tracked moving user in CAVE or ImmersaDesk.

Projecting Computer Graphics on Moving Surfaces: A Simple Calibration and Tracking Method
 
A simple method of calibrating a camera and a projector so the projected image exactly matches the surface of a moving object. The method is used in the HyperMask system that projects faces on a mask worn by an actor during a performance.
