This new technique in steroscopic projection callibrates each pixel that is projected onto non-planar textured and colored surfaces for view-dependant stereoscopic visualization. The ad-hoc projection opens up the potential for augmented reality environements in virtually any space, removing the need for a dedicated white projection screen or CAVEs. Imagine projecting a virtual corridor on a brick wall that maintains its illusion by removing any distortions caused by texture or color and by visualizing the depth of the corridor stereoscopically as the viewer changes position.
