Detail
A single projector, projecting a hardware accelerated perspective warped image from an off-axis location. Note the full shadow.

Dual overlapped projectors, auto-calibrated and aligned via camera, in a passive configuration. Note the partial shadow and accurate overlap positioning.

Dual overlapped projectors, actively compensating for shadows. The system currently runs at 14Hz, view the demo movie (below) to get a feeling for the reaction speed.

Dual overlapped projectors, actively compensating for shadows and driving light output on the occluder (my shirt and face) to zero.
