Dual Photography
This upcoming SIGGRAPH 2005 paper, "Dual Photography," has been receiving a lot of cite-love on del.icio.us and even Ernie's 3D Pancakes. Enjoy!
"We present a novel photographic technique called dual photography, which exploits Helmholtz reciprocity to interchange the lights and cameras in a scene. With a video projector providing structured illumination, reciprocity permits us to generate pictures from the viewpoint of the projector, even though no camera was present at that location. The technique is completely image-based, requiring no knowledge of scene geometry or surface properties, and by its nature automatically includes all transport paths, including shadows, interreflections and caustics..."
