Multiview 3-D photography made simple

Computational photography is the use of clever light-gathering tricks and sophisticated algorithms to extract more information from the visual environment than traditional cameras can. The first commercial application of computational photography is the so-called light-field camera, which can measure not only the intensity of incoming light but also its angle. That information can be used to produce multiperspective 3-D images, or to refocus a shot even after it's been captured.Existing light-fi...
