Abstract
In a presently preferred embodiment of the invention, a three-dimensional scene is reproduced on a specialized light display which offers full multiviewpoint capability and auto-stereoscopic views. The displayed image is produced using a set of M two-dimensional images of the scene collected at a set of distinct spatial locations. These M two-dimensional images are processed through a specialized mathematical encoding scheme to obtain a set of N.times.K display-excitation electrical-input signals, where K is the number of pixels in the display, and N.ltoreq.M is the number of individual light-radiating elements within one pixel. The display is thus comprised of a total of N.times.K light-radiating elements. Each of the K pixels is adapted for control of their associated radiance patterns. The display is connected for response to the set of N.times.K display-excitation electrical-input signals. In this manner, the display provides a multiviewpoint and autostereoscopic three-dimensional image associated with the original three-dimensional scene. An alternative embodiment of the invention is utilized to provide efficient storage and display of 3D computer graphics images.
