Abstract
Abstract A digitized video system having a processor and a video memory. The processor converts a stream of digital information to extract planes of a three dimensional image to store into the video memory to display a three dimensional image. A spatial light modulator is connected to the video memory to receive and display a plane of said image to display a three dimensional image.
