We are developing a novel display system that physically realizes a sampling of the light field emitted by a three-dimensional scene. An array of projectors, each with a two-dimensional framebuffer, populates the 4D space of the light field. The view of the scene is simultaneously correct for all head positions within a volume. This eliminates the need for head tracking, produces binocular disparities without the need for glasses, and supports any number of viewers. Input to our display could be streamed from a light field sensor [1], or can be efficiently rendered in parallel using a cluster of standard computer graphics pipelines. For static scenes, no run-time rendering is necessary. We demonstrate the feasibility of the approach using a prototype cluster of projectors.
