We propose a glasses-free tabletop 3D display that does not need a very high number of projectors with a static screen. The conventional method reproduces a 360-degree-viewable light field of virtual objects on a round table, but it requires several hundred projectors to display high-quality 3D images. Our novel approach realizes a similar light field using merely 1/12 the number of projectors. Our method inserts two cylindrical mirrors in the projection light paths. The mirrors manipulate the optical paths appropriately and form any directional perspective image from a group of rays sourced from all projectors arranged on a circle.
