Abstract
An apparatus for displaying three dimensional (3D) images to a viewer without the need for 3D glasses. The apparatus includes a display element with a lenticular display surface that is supported to be horizontal and face upward into a viewing space. The apparatus includes a location tracking element tracking a location of a viewer in the viewing space relative to the lenticular display surface. The apparatus includes a display controller generating reprojected content for operating the display element to display 3D images via the lenticular display surface. The reprojected content is generated by determining for each pixel of the display element the content or images passing through tracked and/or determined eye locations and then remapping content delivered to each of the pixels of the display element to achieve a predefined pattern of content in viewpoints of fixed camera positions for the display element.
