Claim:
1. An apparatus for displaying three dimensional (3D) images to a viewer, comprising: a display element with a lenticular display surface, wherein the lenticular display surface is horizontal and facing upward into a viewing space; a location tracking element tracking a location of a viewer in the viewing space relative to the lenticular display surface; a display controller generating reprojected content for use in operating the display element to display 3D images to the viewer via the lenticular display surface, wherein the reprojected content is generated from a digital 3D scene and is based on a set of eye locations determined based on the location of the viewer in the viewing space; a second location tracking element tracking a location of a second viewer in a second viewing space on a side of the lenticular display surface opposite the viewing space; and a backlight assembly operating to provide first and second backlighting to the display element in a time multiplexed manner, wherein the first backlighting is projected through the lenticular display surface to the viewing space and the second backlight is projected through the lenticular display surface to the second viewing space, wherein the display controller generates second reprojected content for use in operating the display element to display 3D images to the second viewer via the lenticular display surface, wherein the second reprojected content is generated from the digital 3D scene and is based on a set of eye locations determined based on the location of the second viewer in the second viewing space, and wherein the backlight assembly comprises directional lighting selectively providing the first and second backlighting through the lenticular display surface with angular offsets of at least 30 degrees.
