Tracked automultiscopic 3d tabletop display

An autostereoscopic display, comprising:

• a display element projecting autostereoscopic images from a display surface;
• a tracking mechanism tracking locations of a viewer relative to the display surface;
• and
• a controller generating reprojected content for use in operating the display element to display the autostereoscopic images to the viewer via the display surface,
• wherein the reprojected content is generated based on the tracked locations of the viewer, and
• wherein the reprojected content is generated by determining for each pixel of the display element content passing through eye locations determined for the each of the tracked locations of the viewer and remapping previously generated content of a 3D object or scene prior to delivery to each of the pixels of the display element to achieve a predefined pattern of content in viewpoints for a predefined set of fixed camera locations for the display element.

A method for providing a 3D experience without 3D glasses, comprising:

• tracking a location of a viewer relative to a lenticular display surface of a display element;
• determining a set of eye locations for the viewer based on the tracked location, wherein the set of eye locations includes at least four adjacent eye locations determined based on the tracked location of the viewer;
• rendering a virtual 3D scene;
• reprojecting viewpoints of the display element based on each of the eye locations;
• generating display content by interdigitating the rendered virtual 3D scene based on the reprojected viewpoints;
• and
• operating the display element using the display content to provide a 3D object in a space spaced apart from the lenticular display surface.
