A three dimensional display apparatus includes a diffraction panel for displaying a computer generated hologram and a look-up table. The look-up table includes a plurality of phase entries corresponding to a plurality of image points within a three dimensional image replay volume of the computer generated hologram. The apparatus further includes one or more processors configured to notionally divide the computer generated hologram into one or more hogels and to calculate diffraction fringe information for at least one of the hogels based on a selection of the phase entries.

Computer generated hologram

A system includes a computer generated hologram (CGH) design plane and a processor capable of representing a three dimensional object. The processor is configured to represent a surface of the three dimensional object by a facet, impose a grid defining a set of nodes upon the facet, and associate object points with each node of the grid. The processor is further configured to orient the facet to include a common global origin in the CGH design plane and displace the object points away from their associated node in a random or pseudo random direction parallel to the CGH design plane.
