Abstract
An improved methof of producing an interference based computer generated hologram (CGH), where the angle dependent and angle independent components of light emanating from point sources of light on a virtual 3D object are calculated separately. This allows the angle independent components to be calculated only once per point source of light, but enables the angle dependent components to be calculated on a each point source of light to each CGH pixel basis. This method reduces the number of calculations required to produce a CGH, thus reducing computational load, but fully retains the image quality of the 3D image.
