ABSTRACT:
A method of displaying a computer generated hologram includes displaying the image as a set of facets that approximated to the true shape of the object to be displayed. Each of these facets is populated with points that together make up the image. The invention provides a number of array structures that allow adjoining facets at different orientations and angles to be populated with point without creating areas around the join of either point overpopulation or point underpopulation, and so results in a higher quality image. The invention is mainly applicable for producing interference base Computer Generated Holograms, but can also be used in other types of 3D display that make up objects from an array of points.
