Abstract:
A method for computing interference fringe patterns of a display object comprised by items and displaying computer generated holograms, comprising the steps of:inputting three-dimensional data of said display object into computer means; classifying or grouping input data and computing a plurality of fringe patterns for each classified or grouped display object; converting said plurality of fringe patterns respectively into a plurality of digital images; decomposing said plurality of digital images into individual bits to form bit images; synthesizing bit images obtained for each classified or grouped display object to produce moving pictures for display; and displaying said moving pictures; wherein computation of fringe patterns is performed by classifying said display object according to an attribute, and computing fringe patterns for each classified or grouped object; and wherein conversion to digital images include a step of selecting an information content according to attributes of said items so as to prepare bit images having a number of attribute bits related to each information content; while generation of moving pictures for display includes a step of assigning bit images for each classified or grouped object by distributing bit images to a plurality of field layers of moving pictures.
