Acceleration of the switch-back technique for fast occlusion processing in computer holograph

Abstract (in Japanese) (See Japanese page) 
(in English) Appropriate occlusion-processing is absolutely necessary for reconstruction of fine 3D images in computer holography. A method called the switch-back technique allows us to drastically reduce computation time of the occlusion-processing based on the polygon-by-polygon silhouette light-shielding. In this technique, further reduction of computation time can be achieved by splitting an object to some sub-objects along with depth direction. However, the number of numerical propagations between the sub-objects increases with increasing the number of sub-objects. As a result, there is an optimum number of sub-objects. In this paper, we propose a novel technique to estimate more accurate optimal number of sub-objects than that by the conventional technique.
