Abstract (in Japanese) (See Japanese page) 
(in English) A novel method for hidden surface removal is proposed in full parallax CGHs. This method is an improvement of the conventional silhouette method and calculates the object field faster than the conventional method in cases of creation of large-scale CGHs. The conventional method requires the same number of operations of total field propagation with the number of objects, whereas this method shields light based on the Babinet's principle and partial field propagation and does not use total field propagation at all. Therefore, in creation of large-scale CGHs that needs segmented frame buffers, the proposed method calculates the object field of occluded scenes much faster than the conventional method.
