Speedup and scale-up of creation of polygon-based high-definition CGH by using parallel distributed processing

Abstract

Polygon-based methods accelerate computation of high-definition computer-generated holograms (CGH). However, the computation time is still very long in the cases where the object model has severe self-occlusion, because processing of hidden surface is necessary for computing the object field. In this report, a novel technique using distributed processing is proposed to speed up and scale-up the computation of high-definition CGHs of self-occluded objects employing the polygon-based method and the silhouette method.
