Abstract

A novel technique is presented for calculating large-scale CGHs by using polygon-based method. In the technique, wave fields are regionally segmented and propagated by using the shifted Fresnel method. As a result, large CGHs can be calculated even in the case that the whole frame buffer can not be stored in main memory. The produced full-parallax CGH has the size of four billion pixels and reconstructs the fine image of a smooth surface object accompanied with a strong depth sensation.
