A modification of the subhologram-based approach to the calculation of a computer generated display hologram of a 3-D scene is presented. The hologram area is split into subholograms. For each of them, a perspective image with depth coordinate is rendered and converted to a point cloud. These points are processed in a novel way and the optical field in the subhologram is calculated. The processing guarantees that the points used for the optical field calculation are the same for all subholograms (i.e., coherent). The coherence provides sharp hologram reconstruction. The parameters of the processing are designed to match the human vision requirements.
