Abstract
AbstractIn this paper we report a method of removing hidden surfaces in full‐parallax computer‐generated holograms. First, we examine the handling of light shielding by tilted patches in terms of wave optics, and then propose a silhouette approximation. In addition, we derive a recurrence formula to synthesize object light waves with hidden surface removal by the proposed method. We show that appearance of optically reconstructed surface object of the full‐parallax holograms generated by the proposed method varies in a natural manner as the observation point is changed. This study achieves hidden surface removal in full‐parallax holograms, which was believed to be possible only if vertical parallax is ignored. © 2007 Wiley Periodicals, Inc.
