Paper Abstract

Computer generated holograms (CGH) are expected in holography 3D display for the reconstruction of realistic or artistic virtual 3D objects. We propose a CGH approach that combines computer graphics (CG) technology and wave propagation theory. Our approach is based on the following assumptions. Virtual 3D objects are described by the popular computer graphics format that uses a set of triangular surfaces, and CG technology can be used to render ray information on these surfaces. The hologram plane is flat. Each triangular surface is tilted (that is, not parallel) relative to the hologram plane. An advantage of our approach is that even though the surfaces are tilted, the sampling pitch on the tilted surfaces can be defined.
