Abstract: An apparatus for synthesizing ultra-high resolution computer generated holograms based on mesh propagates a plurality of 3D meshes constituting the 3D model to a hologram plane, divides an entire angular spectrum area corresponding to a set maximum diffraction angle into a plurality of partial angular spectral areas, sequentially calculates and accumulates angular spectrums of the plurality of 3D meshes for each of the plurality of partial angular spectrum areas, and generates holograms for the 3D model from the angular spectrums accumulated for each of the plurality of partial angular spectrum areas.
