Some important techniques, such as parallel/segmented computing, specular rendering, hidden surface removal, are developed for creating large-scaled computer-generated holograms by polygon-based methods. A hologram composed of 25 billion pixels, whose size is approximately 13.11cm^2 and viewing angle is more than 45°, is created in the top data. This hologram reconstructs true fine 3D images with a strong sensation of depth, which has never been achieved by conventional 3D systems, and therefore has been selected as a special exhibition taking place in MIT museum(Cambridge, USA).
