Real-time rendering of computer-generated hologram with the view volume transformation based layered method

摘要

A layered rendering method for generating computer-generated hologram (CGH) of 3D objects based on view volume transformation is presented. The shape distortion and the size deviation of the 3D reconstructed image existing in conventional layer-based methods are avoided, and the reconstructed 3D image can preserve the real size of the original model with high quality. Real-lime interaction with the digitally reconstructed holographic image with clear depth cues is experimentally demonstrated.
