Abstract
This paper presents a new method for calculating Computer Generated Hologram (CGH) for 3-dimentional (3D) display. A "Ray-Sampling (RS) plane" is defined near by the object, and the wavefront at the RS plane is calculated from the light rays that can be obtained from multi-view images. Then the Fresnel diffraction from the RS plane to the CGH plane is calculated. Since the CGH is calculated from the light-ray information, the image data generated by artificial computer graphics or captured by camera array can be used. It is possible to reproduce the angular reflection properties which is important for highly realistic 3D image. In the experiment, high-resolution 3D image with gloss appearance is simulated with using multi-view images data generated by commercial rendering software.
