An Algorithm for Object-Light Calculation Considering Reflectance Distribution for Computer-Generated Holograms

Abstract

To achieve realistic 3D displays using by computer-generated holograms, both modeling and rendering methods are key techniques. In this paper, we propose a new algorithm for object-light calculation considering reflectance distribution, which is based on fast processing of spatial frequency. The method is applied to Phong's reflection model, which is a well-known model in computer graphics. The results of optical experiments show that the method can be successfully applied to computer-generated holograms.
