Abstract

This paper presents a computer graphics algorithm useful for rapidly generating image data for full parallax spatial displays such as full parallax holographic stereograms. Other techniques such as custom-designed ray-tracing packages and image-based rendering techniques have significant disadvantages for rapid display production. In contrast, the method described here uses scanline-based computer graphics techniques. The described implementation uses the widely available OpenGL^TM graphics library and takes advantage of acceleration by computer graphics hardware subsystems. The time required to render the image data of a moderately-sized scene for a single holographic exposure is less than one second using desktop computer systems. This method is compatible with both one-step and master-transfer holographic recording geometries. Details of the algorithm are included.
