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 OpenGLTM 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.
