Three-dimensional stereoscopic display using ray traced computer generated holograms

Abstract This paper presents a method of displaying a computer graphics rendered scence in three dimensions using the methods of computer generated holography. The display hologram is of the autostereoscopic type, comprising a series of perspective views of the scene concerned. The approach developed in this paper uses a ray tracing graphic rendering method to produce realistic shaded scenes. The scenes are encoded holographically and written at a directly usable size on a high resolution optical plotter.
