single angle of view.Real 3D objects also provide the important visual cues of parallax and motion parallax.Parallax is the different view each eye receives because of their physical separation.Motion parallax is the change in the image due to the motion of the viewer.Recent advances in stereo-pair displays, notably by Tektronix and Stereoflraphics, have made them viable for many applica-L E HUMAN VISUAL SYSTEM perceives and interprets a truly three-dimensional world-one in which objects having volume exist and interrelate within a volumetric space.Current simulated and stereo-pair 3D displays simulate the volumetric space with varying degrees of success, but are clearly inadequate for many applications.What is needed is a real-time display that creates a true 3D image which occupies a volume and can be viewed from all sides by any number of people.Such displays, called multiplanar displays, currently exist in prototype form.
