We have developed a novel 3D display that presents focus cues that are correct or nearly correct for the depicted scene. Additionally, the uncoupling of vergence and accommodation required by 3D displays frequently reduces one's ability to fuse the binocular stimulus and causes discomfort and fatigue for the viewer. Thus, focus cues-accommodation and blur in the retinal image-specify the depth of the display rather than the depths in the depicted scene. A likely cause of such distortions is the fact that computer displays present images on one surface. Unfortunately, 3D displays often yield distortions in perceived 3D structure compared with the percepts of the real scenes the displays depict.

In many of these applications, it is important for the graphic image to create a faithful impression of the 3D structure of the portrayed object or scene. Three-dimensional (3D) displays have become important for many applications including vision research, operation of remote devices, medical imaging, surgical training, scientific visualization, virtual prototyping, and more.
