The Physiology of 3D Perception
Summary
As one eye is capable only of perceiving a planar image, 3D viewing is commonly achieved by the cooperation of both eyes in providing each eye with a view of the object. The images that the eyes receive from the same object are different according to the different locations of the eyes. This binocular viewing provides the perception of depth, the third dimension, as further explained by the horopter circle. This chapter considers a phenomenon explicable with known stereoptic facts. In stereoscopic and autostereoscopic displays the two required views of an object are presented next to each other on the screen of a display. In stereopsis there are two definitions of perceived distance or depth. Immersive stereo displays such as 3D movies and 3D TV create real-world scenes by presenting a variety of cues to depth and distance.
