April 2013

Volume 66, Issue 4

cover: Because our two eyes are physically separated by a few centimeters, each observes a slightly different perspective of a scene. Thanks to that disparity, a pair of two-dimensional stereoscopic images, such as those on the cover, can provide the illusion of depth. The technologies for creating that illusion and for generating 3D reproductions of a scene have matured since Charles Wheatstone proposed the concept of the stereoscope in the 1830s. For a survey, turn to Byoungho Lee’s article on page 36.
