STEREOSCOPY

[noun]

(also called stereoscopics or 3D imaging) a technique for creating or enhancing the illusion of depth in an image by means of stereopsis for binocular vision. The word stereoscopy derives from the Greek “στερεός” (stereos), “firm, solid” + “σκοπέω” (skopeō), “to look”, “to see”.

Most stereoscopic methods present two offset images separately to the left and right eye of the viewer. These two-dimensional images are then combined in the brain to give the perception of 3D depth. This technique is to distinguish from 3D displays that displaying an image in three full dimensions which gives the observer the possibility to increase information about the 3-dimensional objects being displayed by head and eyes movements.
