A stereogram is an image which, when viewed with two eyes, produces the illusion of depth perception. They were made popular by the Magic Eye book series in the 1990s. These versions were made on computers, and use subtle changes in a repeating pattern to combine depth information for both eyes into one single image.

What is stereoscopic viewing?

Stereoscopy, or solid vision, is the term given to the following natural phenomenon: When a person looks simultaneously at two photographs that have been taken of the same scene from two viewpoints, viewing one photograph with each eye, he can see an image of the scene in three dimensions.

What is stereoscopic effect?

Stereoscopy, sometimes called stereoscopic imaging, is a technique used to enable a three-dimensional effect, adding an illusion of depth to a flat image. Stereopsis, commonly (if imprecisely) known as depth perception, is the visual perception of differential distances among objects in one’s line of sight.

How is stereoscopic vision useful to humans?

In humans, for the last 150 years, stereo vision has been turned to a new use: helping us reproduce visual reality for artistic purposes. By recreating the different views of a scene seen by the two eyes, stereo achieves unprecedented levels of realism. However, it also has some unexpected effects on viewer experience.
