What is stereopsis?
Roughly, you can think of stereopsis as depth perception. When a visually normal human being looks at an object, each eye sees it from a slightly different angle, and sends those "pictures" back to the brain. The differences between the two images are integrated into a single one, and the differences are used to show what is nearer, etc., creating the "3 D" effect.
