Parallax is the apparent displacement of an object because of a change in the observer's point of view.
Parallax also affects optical instruments such as rifle scopes, binoculars, microscopes, and twin-lens reflex
cameras that view objects from slightly different angles.
Many animals, along with humans, have two eyes with overlapping visual fields that use parallax
to gain depth perception; this process is known as stereopsis.
In computer vision the effect is used for computer stereo vision, and there is a
device called a parallax rangefinder that uses it to find range, and in some variations also
altitude to a target.
