Kinetic Depth Effect
From Wikipedia, the free encyclopedia
In perception, the kinetic depth effect refers to the phenomenon whereby the three-dimensional structural form of an object viewed in projection can be perceived only when the object is rotating.
If a shadow is cast by a rotating wire shape onto a screen, a viewer can readily perceive the shape of the structure behind the screen from the dynamic shadow pattern.
This is related to the extraction of structure from motion in computer vision. It is used in parallax scrolling.
