Kinetic Depth Effect

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.
