Kinetic depth effect
Encyclopedia
In visual perception
, the kinetic depth effect refers to the phenomenon whereby the three-dimensional structural form of an object can be perceived when the object is moving. In the absence of other visual depth cues
, this might be the only perception mechanism available to infer the object's shape. Some cues could lead to identify the correct shape, dynamic changes in texture density is one cue.
For example, if a shadow is cast onto a screen by a rotating wire shape, a viewer can readily perceive the shape of the structure behind the screen from the motion and deformation of the shadow.
In order to model the calculation of depth values from relative movement, many efforts have been made to infer these values using other information like geometry and measurements of objects and their positions .
This is related to the extraction of structure from motion
in computer vision
. It is used in parallax scrolling

Depth perception
Depth perception is the visual ability to perceive the world in three dimensions and the distance of an object. Depth sensation is the ability to move accurately, or to respond consistently, based on the distances of objects in an environment....

Computer vision
Computer vision is a field that includes methods for acquiring, processing, analysing, and understanding images and, in general, high-dimensional data from the real world in order to produce numerical or symbolic information, e.g., in the forms of decisions...

Parallax scrolling
Parallax scrolling is a special scrolling technique in computer graphics, popularized in the 1982 arcade game Moon Patrol. In this pseudo-3D technique, background images move by the camera slower than foreground images, creating an illusion of depth in a 2D video game and adding to the immersion...
