Definitions:

Linear Perspective

A system of creating an illusion of depth on a flat surface by converging parallel lines at a single point on the horizon.

Retinal Disparity

A binocular cue for perceiving depth based on the differences in the images seen by each eye because of their different perspectives, enabling three-dimensional perception.

Interposition

A visual cue used to perceive depth, where one object partially blocks the view of another, indicating that the blocking object is closer to the observer.

Interposition

A visual cue that allows us to perceive the depth by understanding that if one object partly blocks another, the blocking object is closer to the observer.
