Definitions:

Motion Parallax

A depth cue that involves images of objects at different distances moving across the retina at different rates when the observer is in motion.

Relative Size

A perceptual cue that allows the interpretation of the size of an object in comparison to another, contributing to depth perception.

Texture Gradient

A visual cue that refers to the gradual reduction of detail that occurs in surfaces as they recede from the observer, contributing to the perception of depth.

Convergence

The coming together of different factors or phenomena to form a unified whole, or the ability of the eyes to move inward together to focus on an object.
