Depth sensation is the corresponding term for non-human animals, since although it is known that they can sense the distance of an object, it is not known whether they perceive it in the same way that humans do. [1] Depth perception arises from a variety of depth cues. These are typically classified into binocular cues and monocular cues ...
In film, photography and art, perceived object distance is manipulated by altering fundamental monocular cues used to discern the depth of an object in the scene such as aerial perspective, blurring, relative size and lighting. [12] Using these monocular cues in concert with angular size, the eyes can perceive the distance of an object. Artists ...
Stereoscopy creates the impression of three-dimensional depth from a pair of two-dimensional images. [5] Human vision, including the perception of depth, is a complex process, which only begins with the acquisition of visual information taken in through the eyes; much processing ensues within the brain, as it strives to make sense of the raw information.
In the Müller-Lyer illusion, the visual system would in this explanation detect the depth cues, which are usually associated with 3D scenes, and incorrectly decide it is a 3D drawing. Then the size constancy mechanism would make us see an erroneous length of the object which, for a true perspective drawing, would be farther away.
Visual art could now depict a single, unified scene, rather than a combination of several. Early examples include Masolino's St. Peter Healing a Cripple and the Raising of Tabitha (c. 1423), Donatello's The Feast of Herod (c. 1427), as well as Ghiberti's Jacob and Esau and other panels from the east doors of the Florence Baptistery.

It also involves groups of objects appearing denser as they move further away. Additionally, it could be explained by noticing a certain amount of detail depending on how close something is, giving a sense of depth perception. There are three main forms of texture gradient: density, perspective, and distortion of texture elements.
Art and Illusion, A Study in the Psychology of Pictorial Representation, is a 1960 book of art theory and history by Ernst Gombrich, derived from the 1956 A. W. Mellon Lectures in the Fine Arts.
The Necker Cube: a wire frame cube with no depth cues. Figures drawn in a way that avoids depth cues may become ambiguous. Classic examples of this phenomenon are the Necker cube, [6] and the rhombille tiling (viewed as an isometric drawing of cubes). To go further than just perceiving the object is to recognize the object.
