psych monacular/binocular cues

monacular cues

require 1 eye

binocular cues

require 2 eyes

binocular disparity

The brain takes into account that eyeballs are in two slightly different spaces. The closer something is, the greater the disparity.

binocular convergence

The closer something gets to you, the more your eyes turn in.

relative size

The farther away something is, the smaller of an image that is produced on the retina.

linear perspective

Parallel lines converging we see as farther away

occlusion

when one object occludes another, the occluder is closer

texture gradient

more details mean something is closer, farther away seems to smooth out

motion parallax

things closer than our fixation point feel like they’re moving away and faster, but things farther than our fixation point seem to be moving with us and slower

height in image

things that are closer appear bigger, things that are higher up appear farther away
