Q

Monocular Cues

A

(visual cues don’t need two eyes to receive)
1) relative size -> object closer is bigger
2) relative height -> object taller is further
3) interposition -> overlapping
4) linear perspective
5) texture gradient -> less detail further away
6) size/shape/color constancy -> all change close vs. far
7) shading contour
8) motion parallax -> object further appears to be moving slower
