Depth Perception

Part 2 of 7 — Depth Perception

1. Binocular cues

retinal disparity, convergence (need both eyes)

2. Monocular cues

relative size, overlap, linear perspective, texture gradient

3. Motion parallax

closer objects appear to move faster

4. Depth perception develops around 6 months (visual cliff)
