Document Summary

Monocular depth cues: require only one eye, linear perspective. Aka vanishing point in art class: texture. Nearby objects are typically more clearly seen: clarity. Distant objects are less clear (almost hazy: interposition. Objects in front cut off parts of objects behind: height in horizontal plane. Near objects tend to be lower on the horizontal plane (farther from horizon: relative size. Farther objects take up less space on retina than equally-sized objects that are near to us: light and shadow. Gives us a sense of 3d shape, depth: motion parallax. As we move, nearby objects seem to zip past while far away ones seem to slowly move with us. Only one that is not a pictorial clue. Binocular depth cues: require both eyes, binocular disparity. Each eye sees a slightly different image of the world. Closer objects more of a difference. 3d movies, viewmaster slides use this to produce 3d images.
