Document Summary

How do we transform 2d retinal images into 3d perceptions: monocular cues a. i. Will provide information of how far something us, and will require only one eye. Relative size: you work with the information provided from the retina, it is a flat surface, it flashes and triggers it. Linear perspective - things smaller make us believe things us further away. Texture gradient - makes things fuzzy - something that overlaps something must be in front therefore closer. Motion parallax - your perception of depth as you are moving. Things closer to you will not be moving as fast: binocular cues b. i. Simply the difference in the image between imprint on the left eye vs the imprint on the right eye, That difference is used by your brain to calculate how far something might be. It can determine from the difference of the images how far something might be. Give your brain a good illustration of how far something is.
