Document Summary

Image on the retina - a flat projection of the 3-d world around you. The separation of objects in space is lost due to the 2-d image. The brain must reconstruct the information to form a. 3-d perception of the world based on a 2-d image on the retina. Cues to depth perception are clues to the relative ordering of objects in the world around us. The separation of objects is lost when we have the 2-d image on the retina (the objects appear attached). Relative ordering of points in terms of depth is lost in the image on the retina. Oculomotor cues: vergence/ convergence angle - eye muscles pulling inward (crossing eyes) changes the vergence/convergence angle. So one oculomotor cue is vergence which is pulling the eye muscles inward (crossing eyes). The closer an object is, the higher the convergence angle.
