ince we live in a three-dimensional world, we continously interact with 3D objects both near and far away.The human body can extract enormous amounts of information about its environment from a single sensory input: sight.Because we obtain over 70% percent of our sensory input visually, we judge shape, size, distance, relative position, movement, speed, and a host of other physical attributes using the binocular vision provided by our two eyes.In addition, the human visual system works in real time, enabling us to interpret a 3D world that is changing rapidly.Our incredible ability to perceive depth through stereopsis, motion parallax, focus, and eye convergence is
