Psycho Visual Modeling: The Beans Don’t Move, Your Brain Moves Them

Our brain is designed for living outdoors in a 3D world.  Seeing things in two dimensions and extracting depth is actually a trick we learned over time.  As revolutionary as perspective was in painting, the ability to give the brain cues to interpret more depth from an image has never really been applied to video or film.  It was always assumed that to make good 3D you needed to have two camera’s, or sophisticated motion interpretation so that a computer could calculate the depth from parallax.  In much the same was as the beans below appear to move even though they are not, given the right visual cues your brain can make any 2D Image 3D, and because your brain is doing the work it very rarely will get it wrong.
