Studying why we see in 3D is essential to understand the basics of stereoscopic filmmaking and why some 3D images look better than others. The brain mechanisms of vision remained mysterious for a long time, and even today the very foundations of stereoscopic vision are still partially unknown.
Basics of 3D Vision
Many animals have two eyes just like us, including most mammals whose field of vision has a central area where the separate fields of both eyes overlap. It is within this overlapping area that we are able to see in 3D. This is called binocular vision.
Having binocular vision has many benefits: Experiments show that our ability to detect and recognize shapes and objects is better when seen by both ...
