The real world that our eyes see is not just a simple plane image, but a three-dimensional 3D with depth of field. This ability to perceive 3D is a result of the inconsistency of the retina (or a slight shift in the position of an object seen by the left and right eyes). side function. Therefore, if a stereoscopic projection system is to be designed, it must simulate the parallax of human retinal imaging when viewing objects.
