We rigorously present the geometric issues related to binocular imaging. We identify the minimum number and most fundamental conceptual set of parameters needed to define 3D-stereoscopic camera and display systems; the fundamental parameter that is needed to specify a 3D-stereoscopic system but not a monocular system is the pupillary distance. We analyze the constraints that are imposed on the values of the parameters by the requirement that the imagery be geometrically indistinguishable from the reality that would be perceived by the `naked' human visual apparatus. We relate our approach to those employed by several well known textbooks and graphics engines.
