Sterio is a programming tool to allow 3D graphics engineers to use standard photographic units to take, import, and adequately convert the stereoscopic images into 3D model maps, apply appropriate textures, and subsequently enter them into the Unity 3D game engine.Sterio works with a stereo - photogrammetric system using a pair of photographs taken by the standard cameras directed on the same point. This means that Sterio doesn't require a user to purchase the special equipment or software used for 3D laser scanning.
