When any observer receives an image of a scene having the same relative size, shape and location on the retina of each of his two eyes at any instant and the image of the scene has some component of horizontal motion in any direction, the image viewed is three dimensional. If the motion occurs, all scene-object points are spatially located in playback since all of the original ray angles between camera and scene points are reproduced for both eyes by the ray cross-overs at the scene image points. When successive frames are presented, the brain cognizes the motion in linking the frames by persistence of vision. For the brain to perceive an item as moving it must connect these frames, but because of intersecting rays coming from any spatial location in successive frames, the brain cannot connect the frames without also locating the points in space.
