parallax

Parallax occurs when closer objects appear to shift more than objects that are further away as your point of view shifts. Try shifting your head from side to side (position, not rotation) and notice how objects around you appear to move at different speed. This very noticeable difference in motion between objects near and far is parallax. In VR, when objects don’t have parallax, we interpret the scene as flat even if captured in stereo. Parallax is a key visual cue which allows the brain to understand the world around us, and is one of the obvious advantages that Light Field video provides over 360° video.
