[1] This allows the observer to view the 3D subject from different angles as they move their head, simulating the real-world depth cue of motion parallax.
It also reduces or eliminates the complication of pseudoscopic viewing zones typical of "no glasses" 3D displays that use only two images, making it possible for several randomly located observers to all see the subject in correct 3D at the same time.
Photographic images of this type were named parallax panoramagrams by inventor Herbert E. Ives circa 1930, but that term is strongly associated with a continuous sampling of horizontal viewpoints, captured by a camera with a very wide lens or a lens that travels horizontally during the exposure.
The more recently coined term has increasingly been adopted as more accurately descriptive when referring to electronic systems that capture and display only a finite number of discrete views.
Examples of multiscopic (as opposed to stereoscopic) 3D technologies include:[2] This computer hardware article is a stub.
