Multiscopy
Encyclopedia
In contrast with 3D binocular stereoscopy
(displaying a 3D scene via a left-eye and right-eye angle), 3D multiscopy displays multiple angles at once. This allows a viewer to move their head around the 3D subject to see it from different angles.
Stereoscopy
Stereoscopy refers to a technique for creating or enhancing the illusion of depth in an image by presenting two offset images separately to the left and right eye of the viewer. Both of these 2-D offset images are then combined in the brain to give the perception of 3-D depth...

Examples
Examples of multiscopic (as opposed to stereoscopic) 3D technologies include:- ParallaxParallaxParallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines. The term is derived from the Greek παράλλαξις , meaning "alteration"...
-based technologies - parallax barriersParallax barriersA parallax barrier is a device placed in front of an image source, such as a liquid crystal display, to allow it to show a stereoscopic image or multiscopic image without the need for the viewer to wear 3D glasses...
(e.g. Nintendo 3DSNintendo 3DSThe is a portable game console produced by Nintendo. The autostereoscopic device is able to project stereoscopic 3D effects without the use of 3D glasses or any additional accessories. The Nintendo 3DS features backward compatibility with Nintendo DS series software, including Nintendo DSi software...
) - integral imagingIntegral imagingIntegral imaging is an autostereoscopic or multiscopic 3D display, meaning that it displays a 3D image without the use of special glasses on the part of the viewer. It achieves this by placing an array of microlenses in front of the image, where each lens looks different depending on viewing angle...
(lenticular sheets or fish-eye arrays) - Volumetric technologies:
- sweeping a projection across subsurfaces
- transparent substrates (such as "intersecting laser beams, fog layers")
- HolographyHolographyHolography is a technique that allows the light scattered from an object to be recorded and later reconstructed so that when an imaging system is placed in the reconstructed beam, an image of the object will be seen even when the object is no longer present...
