| - A volumetric display device is a graphical display device that forms a visual representation of an object in three physical dimensions, as opposed to the planar image of traditional screens that simulate depth through a number of different visual effects. One definition offered by pioneers in the field is that volumetric displays create 3D imagery via the emission, scattering, or relaying of illumination from well-defined regions in (x,y,z) space. Though there is no consensus among researchers in the field, it may be reasonable to admit holographic and highly multiview displays to the volumetric display family if they do a reasonable job of projecting a three-dimensional light field within a volume. Most, if not all, volumetric 3D displays are either autostereoscopic or automultiscopic; that is, they create 3D imagery visible to the unaided eye. Note that some display technologists reserve the term “autostereoscopic” for flat-panel spatially multiplexed parallax displays, such as lenticular-sheet displays. However, nearly all 3D displays other than those requiring headwear, e.g. stereo goggles and stereo head-mounted displays, are autostereoscopic. Therefore, a very broad group of display architectures are properly deemed autostereoscopic. Volumetric 3D displays embody just one family of 3D displays in general. Other types of 3D displays are: stereograms / stereoscopes, view-sequential displays, electro-holographic displays, parallax "two view" displays and parallax panoramagrams (which are typically spatially multiplexed systems such as lenticular-sheet displays and parallax barrier displays), re-imaging systems, and others. Although first postulated in 1912, and a staple of science fiction, volumetric displays are still under development, and have yet to reach the general population. With a variety of systems proposed and in use in small quantities — mostly in academia and various research labs — volumetric displays remain accessible only to academics, corporations, and the military.

Practical applications require very sophisticated hardware, which limits the use of such devices to large corporations, installations and certain ships (on which they are used to great effect in navigation). The most common use is of static volumetric display (or SVD), in which a beam of light is manipulated so that it's focal point will create a select point of plasma (also known as a voxel, or 3D pixels) that glows. Progressive sophistication have allowed the voxels to become smaller and more precise, allowing for greater definition of the projected shapes and images.
