Volumetric displays & implementation experience

Abstract

• Programmable control over the position from which light is emitted. • Light is actually emitted and perceived at a single point. • There is no conflict of physiological depth cues. • Display designs usually involve transparent voxels that emit isotropically. Volumetric displays are characterized by the ability to program light at discrete positions within a volume. In contrast to multiview displays, volumetric displays emit light from the same 3-D points that are perceived by the viewer. Therefore, consistent physiological depth cues are produced, no matter the viewer location or the bandwidth of the display. Many volumetric display designs lack the ability to accurately portray occlusion and shading, however there are some designs that may provide these view-dependent depth cues. A volumetric display image consists of a dense 3-D array of addressable locations whose optical properties can be controlled. These locations are called voxels.
