Page "Volumetric display" Paragraph 9

For example, the 3D scene is computationally decomposed into a series of " slices ," which can be rectangular, disc-shaped, or helical cross-sectioned, whereupon they are projected onto or from a display surface undergoing motion.

The image on the 2D surface ( created by projection onto the surface, LEDs embedded in the surface, or other techniques ) changes as the surface moves or rotates.

Due to the persistence of vision humans perceive a continuous volume of light.

The display surface can be reflective, transmissive, or a combination of both.
