Researchers at USC have taken another step towards that holiest of sci-fi dreams: the 3D holographic display. Using a spinning mirror covered with a "holographic diffuser," a special DVI implementation, and a high-speed projector, the team's device can project a three-dimensional image that can be viewed from 360 degrees -- regardless of the viewer's height and distance.
We describe a set of rendering techniques for an autostereoscopic light field display able to present interactive 3D graphics to multiple simultaneous viewers 360 degrees around the display. The display consists of a high-speed video projector, a spinning mirror covered by a holographic diffuser, and FPGA circuitry to decode specially rendered DVI video signals.
