This autostereoscopic display is able to display images in a 360 degree view - up to an amazing 5,000 frames per second. The display resolution is 768x768 in a displayed volume of a thirteen centimeter cube.
(Autostereoscopic 360 Degree Light Field Display)
The display was highlighted at the opening of the new USC Stevens Institute for Innovation. Here are portions of their abstract:
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. The display uses a standard programmable graphics card to render over 5,000 images per second of interactive 3D graphics, projecting 360-degree views with 1.25 degree separation up to 20 updates per second.
We describe the system's projection geometry and its calibration process, and we present a multiple-center-of-projection rendering technique for creating perspective-correct images from arbitrary viewpoints around the display. Our projection technique allows correct vertical perspective and parallax to be rendered for any height and distance when these parameters are known, and we demonstrate this effect with interactive raster graphics using a tracking system to measure the viewer's height and distance.
We further apply our projection technique to the display of photographed light fields with accurate horizontal and vertical parallax.
This cool display reminds me - in its appearance - to the description that Edmond Hamilton gives of his telestereo communication display in his 1928 novel Crashing Suns:
Abruptly I was aroused from my musings by the sharp ringing of a bell at my elbow. "The telestereo," I said to Hal Kur. "Take the controls." As he did so I stepped over to the telestereo's glass disk, inset in the room's floor, and touched a switch beside it. Instantly there appeared standing upon the disk, the image of a man in the blue and white robe of the Supreme Council...
