Can the Holodeck Be Too Far Off?
A technology dubbed “autostereoscopic light field display” makes the claim it is able to present interactive 3D graphics to multiple simultaneous viewers 360 degrees around the display.
The USC developers of the device — Andrew Jones, Ian McDowall, Hideshi Yamada, Mark Bolas and Paul Debevec — describe it this way in 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.
The display was highlighted at the opening of the new USC Stevens Institute for Innovation.
To view the image in 3D cross your eyes and try to merge the center image (of the three you will see) into one. You may have to tilt your head a bit to the right or left to get your eyes perfectly aligned with the image.
Once you have the image “locked in” you can loot at various part of the image easily .. the hard part is merging them.

Wow! Finally a story on a piece of technology that can’t kill someone but entertain and educate. Aside from the obvious entertainment factor this technology is going to be very helpful in the medical field. Also I agree that there have been some pretty amazing stories posted the last week here on SOS about new and emergeing technology.
