Recent research presented during the recently concluded SIGRAPH conference focused on the design and implementation of affordable 3D or holographic displays as are more commonly known. A team from the University of the Southern California, Fakespace Labs and SONY presented a paper on their autostereoscopic, omnidirectional and multiview 3D display. Autostereoscopic basically means that you do not need any type of special apparatus such as glasses in order to see the rendered images in 3D. Omnidirectional means that the models rendered look good from all directions. Finally, multiview entails that multiple people can be watching the display and seeing a correct rendering of the image from their point of view.
The title of the paper is “Rendering for an Interactive 360ยบ Light Field Display“; the abstract explains the focus and contributions of the work,
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. 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.
I am not an expert in 3-dimensional display technology but this work is exceptional. You can download the paper and/or view a movie of the display here.

Great article and this technology is moving very fast along with the Spectral Imaging field. We will see the Star Wars Cell Phones with Holographic Imaging within a few years. Our Online Think Tank wrote a book on Holographic Technologies, which you can look up on the Internet.
