Soon, you too could talk to a hologram
Back when I was a wee nipper the future promised me many things. I look around now and see no hover-boards, sentient robots or tactile virtual worlds. However, conversing remotely with hologramatic people may not be far away it seems.
Queue this amazing example of art informing life. A “autostereoscopic light field display able to present interactive 3D graphics to multiple simultaneous viewers 360 degrees around the display”. In english… a magic projector.
Created by a collabration of people from the USC Institute for Creative Technologies, Fakespace Labs, Inc., Sony Corporation and the USC School of Cinematic Arts, this little gem has renewed my faith in the portents of the 80’s.
In their own words:
“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.”
Coming soon… A giant space station with the fire power of a thousand battle cruisers.
