Submission + - Real 3D TV may be possible (computer.org)
adaviel writes: 3D movies and TV are getting a boost from all the hype over Avatar. But that's not real 3D, it's a stereo effect. If you move to the side, you'll see the same picture, not the scene from a different angle. For genuine 3D, you need holography — essentially, a diffraction pattern recreates the same light rays from a flat film as came from the original solid object. Back in the 1960's IBM made some computer-generated still holograms. Earlier this year, Mark Sich at Shell built a 100Mpixel colour display, and estimates he'd need a 19Tflop computer to run a 2m realtime holographic display. Given Moore's Law and some creative engineering, that may well be within reach in only a few years. We can have the telepresence hookup from Star Wars, without the fuzzy picture and wobbly display, or 3D CAT scan displays for surgeons.
