A real 3D Display - like as in holograms

Posted yesterday. Pretty cool though, don't you think? Ryan Being little and getting pushed around by big guys all my life I guess I compensate by pushing electrons and holes around.

Punctuality is only a virtue for those who aren't smart enough to think of good excuses for being late - John Nichol "Point Of Impact"It works by having an LCD display rotating at high speeds and using complex calculations to make the right pixels light up at just the right time in the rotation. Because of persistence-of-vision, it appears that there is a stationary 3D image. Notice the slight gray blur in the center though.

"An eye for an eye only makes the whole world blind." - Mahatma GandhiYep. I didn't actually look too much at it before. It actually projects an image onto a rotating disk. It's got some pretty impressive hardware - 384MB of DDR memory, 1600MIPS processing power. Unfortunately, at it's highest resolution it only has 8 colours :( I think it'd still be pretty cool, though. Just for the geek factor :) Ryan Being little and getting pushed around by big guys all my life I guess I compensate by pushing electrons and holes around.

Check this out (hopefully not a repost). Its a crystal ball like device that gives you a 360 degree view (thats you moving and not the device) of a volumetric image. http://www.actuality-systems.com/volumetric3d.php3[^] Andy

Cool system, but what ever happened to that hologram technology marketed last year? They had it at some trade show where they had coke cans and toasters floating in the middle of the booth, you could walk through them no orbs of glass or anything. Remember it?

"An eye for an eye only makes the whole world blind." - Mahatma GandhiIts actually a spinning sheet of plastic, onto which they project the image. Other than that, your description is dead on. The sheet spins and the optics project the image on to it. The processors ensure that the image being projected is transformed correctly for the angle at which the sheet currently at. blah blah blah. Does anyone remember that hologram arcade game. It was a golden axe type adventure but with FMV actors instead of sprites. Needless to say, it was totally unplayable, but the holograms really did just hover above the horizontal screen. No plastic sheets spinning around or anything. Pete

Actually I am pretty sure my memory on this hologram thing is real, not some drug induced fantasy (because if it were drug induced would I be fantasising over coke cans and toasters in 3D? Oh no, most definitley not... ;) )

Yeah, I remember seeing that in an arcade once... looked really cool, but the actual projection was really small and none of my friends really figured out how to play it :) It was called "Time Traveller" and was released by Sega. Here's some interesting info on it: http://www.geocities.com/wiredlounger/mpog/reviews/timetraveler/timetraveler.html[^] - Mike

Thats the badger! God it was rubbish. Shame no-one made the most of the display tech though... Pete

I remember that, too. It was on a TV news show or something. They showed some fun clips of people staring at a spinning Pepsi can, trying to figure out how it stayed up, then eventually realizing that the can wasn't really there. :D "Yeah, and I invented the spellchecker" - fellow inventor Dan Quayle on hearing that Al Gore invented the Internet.
