      I'd say all the images look faked too. Could be that it's considered okay in France to fake your promo pics. I know it is here in the States.

      According to what little the "article" said, there is no screen, objects just float in midair up to eight inches away from the projector. But more to the point, how do you fool human stereoscopic vision into perceiving depth? Visual cuing works to an extent (even with only one eye) but only in cases where the brain is already familiar with the classes of objects involved and can make reasonable judgements as to relative size and distance. Otherwise you would have to provide slightly different images to each eye (like the LCD glasses another poster mentioned.) I dunno, sounds like more hype than substance here. Maybe they're generating changing interference patterns that somehow interact in midair to product a floating image ... nah. I think it's a crock much as I'd like to believe otherwise. I still remember an episode of ST:TNG when Captain Picard was sitting in his ready room examining a hologram of some unusual stellar system, and it was floating above, and appeared to be generated from, the Captain's desk. I thought that was slick. I know I wanted one.

      What you do is mount a screen on a spinning doohickey. As the screen rotates, different images flash on the screen. Make the pixels flash at the right time, and the speck of light will appear to float in space. Use enough dots, and you can make an image.

    The problem is getting the brain to provide the 3D image.

    3D displays using 2D devices rely on getting each eye to see something just a little different. With the old 3D glasses, for instance, one eye sees no blue, the other no red, with each image being slightly different, and the brain gets the blue from one and the red from the other. The brain converts that into a result it can handle. Don't ask me how.

    With a rotating screen, each eye would see a slightly different image. Depending on how fast the thing rotates, the brain could interpolate the results into 3D.

    Just a guess, but it's a brilliant concept if it works.

    This isn't exactly new. It sounds like this system I saw a while back. I'm sure I'm oversimplifying it, but it basically has something akin to a thin pane of glass that spins around really fast.

    What they do then is project a different image at each angle onto the glass. The images themselves are kinda like slices of a 3d volume (think volumetric textures). It spins just fast enough to fool the human eye into thinking it's seeing something hovering in midair.

    I saw a few QuickTime VR demos of one of these a while back... they showed it with some wireframe terrain and a little purple jet thing in midair, as well as showing the sugar molecule.

    Also, if I remember rightly, Nintendo had one of these puppies up a few E3s ago, with a model of that Star Fox character in it. Quite cool.

    As for manipulating it by hand, I sure hope I'm wrong about the spinning glass bit...

  24. A spinning spiral in an evacuated chamber? by fyngyrz · · Score: 2, Interesting
    A spinning spiral (think Archimedes screw) places a targetable surface at every XYZ location in the entire volume it occupies during the time it takes to make one rotation.

    So by modulating when you illuminate it (and what color, and how bright) you should be able to create a very nice representation of multiple objects; since the illumination only plays at the appropriate location in space, no glasses or other viewer-end tricks would need to be employed. It wouldn't look 3d, it would be 3d.

    There would be size/material limitations, of course - the larger this thing is, the faster the outer edges have to go to get the same update speed. This would be a better approach for a personal viewing device than a group viewing device, I think.

    Or, if you used a white surface, so that exact front-view objects could be created, put these spinners into "glasses" that would physically travel with the user, then sensing the viewers position would allow the display to change appropriately.

    You could do some interesting things with a non-glasses version by making the screw something that varies in transparency as well - LCD or electrically controlled polarization. It'd have to be fast, though. LCD might not like the kinetic energy applied by the spinning, either.

    It seems to me that all of the really hard complexity is in the illumination end, not the display end. Where do we get 3D information about the world? It's fine if you have synthetic scenes, for instance the output of a ray tracer, but to record 3D information about a real scene... ouch.
