Not quite at the “help me, Obi Wan Kenobi” stage, but we’re getting there…

UPDATE: Well, maybe not so much. See comments…

    The bottom two (Voxon) are serial projection onto a high speed surface (aka “Swept volume display”) to simulate 3d, the top one (Holovect) is a 2d image of a rotating 3d shape projected through a 2d sheet of water droplets and is thus no more a 3d image than the youtube video of it on your monitor.

    (Holovect is therefore often dismissed as a “scam” because the creators really, really unplay the limitations in their kickstarter videos. And… well… it is a scam. But if you could quickly move the droplet layer, the way the projection-membrane is rotated in the Voxon version, you could have a true 3d mid-air hologram that you could pass your hand through. (Which you can’t with the moving screen, note how carefully the Voxon demonstrators keep their hands out of contact, the real thing works inside a glass dome.))

      OK. This was the first I’ve seen of Holovect, at least that I can recall. So the question is: if the system was used to project, say, a cube and leave it static… non-moving, non-rotating, and the viewer were to change position, it would soon become obvious that the “cube” was a 2-d image? So it only looks like 3-d from one angle?
