The thing about 3D displays is that they need something to project the image ONTO. Sure, we have 3D cinemas and televisions and all that, but in all of those we are dealing with a 3D image being shown on a 2D surface.

To project a 3D image into thin air is beyond any technology we have today.
I actually saw a 3d Display about 6 years back at SIGGRAPH that wasn't projected, which was generated by shining crisscrossing lasers so that where they intersected, the air was turned into a plasma and glowed.

Granted, it was 1 color, about 1dpi, and has a refresh rate of maybe 10hz, but it was really cool.

Re: 3D Display

if you have the projector at the front
You can always have a projector inside a mist cylinder. Or outside it, but surrounding it from several directions.

You can also give the mist specific shapes that get augmented by the light show: you can pulse the flow, you can have the sprinklers arranged in specific patterns, and so forth.

In any case, I don't think Daniels' gizmo shot a cloud of mist into the room first.
Probably not. But the principle could be the same: some futuristic <tech> like forcefields suspends a reflector in a point of space from which a beam of light can be bounced. Although with tech like that, one could no doubt also suspend an emitter of light at the selected point of space, without the need for separate projectors and canvases.

As for eye projection technology, it's just something today's technology can do - not something it really would be doing today. Helmet displays provide direct retina projection in many experimental military and medical applications, and it's a trivially short hop from there to using multiple beams and having them track the eyes of multiple users (there's commercial tech on the latter undergoing evaluation, say, for tracking the eyes of a car driver and sounding an alarm if they show signs of falling-asleep-style drifting).

To get 3D out of that, you just need to project different moving images to the left and right eye, which is the ages-old trick the 1960s 3D movies already mastered.

But still, any time you have the image being projected through any part of the mist, you're going to see it, like the old "laser beam through fog" trick.

But then that wouldn't fall into the category of "not far from been [sic] available today" that the OP spoke of.

True, I won't argue with you there, but I think we're a long way from taking this technology that looks at a single person's eyes from a short distance and using it to look at the eyes of a large group of people from a far distance.

Re: 3D Display

There's obvious commercial demand for it, tho - just watch "Minority Report".

Image interpretation algorithms today are already incredibly good at finding eyes in the crowd. Any pocket camera can perform miracles in that respect, and never mind professional face recognition applications. Keeping lasers pointed at the identified targets shouldn't be a problem at all, either, considering the obvious military parallels.

Re: 3D Display

While not even remotely cannon, this Esurance commercial uses those stupid *lamps* above the Ops and Con station on the bridge of the Abramsverse Enterprise bridge as 3D displays - which makes FAR MORE sense than having bringe *lights* shining down on LCD screens!!! (What is that for even? To make them easier to read? Uh...ever tried to read a LCD flat screen in bright light? They light doesn't help, as EVERYBODY IN THE WORLD knows!)

Every since I first saw them, I had hoped that they would turn out to be 3D HUD (Heads-Up Displays) projectors...or at maybe the Abramsverse version of those goose-neck displays on the bridge in "The Cage" and "Where No man Has Gone Before" (and in my mind, that's what they are.)

Anything but Gods-damned redundant *lamps*!!!

Anyway, here is the commercial...

Re: 3D Display

The lamps-as-projectors thing is a fun (if unintended) tie-in to the gooseneck displays of early TOS. You know, these?

http://tos.trekcore.com/hd/albums/1x...cagehd0043.jpg

Of course, those were an homage of sorts to the speaking tubes of more primitive ships, and the new positioning in "Where No Man" reinforces that image; the ST:ID-based commercial just takes the homage one step further. Essentially, we're seeing some sort of a primitive technology that is on its way out in TOS already (only Kirk retains his "tube" in the second pilot) but hasn't disappeared yet in the alternate timeline.

Re: 3D Display

The line from "The Visitor" is

I haven't worked a two-dimensional control panel in a long time...
I have a question. Which would be easier on the eyes - working on a three dimensional display in a fully lit, white room or in a less lit, darker room? I would think the latter.
