Real 3D Display; 3 Years Out?
Bob the Super Hamste writes "Fortune magazine is reporting that the company Zebra Imaging is producing a 3D hologram table that will project a 360 degree 3D image that doesn't require glasses. Funding for this project is being provided by DARPA for battle planning. The company expects it will take at least another three years for the table to be ready for commercial applications."
What the heck is a "hogel"?
Voxel is the correct term for the volume represented by a 3D pixel...
No, you can't. You could theoretically use a Kinect to figure out where the image should be projected, however you're not really solving the problem of having an image that can't be viewed from multiple angles and it would only work if the viewers were sitting next to each other at which point you might as well just manually adjust it yourself..
No current federal politician will ever lower funding for defense. Their opponents will quickly use it to crucify them.

It's better to vote for what you want and not get it than to vote for what you don't want and get it.

This seems much closer instead of the fake 3D as I always hear people complain that it isn't 3d unless they can walk around it. Besides if you wanted a holodeck just have one of these as your floor but don't try to sit on the projected chair.

How about have this in your living room floor so that you are really immersed in the environment.

Holograms have been used in shows for a while, the problem with them is tha they are too computationally intensive for realtime use. The article only talks about still images, so I guess this is not a 3D television, more like a virtual diorama.
From what I understood, they're planning to use phase shifters working in the optical range. How the hell they're going to do that is absolutely a mystery for me.
Creating 'holograms' in radio frequencies is easy, that's what phased arrays do. They're trying to adapt this for much shorter wavelengths - and this gets very hard.
Voxel is a pixel in a mapped 3D space, for a holographic display simply displaying voxel information you would run into the problem of being able to see things that are behind other things. Hogels have extra information that tells how light passes (or does not pass) through them at different angles - solving the problem of looking at a "solid" projection yet seeing what should be covered behind it.
The industry? People want 3d. They've always wanted 3D. There's no 'shoving' about it. Haven't you wondered why 3D has been a reoccuring gimmick and that each time it resurfaces with better technology it makes MORE money?

If people wanted 3D then plays would be a lot more popular.
Don't know something? Look it up. Still don't know? Then ask.
But you could, if this technology is scaled up enough. A small 12"x12" display is limited in scope, but scale it up to an 84"x84" display, and then mount six of them orthogonally facing a single point, combined with a transparent motion-tracked conveyor system, and you've got yourself a pretty damned immersive 3D environment in which you can run around in.
Of course, a highly accurate motion tracking system that can determine how you should be moving relative to the ground while keeping you motionless is a pretty tall order itself. Essentially, the conveyor must accurately simulate inertia for a specific human body to make walking feel natural.
