And NOW.... This is pretty impressive:

I'm sick of the bulls**t glasses-3D recycled tech from a century ago.



This is real "3D Holographics".



Basically you have a very high-density LED 3D-Array within a very small space.



The experiments so far above are like when computers only had a green screen and 80 lines of text.



The next challenge is to have a VGA-resolution 3D Array, ie. an LED cube 640 x 480 x 480 pixels,

in a density of about 5" or so each dimension.



Next keep bumping it up.



With a 1280x1280x1280 voxel LED array in about 10"^3 of space,

you would be able to get something about as complex or more complex than like this from the Matrix:







The only thing is the above Matrix device is projected light not an actual embedded array of LED lights.



Of course, this 3D-LED array is the first step before they can achieve laser or whatever projected 3D images in empty space.

But we got to start somewhere and by 2025 3D LED displays will be quite common.



In 15 years we could have "4K resolution" digital projection of true-3D LED array screens. Easily.

It will make our current 2D "3D" look like VHS.



I feel the revolution is upon us.



They have already massively miniaturised LED/LCD screens to very dense resolutions, eg. 2560x1440 pixels in 20"-30"

Just add a depth dimension, ie. bringing it to 2500x2500x2500 voxels. It could be in various shapes, probably a globe

would be useful for multi-touch. Boom!

    Unfortunately, glasses are still the most reliable method of getting 2D projections to look like 3D because they are viewer-independent. The 3D array of lights won't be commercially viable due to the space it uses and picture quality.



    Light has to reflect off something to be visible so the effects you see in films can't exist until we find an invisible gas that transmits light at a high rate. Given that it would be invisible to light, we know it's not going to reflect it so the controlling source has to force each gaseous particle to somehow emit light.



    That's pretty much impossible to control. The 3D grid has the control but because the projecting elements are opaque, the light coming from nearby elements gets diffused and the more dense the mesh, the more opaque it gets.



    I think the best quality we will get is either a rotating flat panel or curved display coupled with the 2D depth technology we have. This way it remains cost-effective, have high quality, supports multi-touch and gives pretty much the same experience as a full 3D display.
