"however tv's which dont require glasses been made "
FR, but I happened to pick you for the quote. I said it years ago that with multilayer LCD tecnology it was possible, most likely almost done. But on a screen like in a theater the only way to do it is with glasses. Movies were originally made possible by showing pictures in rapid succession, and I don't even remember, I think it was about fifty frames per second that made it happen. Well when there is no phosphor involved there is no persistence. What the advanced ones do is to show it at double the frame rate and the glasses just switch eyes. It can literally be called visual multiplexing.
However, with LCD technology it can be done without this muliplexing. That works on multiple layers and some extreme processing, and that is even if it is originally shot in 3D. And it requires a shitload of data, the bluray might handle it, but whether or not you know it bluray is already obsolete. Phillips and them guys got have a holographic disk and it's capacity is enormous. So much so in fact that it is not on the consumer market because nothing is out there that requires that much storage. That will change no doubt. And converting old material to 3D is probably a waste of time. It will be like the old orthophonic stereo records of the 1950s and 60s. Not worth the trouble and sounded better the original way. You can't recreate what is not there.
Now a true holograph is totally different. there is no screen needed at all. The interference of light rays produce an apparent image. Just the gunk in the atmosphere is enough, but can a holograph be projected in a vacuum ? I reall don't know. But I do know this, that if shot in 3D a movie requires at least double the information. That is for the most basic form of it. Watching real 3D on a screen would mean that you might move your head a but to gain a view of something. That means images much larger than the screeen. Now this is the kind of shit that can fill a bluray.
The new (three years ago actually) holographic disks have no defined layers like a dual layer DVD or anything. This is set during the burning process, and there will be no stamped disks like CDs or DVDs.
But the massive amount of indormation is the key. How a holo DV burner works is their business, it determines the layers if any based on the data to be recorded. Data arrays, like a speadsheet, will be the way.
And 3D reproduction was WOW as some guy's fist seems to come out of the screen right at you. Next it will be depth. You can fool the numan eye by multiplexing, but for it to work witout glasses is going to be a highly sophisticated LCD panel, there is no other way right now. It has been done an a small scale, and devices are actually on the consumer market, but they are not the size of a theater movie screen. The cost would be astronomical.
But then of course, like anything else, once all the R&D is done and it goes to mass production it will become affordable, if the economy doesn't completely collapse that is. And that is another factor, just how many people can afford it ? I don't care if you are rolling in money, it is not going to become mainstream unless people can afford it, which will create another mass market. If that doesn't happen, forget it.
