What, you mean like the cheap, disposable glasses a lot of cinemas are using now?
I do wonder why that isn't possible in the home...
Actually though, it is; A digital projection setup can pretty much match what the cinemas are doing... It's not even that difficult.
It's just... Digital projection systems are somehow less popular than large screen TV's, even though for a given screen size, it's probably cheaper.
Oh well.
i think you need a specifically produced 3d projector dont you?
but yeah if you have the space for a screen, or a suitable blank wall a nice HD projector would an alternative to a TV. would mean watching tv with the light off all the time though, unless there are ones bright enough to be used with the light on?
sony produced a 3d projector already. still uses active shutter glasses rather than passive polariser glasses though, made me facepalm pretty hard when i read about it.
surely a single polarising LCD shutter on the projecter is cheaper than two blanking LCD shutters per viewer. hell the tech had already been produced for cinemas, in fact the principle was already in use for your basic 7-seg LCD calculator or watch display. it was just a case of fitting it to home projectors.
Yes, you probably do need a specially produced 3d projector.
Then again, I've seen hardware hackers make 3d projectors (one was made for use with second life). All it takes is 2 normal projectors, placed so that the images they project overlap.
(I'm sure you could figure out a way to do it with 1 projector, but for improvised equipment, that creates a lot of complicated timing and video signal alterations. Using two projectors, with a PC, it becomes almost as simple as a dual monitor setup.)
All the technical modification it took, was placing a polarising filter in front of each projector, aligning them so the images are the same size, and project to the same location, and then making sure your polarised glasses correctly match the polarisation of the projector images for each eye.
Hardly difficult to create, if a little expensive in that you need 2 projectors. (polarising filters cost next to nothing by comparison.)
If I had the equipment, I'd probably try and hack one together from the 3d cinema glasses I've got lying around.
To be quite honest, I think using shutter glasses with a projector is a stupid idea that can at best be because they want to have the same glasses for all their 'tv' systems, but in reality sounds like an excuse to use expensive glasses even when they aren't needed.
