Do they work at all in CRT front projection setups? Anybody have experience with this stuff?

The red/blue one would
The polarizing glasses style would need 2 projectors, stacked with polarizing filters. Probably fed independantly with Left eye/ right eye information.

I'll add to what Jeremy said. Ray, there are three types of stereo at this point - anaglyph, passive, and active.
1) Anaglyph - Red/cyan or red/blue glasses - The oldest/cheapest way. No equipment necessary but cardboard glasses, but of course you completely screw the color gamut in the source material to gain the stereo effect. It's also hard to look at for long periods of time. The glasses can be practically free, and there no projector or screen modifications.
2) Passive stereo - Polarizing lense) is another way, but obviously as Jeremy mentioned you need stacked projectors and polarizing lenses, which burns nearly half your light output... making two projectors not even as bright as one. The glasses can still be cheap - but not quite as cheap. Projection has to be dual and polarized.
3) Active stereo - Powered LCD "shutter" glasses - Each eye in a pair of LCD-based glasses alternate between opaque and transparent, in synch with the display showing alternate views for each eye. Glasses can be wired or wireless RF or usually IR. You can do it with real-time computer-based 3D content such as OpenGL or Direct3D (DirectX), or you can do it with special pre-rendered content. Glasses are much more expensive, and you need an IR or RF emitter (or wires) to synch the glasses. No projector mods per se.
I only know of one decent consumer device to watch movies at home in 3D, but as far as I know it's never gotten any significant traction. It was a glorified line-doubler that worked with a standard DVD player and specially-authored DVD's. It's been around for at least 4 or 5 years, but I'd bet they haven't sold many of them. I watched some demo clips on a Runco-badged Barco 808, and it was pretty cool... But at something like two grand, I doubt many people think it's THAT cool.
Here's the site:

The real problem is the content. There just isn't that much. Is it worth much time/money, even if it was fairly cheap or easy (it's not) to watch a mere handful of movies?
If you do a few searches, I know there's been a few 3D threads over the last couple of years.

I knew you guys would come through. How the hell do y'all keep up with this stuff?. Those are the moveis I saw that were coming out that got me thinking about it. And I'm thinking now that's where those thoughts will stay. In the file for too much work/money too little reward. I still may try the Anaglyph option for giggles.
And AR, your avatars are freaking me out.

Why thank you Cleetus. That's a favorite Canadian actor of mine. Billy Van. He did a cool show in the 70's where he played just about every character. It was called the Hilarious House of Frightenstein. Vincent Price did the opening and closing credits.
How many Canadian boys remember that show?

The only decent 3 D presentation I've seen has been at Disney World. Forgot the name of it. I saw couple of 3 D demo's a CEDIA. They were not that great. I think sh*t flying off the screen at you is still gimmicky. Perhaps if they could make the ENTIRE image 3 D.

Honey I Shrunk the Audience at Epcot? The Muppets at MGM Studios? Those were also presented in Feel-o-Vision too. Feel-o-Vision, ha, ha! Anyone seen Kentucky Fried Movie?
Terminator 2 3D at Universal Studios was entertaining, though I don't think that's showing anymore. That was the REAL 3rd movie in the series! I don't care if Edward Furlong would have been drunk off his ass and doing lines of coke off Claire Danes's sweet ass between takes, you gotta have him play John Connor!

Taken from a review of Journey to the Center of the Earth (2-D and Limited-Edition 3-D) (2008) (New Line Cinema) :
| Quote: | | As the 3-D version has to be watched through red and blue filters, assessing video quality is rather besides the point. I will say that the 3-D effect works quite well. The only other 3-D Blu-ray title I've seen is Disney's recent 'Miley Cyrus & Hannah Montana: Best of Both Worlds Concert,' but I preferred this presentation a little more. The sense of depth in the middle ground is quite pronounced, with a noticeable false dimensionality that certainly delivers a 3-D experience. The far back is a little flatter, but the majority of the silly 3-D gags occur in the middle ground, so this isn't much of a probably. I only had issues with the extreme foreground, which tended to blur out objects right as they seem to poke you in the eye. Sure, it's a drag that full-color polarized 3-D is not yet possible on Blu-ray, but as far as red/blue anaglyph goes, 'Journey to the Center of the Earth' works quite well. |
