Just a quick one. Is it the way its filmed or how its projected? Thinking about going to see My Bloody Valentine 3-D and i was wondering if it came
out on DVD if i could buy some funky glasses and chill out on the sofa at home?
Cheers

I'm not 100% sure but don't think it will work on a standard TV at the moment. I saw something about in click on the BBC iplayer a few
weeks ago. There are a few companies working on a way to get it working on standard TV's but I think you need more boxes to make it work. I could
be wrong tho.

Rhod
Edit: found these might be worth a look

The filming is done with 2 cameras (or 2 lenses) side-by-side replicating your side-by-side eyes. Each has a slightly different view and your brain
makes it into 3D. The trick is then to have some way of only allowing each eye to see the appropriate image.
With the old B&W ones, it is played as combined red and cyan images, and the coloured lenses each filter out the other coloured image. You need
red and cyan glasses and it will work on TV.
Better colour films have the 2 images differently polarised and each glasses lens is a polarised filter. This won't work on TV.
With electrical displays like TV an alternative is to use alternating glasses and picture so eg one eye sees one picture then the other eye sees the
other one. Or you can wear electronic goggle things with a separate screen for each eye.

There is a method of filming/displaying 3D on a normal telly to be viewed with the red/green glasses, but it doesn't produce amazing results (not
much depth to it). It involves moving objects across the screen left to right or vice versa. Dr Who did a special years ago using the technique, lots
of panning shots and weird camera angles to try and force some 3D into every scene.
3D will be the next big thing in TV's, most of the major manufacturers have something in the pipeline already. I think a few of them have been
looking at lenticular screens.
It doesn't need moving objects. It just needs the 2 images. They like to overdo it though to emphasize the effect. There are plenty of
examples on youtube.
You need to get or make up some glasses with red cellophane in front of the left eye and cyan for the right eye. Used to be able to do it with
Quality Street wrappers!

The moving objects technique doesn't show two slightly different images with a red/green cast, so you can view it without glasses on without it looking like an LSD flashback. It's different from the stereoscopic techniques most people are familiar with.
Aha! Found it
