I saw a movie in 3D Friday and was really impressed. One cool thing I noticed was that I actually had to change my focus between foreground and background as you do in real life. The theater charged $3.50 extra for the 3D version…I assume the projector is more expensive. I think you can keep the polarized glasses. They come in a sealed plastic bag and there’s a cardboard recycling box outside the theater where you can put them on the way out. I’m not sure how useful the glasses would be outside the theater. One cool thing to do with the glasses is to look in a mirror with them. Close one eye at a time and you can only see one eye at a time.

A little while back I saw a PC at Fry’s demoing 3D gaming. I thought I just remembered it using polarized glasses, but the ones on Nvidia’s site use LCD shutter glasses, which would be more expensive. I guess you need Vista/Windows 7, a compatible 120Hz monitor, and the shutter glasses. They have a list of compatible games. I was reading that it doesn’t work so well for some of these games, so it may not be ready for primetime yet. Anyway, it’ll be cool when it’s all working nicely. I wouldn’t buy any of this stuff yet.

Blu-ray is also planning to add 3D, but it’ll also require a compatible TV.

UPDATE: After reading this article on how theaters do 3D, I realize there is not much hope of using circular polarization on LCD monitors/TVs and that you probably always would have to use shutter glasses.
