I have a silly question.

In my country, the glasses they give us to see 3D movies, namely Avatar, don't work with batteries I think. They don't "flash" in my eyes. Just regular futuristic glasses.

Why do those Nvidia glasses work on batteries?

I know one thing is movies, and another is game's with frame rate drops. But still. I don't get it why the 3D cinema glasses "don't work"(?) for 3D computer games.

In cinemas, they put a light polarizer in front of the projector (which changes the polarization of every other frame). Each lens in the glasses then filters for one kind of polarization, so that each eye only sees what it's supposed to.

With Nvidia glasses, the images for each eye have the same physical characteristics, so you need shutter glasses to actively filter each alternate frame for each eye.

You could have the cinema system at home, but you'd have to put a huge and expensive light polarizer in front of your plasma... not a good idea.

 

True, however there are polarized monitors and game drivers which work from home with the polarized glasses. IZ3D offers this tech at home for gaming...

The monitor actually has 2 lcd panels projecting different light frequency.
