Hi all,

There's a pretty good description of how it works, and how to make one yourself 
here:
http://forums.nvidia.com/index.php?showtopic=32547

I've never used one myself, and I personally feel that LCD stereo with a large 
f.o.v. on a single flat panel should be available soon (I think they just need 
to solve the polarization problem as some LCD TVs run at 120 Hz now). I think 
most people would prefer that too.

By the way, image inversion/mirroring can be done using Nvidia Windows 
drivers... but I'm not 100% sure about doing it in Linux as I've never tried it.

P.S: I shouldn't suggest these companies are over charging - though to me they 
seem to charge an awful lot of money given the components and skill/technology 
level needed to make them. Maybe I'm way off mark?!

Hi



Just looking at the diagrams, I don't think the glass is half-silvered - it 
looks like a large sheet of Polaroidâ„¢. It only needs to polarize the 
transmitted light from the vertically oriented monitor, since the reflected 
light from the interface between two materials (at least one of which has a 
refractive index) will be polarized in any case (that's why your Polaroidâ„¢ 
sunglasses let you see below the waves...). My physics is too rusty to 
remember, but I think the vertical monitor in this case needs to be polarized 
vertically, since the reflected polarized light will be horizontal.



No idea where you can buy large sheets of Polaroidâ„¢  though. 



IMWBW, though...

 Hi Andrew,



Just like the commercial systems, the glass is the only special piece of kit 
(which can be bought separately). The LCD monitors are just set up to display 
either left or right channel. If you ask me, I think these companies are just a 
rip off!
