polarized 3d glasses

[private81]

Hi,

I've got a special problem, at least I think so. Searching the web for three days, I didn't get anything. My firm will have a presentation. And we will deliver 3d glasses for the presentation. But blue and red glasses causes headache. We don't want our customers suffer from headaches. So, we reached a solution: polarized 3d glasses. But this time, there is another problem. With the 3d effect of After Effects, we can get 3d view when we wear red-blue 3d glasses, but we can't when we wear 3d polarized glasses. The working mechanism of these two kind of glasses are different, I know. I wonder, whether anybody has an idea, how we can solve this problem.

Thanks all for your interest and help...

Polarised glasses work only with polarised light, so you have to does this the procjector end (you can't use monitors for this effect).

The way I've seen it done, is by putting a sheet of polarised film infront of two projector guns pointing at the same screen. One film is rotated 90 degrees on the projector and your glasses, this then only allows one projected image to reach one eye, where the reverse polarised light will not.

To show you how this works, fold over your polarised glasses (assuming they are paper), you'll now find that they stop all light passing through the two eye slits.

You therefore need to produce your program as two slightly offset sources. Film footage is deliberately set up so there's a slight distance between two cameras, simulating image info of each eye. You can set this up quite easily in a 3D package with two cameras.

The red and blue method uses just one output source, as coloured light can be set up in the same image, where as with the polarised method, you can't output two degrees of polarisation in one frame.
