Re: Strip assembly panoramas with a digital slr -- for stereo etc

I dont understand how the Iz3d screen works but there is a a white
paper linked to their site but it is beyond me. there are two LCD
screens one on top of the other close together. One is black and
white and the other is colour and more normal looking. The black and
white screen controls the polarization of the light going through it
and controls the visibility to either eye of information encoded at a
subpixel level in the color image -- I think --

The screen looks like a normal (quite good actually) LCD screen
without glasses.

Ghosting means the left image say is visible slightly thru the right
lens even tho it shdnt be -- and produces a halo outline especially
against a light background.

Yes HMD= head mounted display. I made the stereo panorama background
for instance for this multimedia art piece a while back
http://www.icinema.unsw.edu.au/projects/prj_conversations.html
Video characters appeared to run around in 3d in the 3d panorama and
talk to you.
