Pictures should be taken at the same instant.<br> Since I have designed 3D LANC Master I am curious how did they get synchronisation within +/- 3ms?

ben, if you want to see in 3D you need to “show” left picture to the left eye and right picture to the right one (taken form position which is “righter” than the left one). Pictures should be taken at the same instant.

Is it just me, or is this idea of using two cameras sort pointless if you can just do that. Couldn’t you just use an ordinary camera and then later on double what you capture with software?

Would be great to see a 3-d projector setup. I have made plans but not sure if it would work. Play each "eye" of the video synchronized to 2 projectors with polarized filters rotated 90 degree angles to eachother. overlap the images on a screen then use polarized glasses with the lenses at 90degree orientation difference to see the different images in each eye. Pretty sure this is how IMAX-3d works. I didn’t see any reference to how this would be used to simulate 3-d. Would be great to see a 3-d projector setup.

Did Sony have something to do with this? I was interested in viewing the demo video and in getting more info about the system. looks like the links are all broken.

I managed do it by crossing my eyes but I had to try very hard (though I would consider myself well trainied in eye-crossing. Anyone remember the "magic eye" books from a few years ago?). I guess there must be an easier way to get the 3D impression...<br><br> How do you watch those videos?
