I saw the movie “Meet the Robinsons” in digital 3D. The story was so-so—better than reported in most reviews. The projection technology is new and interesting. It uses one projector, one lens etc. They project 144 frames per second, 72 for each eye. This is in contrast to 48 frames and 24 distinct frames per sec for normal movies. I presume they compute frame interpolation in the projector room. (They say only 24 distinct frames per eye per second; it seems only a matter of a bit more compute power to interpolate.) Alternate frames use circular polarization which makes tilting the head much less disruptive of the binocular effect. Maybe this is the spec.

Indeed the total effect is much better than I have seen before.

Now I am trying to denote a circularized photon in QED. I suppose the Jones vector is the way to go.
