Pixar to Release All New Movies in 3D
emcron writes "The Walt Disney Co. said Tuesday its Pixar animation studio will commit to 3-D by releasing all of its movies in the format beginning with "Up" in May 2009. Chief Creative Officer John Lasseter made the announcement in New York at a presentation of Disney's upcoming lineup of animated movies."

They use polarization separation instead. Two images, each with opposite polarization and with a slightly different viewing angle get to the viewer. Each lens of the glasses only lets in one polarization. For Beowulf they used right and left circular polarization. Which was surprising to me as I thought that circular polarizers cost too much to just be given away to moviegoers, but I guess those things are cheap now.

How it works? Light polarization. Each lens has a different polarization, so it only lets through the right light.
Neat trick: take modern 3D classes, hold them flat in front of an LCD monitor, and rotate them on the axis perpendicular to the monitor. You'll see the display behind dim and brighten as the lenses see it at varying angles.
Or you just get a projectionist in one of the non-3D theaters to film it. Just because they're releasing movies in 3D doesn't mean that they'll exclusively be in 3D. In fact, TFA even says so: "...Pixar movies will be released in 3-D and the traditional two-dimensional format..." Not that I'd expect anyone to bother trying to understand what they're commenting on.
This guy's the limit!
This technology isn't "newer", it's been around for decades.
I have a book published in the late 1930s or early 1940s at home called "The Marvels and Mysteries of Science", which is a very interesting read given our modern perspective. It has a complete section explaining how 3D movies work, including the polarization technique. Definitely nothing new!
Nice comment, but (a) 3D movies have no more (or less) flashing lights than 2D movies (b) No one reported seizures in 3D showings of Chicken Little, Monster House, Nightmare Before Christmas, Meet the Robinsons, Beowulf, etc. (c) "Wall*e" is about lovelorn robots, "Up" is about a geriatric superhero (d) Obama FTW
The filter that separates left/right pictures only works if you head is perfectly aligned (vertical). If you tilt the head, the polarisation of the pictures relative to your glasses will be tilted instead of vertical/horizontal and you'll see "ghosting", i.e.: each eye see both left/right frame instead of the correct one.
Modern glasses use circular polarisation.
Now the filter works whichever is the angle of your head. Clockwise and anti-clockwise polarisation remain the same even if you tilt your head.
Now the problem would be that the
But, you will still have a lot less problems because your eyes won't be receiving 2 image at the same time.
The worst glasses are the old anaglyphs (red/blue) : Only the intensity line up between your eyes, the colors are different for each eye and the result looks weird. Some people can use it and see 3D (I do), but most people only get a headache.
The only advantage of the anaglyph is that the movie work with existing technology. It's just frames with weird-colors. Whereas the other needs polarised filters on the projector(s)

Hmm, the thing about 3D vision is that it really breaks down quite quickly over distance. A result of this is that 3D pictures look pretty boring unless there are lots of things in the foreground, like people ridiculously pointing into the camera or throwing things at the audience. So the storyline actually may suffer in order to make the most of the 3D.
