looking around a bit I found out about Cameron doing his new CG movie in 3D.... But what I caught at the end:
"... I know I'm making a film for an audience. I can't just please myself." imagine the possibilities if GL gave a damn about you?
As far as I know, there are 3 ways of seeing a 3D film. I might be wrong and I might be forgeting some other method, but...
1- The red-green or red-blue googles. This was the first method used in 3d films. One projector showed a red-colored image, the other showed a blue or green image. If you look at a red image thru a red-colored plastic, you won't be able to see a thing, but the green or blue image will appear to be black. Same goes for the other color, which will be at the other eye. By using two different colors in each eye, the viewer would eventually have his eyes tired, and even get headaches. It was popular during the 50s but I don't think this method is used anymore.
2- The polarized googles. These came out during the 60s or 70s, and it's quite simple: each of the polarized glasses filter one form of light, in a way that if you put the two lenses together, light won't be able to pass thru. Both projectors are equipped with similar lenses, so one eye will only be able to see what one projector is showing. Of course, this method is not perfect and some light from the wrong projector can "leak" into one of the lenses, creating a "ghost" image. Yes, more headaches.
3- The "eletronic" way. This one is rare, and I haven't seen a movie in this format yet. Basically, you have googles with LCD lenses that shuts down one of the eyes at a time, 24 times a second. There are two projectors, and they are in synch with the googles, showing one image at a time, from the left eye perspective, and then from the right eye perspective. You'll have a nice, smooth 3D effect with this one, although I'm not sure about collateral effects such as headaches and tired eyesight.
