[citation][nom]NivenFres[/nom]This kind of stuff has always sucked for me, since I don't have 3d vision to begin with. My eyes don't align right, so I basically am left with a dominant eye. I've even had surgery to correct it, but it didn't help restoring the 3d or depth perception. I keep seeing movie producers talk about making movies entirely in 3d, which worries me. Traditionally if I watch a 3d movie, even with the glasses on, I still see both of the stereoscopic images, since I basically am just seeing out of one eye. So while I think this technology is really cool, I hope it is not exclusive.[/citation]
I wouldn't worry about it. They can always make a normal 2D movie even if the movie is "shot in 3D". All that really means is that the movies are done with a sort of parallax camera setup (effectively, two cameras right next to each other to shoot the same scene from slightly different angles... it's replicates how our eyes work).
So, you can easily make a 2D copy of the movie by just using a single camera view. Believe me, there are plenty of people out there with "normal" eyesight who don't want to watch movies in 3D. A lot of people get vertigo and/or nauseated when they watch stuff like that.
