Umm no offence, but what that boils down to is "3D isnt real"dastardly said:Until they are able to comfortably make 3D that takes up your entire field of view, including peripheral vision, it will fail to go beyond an "interesting novelty." But the larger problem is that our senses aren't designed to work independently to that degree.Elizabeth Grunewald said:3 Ds Are Too Many For Me

What you see is only a single input. Granted, visual information accounts for about 80% of what we take in, but that doesn't mean our brain believes everything our eyes see. If you are to believe something out of the ordinary, what you feel and hear has to back up that unfamiliar input.
That means we've got to do a better job of making sure the sound backs up the sight, and that the sight isn't undermined by conflicting information (such as seeing the world around the movie in clear 2D. Really, is there a better way to do this than a helmet? Unfortunately not (yet). Even then, a helmet sends sensory information to your brain that says, "Dude, you're in a bucket. This isn't real."
Illusion relies on getting two or more senses to work together to fool the brain. 3D, unless you're sitting right up on it, is currently only engaging about 2/3 of a single sense.
Well, obviously. Of course its an illusion, or else theyd actually have something flying out of the screen. And actually, im fairly certain 3D works without sound or touch. Just look at those red and blue pictures, no sounds, no feeling, but still the illusion remains.
The 3D you get in cinemas (polarisation imagery) works solely with the eyes, by creating two seperate images. One of these images is in full colour, while the other is monochromatic. Different Polarising filters in the lense block one image, but not the other, and its this that creates the "jump out at you" effect. Like you said, its an illusion, simply a mis-marriage of information from the eyes.
