Umm no offence, but what that boils down to is "3D isnt real"
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.
I understand that you're new. Please, in the future, try not to grossly misread and oversimplify someone else's argument. Has anyone in this thread indicated 3D should "be real?" I know I haven't.
I know that, in fact, I expressly
stated it is an illusion. This is different from just being an "effect." Flashing lights would be an effect--they draw attention and make a big old show. 3D Imaging, as an illusion, is about
tricking the mind into thinking there is depth to a flat image--basically, that the world behind the screen goes further.
I'm fully aware of how it works, having worked with it myself. And there are several ways to accomplish the effect, anyhow. That's not the least bit what my post was about. My post was about how, for now, 3D is "new" (to those that didn't already have it growing up)... but as it stands it won't last beyond the "newness."
Because in order to be a
truly effective illusion, one that can outlast the novelty of the process, you need to
fully engage the field of view (otherwise people will get used to differentiating the 3D screen from the 3D periphery) and you need to ensure that other sensory data (particularly audio) backs up the "false message" that the illusion is sending.
Otherwise, it'll go from being an
illusion to simply being another bland
effect. It'll go from giving you a sense of depth within the movie... to basically being about as "effective" as watching a movie under a blacklight. Yeah, it changes how it looks, but not in any
meaningful way.
