3D Cinema Doesn't Work and Never Will

circletimessquare writes "Walter Murch, one of the most technically knowledgeable film editors and sound designers in the film industry today, argues, via Rogert Ebert's journal in the Chicago Sun-Times, that 3D cinema can't work, ever. Not just today's technology, but even theoretically. Nothing but true holographic images will do. The crux of his argument is simple: 600 million years of evolution has designed eyes that focus and converge in parallel, at the same distance. Look far away at a mountain, and your eyes focus and converge far away, at the same distance. Look closely at a book, and your eyes focus and converge close, at the same distance. But the problem is that 3D cinema technology asks our eyes to converge at one distance, and focus at another, in order for the illusion to work, and this becomes very taxing, if not downright debilitating, and even, for the eyes of the very young, potentially developmentally dangerous. Other problems (but these may be fixable) include the dimness of the image, and the fact that the image tends to 'gather in,' even on Imax screens, ruining the immersive experience."

  1. It worked well enough for me. by unity100 · · Score: 3, Insightful

    i watched avatar in 3d huge screen, and it worked well enough for me to be impressed by it and not to regret 15 bucks i poured into it. actually, i was thinking of going and seeing it again, but didnt have time due to work and life.

    really, i started to wonder why i am paying to cinema and widescreen, if we are not going to make use of the screen size advantage.

  2. not to mention the one-eyed among us by swschrad · · Score: 4, Insightful

    there are a LOT of people with one primary eye, and if the second one works at all, is only used to fill in peripheral data. a LOT of us. it has nothing to do with pinhead 3D glasses with are still as dorky as they were in the 60s. this is a cash grab by the entertainment industry to obsolete and sell-up a bunch of equipment before even the promoters wise up and start looking for the soft-OFF selection in the setup menu.

  3. Theory vs. Reality by DragonWriter · · Score: 4, Insightful

    Walter Murch, one of the most technically knowledgeable film editors and sound designers in the film industry today, argues, via Rogert Ebert's journal in the Chicago Sun-Times, that 3D cinema can't work, ever. Not just today's technology, but even theoretically.

    Since 3D cinema pretty clearly empirically does "work" for most reasonable definitions of the word "work", arguments that it theoretically cannot work are obviously evidence of either bad theory or pointless misuses of language, or both.

    Other problems (but these may be fixable) include the dimness of the image, and the fact that the image tends to 'gather in,' even on Imax screens, ruining the immersive experience.

    Experience, including experience of immersion, is subjective. If a sufficient number of people didn't find 3D using existing, non-holographic technology, to increase immersion when executed well, it wouldn't be a successful selling point.

    Some people don't like it, and it doesn't work well for some people (just like all the non-movie, non-holographic 3D tricks -- all of them work well for some people, and for any one of them they aren't comfortable for other people.) And, for that matter, things like shaky camera work -- for some people, that induces nausea and breaks immersion, for some people, it increases immersion and the sense of reality.

    Movies rely on lots of tricks of the eye -- whether 2D or 3D -- and the experience of movies is subjective. Arguing that something you don't like that lots of people demonstrably do somehow can't work even in theory is rather pointless.

      By "works" he means "replace 2D as the primary way movies are made".

      3D Cinema is a gimmick with novelty appeal. It will die when the novelty wears off just like it did the last n times it was tried. TFA suggests this will always be the case: that 3D Cinema can't be made into more than a novelty gimmick, unless we get something like holography instead of funny goggles.

    Yeah, it was a huge fad in the 50s, too.

    Nobody's going to deny that Avatar was a great experience in 3D. Problem is... every other 3D movie ain't Avatar.

    I was skeptical of his point myself, then I started paying closer attention and damned if he wasn't right.

    Of course he's right. Watching even the best-made 3D movies is tiring and distracting. If you don't believe it, try watching two 3D films back to back.

    And ultimately, even when done well, it feels like a cheap effect. I just don't believe the added value of having a guy riding a dragon seem to zoom over your head (but not convincingly) is not worth the added strain. Worse, in ten years it'll look embarrassing, and every director cares a little bit about how he's going to be perceived in the future. The guys who put all their effort into only putting out 3D movies are going to end up as marginal curiosities.

    So many of the big TV and game console people have sunk so much money into it that there's going to be an effort to push it long after its been rejected, however. It will end up the same way each previous effort to push 3D has ended up. The fact that it's even a matter of disagreement is proof that the current 3D technology will never become mainstream. When 5.1 surround sound came out, I don't remember people saying "it's just not convincing" or "it's not quite there yet" or "it causes fatigue". They just said "Wow. That's cool. I want more of that."

    I would love for there to be a really great way to portray three-dimensional space on a flat screen. I'm not some purist who thinks color movies were never as good as black and white. Hell, I still have an old quadraphonic stereo system down in the basement, collecting dust.

    And I was surprised when I found myself enjoying Avatar more as a cinematic experience watching a good Blu-ray copy on an excellent 1080p screen than I did seeing it with a pair of special glasses at the theater when it first came out. I could enjoy the story and the visuals without trying to convince myself that it "looked almost real with branches flying over my head". And I didn't feel slightly woozy with a headache when it was over watching it in 2D.

    Funny, for everyone unanimously agreeing about how great 5.1 is most people are still using stereo. That's right. 5.1 setups are still unusual. Yes, they are out there, but just as wearing the glasses are not worth it to most people, neither is setting up a 5.1 system, and having to sit in the 'sweet spot' to get the proper effect.

    I'm not sold on 3D any more than I am on 5.1 audio, but just like 5.1 audio, the cost of including it is so small that the manufacturers might as well include it for those that want it. Don't expect 3D TV to go away. The will already run at a frequency that supports it, and including the electronics to transmit a signal to glasses every other frame is trivial. There is no compelling reason for TV manufacturers to leave it out. Add to that the fact that pretty much all video games, and an good many of the computer generated movies are created in 3D and down sampled to 2D, so 3D versions are basically free, 3D is likely here to stay.

    The plus side, is that just like using stereo instead of 5.1, playing media in 2D instead of 3D will be completely available.

    Most use stereo because we have 2 ears... and therefore only 2 channels are necessary for 3D sound. 5.1 is a gimmick.

    Stereo forever.
