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."

    Two Thumbs, Two Dimensions
    Roger Ebert is done talking about 3-D movies. Thank goodness.
    By Daniel EngberPosted Tuesday, Jan. 25, 2011, at 12:00 PM ET

    As far as Roger Ebert is concerned, the discussion about 3-D is over. "The notion that we are asked to pay a premium to witness an inferior and inherently brain-confusing image is outrageous," he wrote in his blog Sunday. "The case is closed."

    If that means Ebert will stop complaining about the medium, so much the better. For years now, the venerable critic has been griping that 3-D cinema is dim, distracting, and useless. And I mean for years: Even at the age of 10, young Ebert turned up his nose at Arch Oboler's stereo jungle adventure, Bwana Devil. (Deeply unmoved, was he, by the hails of spears.) That was back in 1952; more than a half-century later, he's still shaking his fist at the silver screen—I hate 3-D and you should, too! Professional obligations notwithstanding, Ebert doesn't want to see another movie in three dimensions. Ever.

    I've had enough of this persnickety crusade, marching, as it does, under the banner of pseudoscience. "Our ancestors on the prehistoric savannah developed an acute alertness to motion," Ebert writes, in an attempt to explain why movies like Clash of the Titans totally suck:

    But what about rapid movement toward the viewer? Yes, we see a car aiming for us. But it advances by growing larger against its background, not by detaching from it. Nor did we evolve to stand still and regard its advance. To survive, we learned instinctively to turn around, leap aside, run away. We didn't just stand there evolving the ability to enjoy a 3-D movie.

    OK, let's not quibble with the idea that human beings might have evolved to jump away from oncoming automobiles on the prehistoric savannah. I'm more interested in the two notions that follow from this dubious logic. First, that we ought not consume any form of entertainment that doesn't derive from a selected biological trait; and, second, that standard flat-screen cinema is somehow better suited to our genetic makeup—more natural, I guess—than 3-D.

    I wonder if Ebert really believes that the arts should cater to our Darwinian design, or that we're incapable of enjoying anything for which our brain wasn't delicately prewired. But in the event that he does, I'd only point out that such gimmicky and distracting art forms as, say, music, may very well be fiddling with our cortex in ways that have nothing to do with the fight-or-flight demands of a saber-toothed tiger attack.

    It's just as silly to presume that viewing a film in 3-D is any less natural—from an evolutionary perspective or otherwise—than watching it flat. For starters, the human eye did not evolve to see elephants stomping across the Serengeti at 24 frames per second. Nor are we biologically attuned to jump cuts, or focus pulls, or the world seen through a rectangular box the sides of which happen to form a ratio of 1.85 to 1. Nor indeed was man designed to gaze at any image while having no control over which objects are in focus and which are blurry. If all those distinctly unnatural aspects of standard, two-dimensional cinema seem unobtrusive, it's only because we've had 125 years to get used to them.

    According to Ebert, the 3-D effect brings in an "artificial" third dimension, which doesn't serve to make a movie any more realistic. In fact, he says, it makes an image seem less real, since under normal circumstances "we do not perceive parts of our vision dislodging themselves from the rest and leaping at us." Here he appears to be confusing cheesy, pop-out effects (which are used judiciously in the better—and more recent—films) with the medium as a whole. Yes, some 3-D movies do contain these gimmicks, but others do not.

      1. A car advances toward us by physically moving toward us, not by "growing larger". That movement makes it appear as if the car were "growing larger" AND the point of convergence of the image moving toward us. Both. It has been long proven that the simple appearance of "growing larger" is insufficient for depth perception, since people with just one eye will observe the growth effect but not the convergence effect, and they have no depth perception. This lack of convergence creating a lack of depth perception is used ALL THE TIME by 2D movie makers. It's how Frodo was made to look so small compared to Gandalf, for example. Frodo was further from the camera and thus appeared smaller than he would have standing next to Gandalf. The lack of 3D convergence made it appear that both actors were standing next to each other, and our brains told us that Frodo must be smaller.

      2. Of course we evolved to "stand still" when things approach us. We do not all "run away" when our loved ones approach, nor do we all run away when we are standing on the side of the road and a car approaches us. We use our 3-D vision to recognize which things are threats and which are not. I'm sorry, but a cartoon bear falling from a broken glider does not instill fear in most people. Roger Ebert is the exception.

      "we do not perceive parts of our vision dislodging themselves from the rest and leaping at us."

      I don't know about Roger Ebert, but yes, I do perceive objects in my field of vision as detached from the background all the time. They don't "dislodge" themselves because they weren't lodged there to begin with, and any 3D movie that changes from 2D (objects "lodged" on the background) to 3D is a poorly made 3-D film.

      I found the Yogi in 3D movie to be quite entertaining and the 3D effects did make it better than a simple 2D version. It helped focus the attention on the relevant action by bringing it to the front of the scene, instead of simply having a flat pair of cartoon bears dealing with a flat Mr. Ranger Sir and his hot love interest.

      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.

      That is factually incorrect. The Wikipedia article on depth perception lists clues used in depth perception, and the vast majority of them are monocular, not binocular.

      The two most important things are convergence and the physical sensation of focus. People with one eye (or with one eye closed) looking around at a scene can tell the difference between close and distant objects quite easily up to a certain distance, and less so the farther out you get. It is this aspect of 3D movies that causes problems. They are projected on a screen at a fixed distance, and as such, one of those depth clues (and arguably the more important one at the distances we're talking about) is missing entirely. You can get get away with using distance to create a perceived difference in size when you're using a camera because you can't physically feel the difference between a camera focusing at twenty feet and focusing at thirty. With a physical room and the human eye, you'll only get away with that illusion for a few seconds before your brain figures out something is wrong.

      Secondarily, the microscopic motions of your eye are enough to create a limited amount of motion parallax even with just one eye looking at unmoving objects. The natural motion of your head contributes to this. And so on. That, too, is missing from 3D projection.

      Finally, the human eye does not perceive things as a perfectly flat image in the first place. The rods in your eyes are much more sensitive than the cones, which means that they tend to pick up scattered light, whereas the cones basically only detect direct light. This means that a single human eye can perceive a difference in focal distance in a way that cameras cannot. This difference results in subtle fringing around real-world objects of differing depth that can provide further depth clues.

      So is 3D useless? No. Is it likely to fool someone into thinking it is real? Also no. There are too many visual clues that simply cannot be simulated through projection on a flat screen.

    According to Prof. Martin Banks, Professor of Optometry and Vision Science at U.C. Berkeley, the vergence-accommodation conflict should be kept at less than ½ to 1/3 diopters for the majority of a 3D viewing experience to avoid discomfort and fatigue.

    Which means if you are sitting ~16 feet from the screen, things can come ~10 feet out of the screen without you having any discomfort or fatigue. That is plenty of depth budget for most 3D movies. Thus, focus/vergence mismatch is not a real problem for stereoscopic 3D cinema.

    Now if you are ~20 inches from the screen, things can only come out ~3 inches out of the screen before potential discomfort or fatigue, so vergence/focus mismatch is a real problem for small screens. Thus personal gaming devices, computers, and televisions will need careful depth budgeting in stereoscopic 3D.

    "Super multiview" non-glasses 3D displays (generally with >32 views) where more than one parallax image is projected into your pupil at a time can force you to focus on the virtual 3D image where your eyes converge (this is how a hologram or the real world works, only they have nearly infinite number of parallax views).

    Looks like Ebert is really set in his curmudgeonly "new forms of media are trash and always will be" pattern. Guess what -- 2D cinema already violates many of the visual absolutes that our ancestors took for granted. This article complains that 3D separates focus and convergence, but 2D cinema already separated those from visual perspective, something that never happens in nature. We also evolved to have control over the plane that we are focusing on, which 2D cinema takes away. Even aside from depth cues, our ancestors only needed to perceive motion when they themselves were moving, there was no idea of sitting still and watching from a moving camera. I guess this "motion picture" thing will never catch on. It will always make some people motion sick from camera movement or give them headaches from the brightness and flickering.

    What is with the timing of this article anyway? The most successful film of all time, Avatar, is a flagship of 3D cinema. Maybe his next article should be "why the cell phone can't work, ever" because calls sometimes drop. Or maybe "why flat TVs will never catch on" because they don't have as deep blacks as CRT.

      Of course it does happen, for very distant sceneries (think mountain range a few dozen km from you, for example); they are for all intents and purposes a flat background - as far as focus, convergence, parallax are concerned. But we see their spatial structure, visual perspective works.

    Also: For people of middle age and beyond, presbyopia drastically limits the ability of the eye to change focus depth. Older people would probably find the images very easy to view. Better than holography, in fact, because they'd stay in focus at all "distances" while a holograph would require the viewers to adjust focus when they can't. B-)

  23. Fixed parallax and the 3D uncanny valley by tverbeek · · Score: 4, Informative

    Another problem with any fake 3D (i.e. dual images projected on a flat surface with binocular separation) is the fact that the parallax is fixed. When you view a truly 3D scene, your head doesn't stay still; it moves, even if just a little. You're not just sampling the scene from two angles, but from multiple angles. If you want a better look at a background object, you move your head to one side, and the image shifts a little. That's part of how your perception of depth works. Its much the same as why you need more than two speakers to create a realistically 3D soundscape (because we judge the direction of a sound in part by moving our heads imperceptibly). Even the most perfect flat-3D projection system cannot simulate that.

    This doesn't mean that 3D "doesn't work", of course. It simulates an approximation of a scene, just as 24fps 2D images approximate it, and B&W 2D images approximate it less realistically, etc. But it will always fall sort of a true three-dimensional viewing experience. And kind of like a CGI rendering that doesn't quite look real (the Uncanny Valley), it'll always fall sort of satisfying.

    Until we get real 3D projections. :)

  25. Motion blur by JimboFBX · · Score: 2

    If the only 3d I was exposed to was what I saw in theaters I would think 3d is inherently something that hurts your eyes. There's actually a couple things at play here:

    1. A lot of movie theaters have bad technology that results in unwatchable motion blur. Hey tards, for starters lets get both eyes IN SYNC. I suppose asking a minimum wage earning employee to make sure this is correct is out of the question, they can't even get their sound levels to be balanced half the time. Here's another fun fact: I get the same problem on my DLP TV when I watch a 3d movie on my PS3; I have to enable "movie mode" to get the motion blur to go away. I'm not sure if this is a TV problem or if they really recorded the blu-ray disk with one frame for one eye and the next frame for the other eye but I doubt anyone who isn't as tech savvy as me would figure this little thing out. It's subtle for one, no one wants to spend a bunch of money on a TV and PS3 and 3D movie then say out lout do everyone around them "hey does that look blurry to you when it moves?"

    2. The brain wants to control things when its in 3D. Despite having a lot of experience with 3D, being able to see stereograms without effort, and being able to play 3d games for hours on end, I don't feel that comfortable watching someone else play a 3D game. I get motion sick, I get eye strain, I feel things are blurrier or out of focus more often. I can't give a good explanation - maybe different parts of the brain are used when I play a game versus watching it.

    3. If you hear someone bitch about 3D then they probably wear glasses or contacts. Seriously, I'm not kidding. As a non-glasses wearer I can only venture a guess that the cause is that people's brains are actually compensating for something at all times without them realizing it. For example, on 3d previews the text floats about a foot in front of the screen. My mom couldn't focus on it. Given how often 3d floats that far in front of the screen I'd imagine I wouldn't enjoy 3d either.

    4. 3d is awesome for first person games. It is simply where it absolutely shines. There's no motion blur. You can set the depth to whatever you want. You are in control of the view so it feels natural. Real time strategy games can be kind of cool as well since it's like you have a bunch of toys in front of you fighting it out, but getting the depth to where it gives that neat effect without hampering gameplay is sometimes impossible if the game isn't already 3d ready.

  26. The instantaneous position of your big head by nigeljw · · Score: 3

    Depth perception is not viewing in three dimensions. If you want three dimensions go develop a light field display (http://gl.ict.usc.edu/Research/3DDisplay/). Stereopsis is achieved perfectly using two displaced cameras to view the image. Parallax is not perfect unless head tracking is used to transform the view frustum dynamically. Its like static depth perception without it. Everyone knows that dynamic is always better unless it is typing (this is a funny truth/joke, I hope someone gets it).

    There is a huge difference between the 2D to 3D conversion process to produce films and using a stereoscopic camera with dual cameras. Cameron used stereoscopic cameras to film Avatar, though I am sure he used some tricks to accentuate some scenes. Chronicles of Narnia used the conversion process, so all the characters are flat (I mean in regards to video, and not plot development), but the computer generated backgrounds have depth perception.

    Somebody else mentioned that depth perception is past its prime. I agree with him/her. This is the same technology of the 60s. Until head tracking is combined with depth perception, all of the binocular cues are not active. Convergence can be achieved with future technology. The only problem with the current technology is that sometimes bad editors overlay foreground scenes (from a green screen) and backgrounds with different depths of field. This produces a wonky image that our brain has trouble processing. The Gestalt principles should be law when editing 3D video.

    Nintendo DS does not use stereopsis (two images). It uses big object detection with a computer vision library to detect the position of your large head. It does not produce two separate images for each eye to view. It then transforms the viewing frame to account for the position of your head. So if you are looking out a window, you can poke your head around and see around the interior of the edges of the screen.

    I can't believe I had to read this article so I could comment on it.

    3D films remind the audience that they are in a certain "perspective" relationship to the image. It is almost a Brechtian trick.

    What nonsense, this is only because its feels weird wearing those glasses. And the glasses tend to be less translucent around the edges which causes a dream like effect similar to the blurred borders in scenes used in 90s TV to evoke a dream state, and in some bad movies.

    The shifting of convergence he is talking about due to the strobing from horizontal motion would be greatly reduced using head tracking (with depth perception) to perfect the parallax, but it is kindof difficult unless everybody has their own display with a camera on it. A side angle camera is required to perfect this technology, as using the size of your head does not really determine you head z position. The dynamic/instantaneous position of your head is important.
