thanks for watching tech wiki click the subscribe button and enable notifications with the bell icon so you won't miss any future videos 3d video it's one of those things that were constantly being promised is going to be better than ever from Hollywood blockbusters that you have to pay an extra seven bucks to see in real d2 the Nintendo 3ds which force without even needing those dorky glasses but the consensus among moviegoers and gamers alike is that current 3d offerings are more than a little bit underwhelming with words like unnecessary distracting and sorry nausea-inducing uses fraud the experience so why is it in 2017 nearly a hundred years after the first 3d feature film hit the theaters that 3d consumer technology is still so terrible well it turns out that the human brain is pretty hard to trick into thinking that something is actually real and immersive when it's really just a projection on a flat surface you see when we look at an object in the 3d space of the real world our eyes are just trying to focus on that object alone but we're looking at a 3d movie or a video game our eyes need to stay focused on the screen while they're simultaneously trying to focus on the object now because the virtual objects look like they're somewhere between the screen and our faces it's not something we're all used to doing in the real world and it's a very tough problem for our brains to figure out how to resolve and of course to sharply-defined edge of the screen doesn't help the sense of immersion either meaning the resulting 3d image looks less than realistic and that's also where the queasiness I mentioned earlier comes in so let's talk about some of the problems that specifically affect movies the real D branded 3d system that you commonly see in movie theaters works with dual projectors and glasses that polarized light in different directions for your left and right eye so each I guess is slightly different image to fool your brain into thinking that it's seeing something three-dimensional but unfortunately filtering out half the light has led to complaints that modern 3d movies not only unconvincing but they're also way too dark to enjoy so given the price a little buyer's remorse is understandable home solutions have also been fraught with problems requiring bulky power glasses which you can learn more about right up here very expensive television sets pricier copies of the same movie or at the very least a halving of the vertical resolution so that each eye only sees what it's supposed to oh yeah and everyone watching has to look like a dipstick there's also the minor matter of how these movies are produced in the first place some films are produced specifically with 3d in mind a duel and stereoscopic camera rig that can capture 3d images natively is neither for the best results avatar was notable example of this done correctly and animated films can have this effect applied with virtual cameras after the fact now although doing this doesn't eliminate all the problems associated with 3d it generally makes for a more pleasant experience than the many other films that were actually shot in 2d and chizel ii converted to 3d later on you can think of this a little bit like how video games pour it from console to PC are so often disappointing which you can learn more about up here well except a little worse and speaking of games what about the 3ds well thanks to Nintendo's use of a parallax barrier which is a series of slits placed over the back light illuminating some pixels towards your left eye and some towards your right eye there are no brightness issues and you don't need glasses but unfortunately the physical slits can severely restrict viewing angles which is why the 3d effect doesn't work nearly as well if you tilt your screen more than just a little bit when you combine that with the system's low resolution and lower refresh rate than what you get at the cinema it isn't surprising that many people were instead clamoring for a clamshell style 2d s which of course Nintendo ultimately did give us and desktop PC gaming and stereo 3d had a similarly short 15 minutes of fame in the form of Nvidia's 3d vision which required a supportive islander a support a graphics card specific classes and validated games for the best experience so is probably not surprising it didn't take off now with that said with the rise of high quality VR headsets like the oculus rift and HTC vive consumers are beginning to enjoy 3d experiences at high refresh raised without flat projection screens that throw their entire field of vision helping to alleviate some of the issues we've discussed but with VR tech still attempting to catch on with game developers and other content providers I do wonder if we just be better off waiting for someone to invent a real-life version of the Star Trek holodeck if we really want convincing 3d and speaking of three dimensions are you ready to add a new
