        FOX used to run these ads that had a little, shitty picture at first, with (?!?) bad sound.. then it expanded to encompass the full glorious resolution and sound of... my regular TV.. to demonstrate the hi-def superiority. Made me laugh every time. People are impressed by HDTV when they see a real one, but how often is that?

        Back OT - does anyone know if this Sharp model 3D LCD does that half-brightness' thing when switching to 3D? I remember an earlier prototype used 2 LCD panes to simulate the effect, with the result being that one mode had half the brightness.

    • What did you expect the screen shots (shots of the screen, or computer grabbed shots of stuff on the screen which would be grabbed from the framebuffer anyway) to show you. Unless you have a 3D monitor and some software to interpret the shots in 3D all you would have seen was a really screwed up looking image on a display. Not worth it. The seems like a technology you have to see in real life to get the full effect.

    Well, they did a few years back anyway. I remember my friend challenged me to a game of Rise of The Triad in a booth at some theme park. The main attraction was that to see the game you got to wear these fancy looking 3D goggles. It was something like $3 a person, so I figured what the hell.

    That was the worst first person shooter experience I've ever had. Maybe the goggles weren't focused right, but I got incredibly dizzy from playing it and ended up not being able to do much at all. Maybe a slower game like Icewind Dale II would be more playable in 3D, but then, what would the point of that be?
    • IIRC Rise of the Triad was doomlike in that the enemys were flat bitmaps that changed based on your position. Plus, I also seem to recall being able to look up and down (unlike doom) but there was an odd warping to the view (although I may be recalling this from Duke Nukem). One more thing that may have contributed to your dizziness was the gait of the player while walking: it's been documented that the bobbing that doom did leads to motion sickness when wearing imersive goggles because you yourself aren't bobbing up and down. Regardless, I don't think it was a good game to try out.

      I had a pair of V-IOpener googles in 1997 (still have em but don't have the PC converter anymore). They were pretty badass, and the best game to play was Descent, as it had fluid movement, true 3D, and a natvie mode for the VIOs that would use the head tracker as well.

      • yes rise of the triads main fault was that it was more or less(probably more) hacked up version of the wolfenstein 3d engine. i don't recall it having up/down though. ultima underworld did have some up/down tilting, which warped the textures.

        besides, most people got sick of playing rott even without glasses, and it had nothing to do with the motion.

  • I'm not a rocket scientist, so if anyone more clued-in on the inner workings of monitors and 3d game engines could explain to me: can we ever expect something with a similar effect working on a CRT monitor?
    • Not without 3D glasses. The CRT can provide part of what is needed to produce a 3D effect(and must), but cannot do so without the help of the infamous flickering goggles.
      • Actually, after a brief look, it looks like they can. Since your left and right eyes are looking from a different angle, they can give each eye a different image "by controlling the path of travel of light from the display"

        I imagine you can't move your head a whole lot, though, and it would have to stay somewhere in the middle. You may even have to calibrate it to account for differing eye spacing. I bet it looks fantastics if you sitting in the "sweet spot", though.

        • The missing element from ordinary monitors(CRT or LCD) is a lens that makes it all work. The lens sits in front of the screen and lets your left eye see the odd columns of pixels, and lets your right eye see the even column of pixels. This lets the monitor display different pictures to each eye. Its similar to how those 3D posters at the movie theater work. You would need to buy the lens as an add-on(which would probably be near impossible since the placement needs to be so exact.
        • What would be really cool would be if the display can monitor the position of your eyes and modify the display accordingly, so as you move your head, or shift slightly sideways, it automatically adjusts so that you still get the perfect 3d display.
    • No. And yes. Certainly it cannot be done without some help, as the monitors don't have any parallax controls on them. However, they can certainly display tow images of the same scene, side-by-side. If you are good at the magic-eye type stuff, you will be able to see it. Otherwise, not. In fact, you could make it display magic-eye type pictures in real time, but that would be harder to see, monochrome, and more disorienting. Alternatively, you could wear red-and-blue 3d goggles, which makes your vision effectively monochromatic, but has much better 3d quality. Apple's prettydesktopwidget called Gerbils did this, IIRC.
    • CRT screens are blurred - even if you could add the extra layer to allow each eye to see different pixels, I'm pretty sure the effect wouldn't be all that good as the CRT will blur the two pixels together slightly - more so at higher resolutions.

      Fundamentally, this is new technology which won't be prevailant for years. By the time it happens, CRTs will be dead and buried. TFT screens are getting so good/cheap that the CRT will become obsolete over the next couple of years. The colour reproduction in some TFT screens [eizo.co.jp] is pretty much as good as CRTs and the resolution of others is way higher than that of a CRT. Combine the two with a good viewing angle and you'll never want a CRT ever again...

However, dedicating the color dimension to getting a 3D effect means the information densities you can get on the screen are somewhat lessened. Governments often spend a lot of money to get higher resolution elevation data. I know of several counties in FL that have 1m LIDAR for their entire county for flood control. Combine this with color aerial photography and you have a kick-ass visiualization system.

    Three dimensional vectors are composed of three numbers. 2d vectors have two. This much is obvious. What's slightly less obvious is that moving from 3d to 2d results in a loss of information (50%, in fact). If any of you followed the Shannon story from the other day you'd know that Loss of information = increase in entropy = heat. Therefore, when you hit the switch to move from 3d to 2d mode, your computer is going to get hot. Exactly how hot will be dictated by the amount of data on-screen and in-memory but my back of the envelope calculations here indicate that it will be roughly 3 GeV. Assuming a tower-sized case and 19" monitor made of metal and plastic, that translates to a 50F increase, which would probably melt the thing.

    So I call hoax.

      So when you forgot everything you might once have known about thermodynamics, did you get hot (because of loss of intormation)? Energy is conserved, entropy increases all of the time (pretty much...). It is not true that an increase in entropy will result in excess heat (energy). Nor is it true that simply ignoring available information increases entropy.
      And if your calculation of 1/3 = 50% is anything to go by, your 50F increase is probably way off anyway (even if the theory was sound)
      Entropy is often explained by comparison to disorder or loss of information, but it is neither of these, it is a function of state of any thermodynamic system. And it cannot create heat out of nothing.
    • Doesn't it also make sense that if your 3d/paralax generating display is in a separate element of the display that in order to switch to 2D, you simply shut off power to the element? I.E: less power == less heat.

    • What you fail to note is that as the information increases from 2d to 3d, it increases information, thus decreasing heat (by 50%). When it goes from 3d back to 2d, it only decreases information by 33%, so actually this story ties to the "little ice age" story from a few days back.

  • Does anyone know what the vieuwing distance must be to see the 3D effect?

    I think that "parellax-barrier" only works when you are right in front of it and at a certain distance from the screen. Else, for instance, the data for the right eye will meet the left eye, thus killing the effect.

    Can anyone confirm this?

    The cool thing about this product is that it's being marketed by a big company, namely Sharp, and not some no-name startup that promises to "revolutionize the world" but never gets its product to market. There's a much higher chance of actual success when a big company like Sharp is involved. From the site, they've also done the following:
    In 1973, Sharp was the first to successfully mass produce LCDs for use in electronic calculators. Since then, we have actively promoted innovation in display technologies, going from simple numeric displays to dot-matrix graphic displays, moving from monochrome to color displays, and on to full-motion video displays.
    Cool stuff.
    • Three years ago we purchased a similar display system from Sanyo. Their product never took off, so I don't think that a "big company" is the only requirement for it to take off.

      The problem with the Sanyo display was that, a) it had a very small "sweet-spot" in which you could actually view the stereo image; b) the technque of using a "paralax barrier" means that you halve the vertical resolution as each alternate column goes to only one eye; and c) you get slight visual artifacts as a combination of both of the first two points. Oh, and it is definately not cheap.

      Actually.. Sharp's press release is a fairly accurate description of the system Sony was producing back in '99. Good luck to them!

    This is semi-ontopic, but I wanted to say that Sharp make what are probably the best TFTs out there right now, so when this screen hits the market, it'll probably be a stunner.

    Sharp were also the first to produce 16" TFTs (one of which I own) which while double the price of the cheapest 15" displays, have a response rate of *half* what normal TFTs have, sRGB profiling, dual inputs (VGA/DVI), and a 1280x1024 resolution.. compared to the awful 1024 of most smaller TFTs. The 18" Sharp TFTs are pretty much the same, but larger, and oh so sweet. The 16" TFT is 104dpi. With ClearType, that leads to 300dpi (horizontal) goodness on text.

    Another thing Sharp has pioneered is 'slim bezel'. Most Sharp TFTs have a bezel of about 1cm, compared to the horrid 3cm+ bezels of most TFTs.

  • Let me enlighten you on a few vision science basics.

    Objects are perceived as the same distance away when light takes the same amount of time to traverse from each of the objects. Therefore you can imagine the world as a series of concentric spheres about your eyes, each sphere representing a "plane" of distance. In order to create the illusion of 3d on a 2d surface, it is required that the light traversal time be increased for those parts of the scene that are to be perceived as "deep". The problem is, while there are ways to make light go slower, the thickness of a sheet of paper (or even a computer monitor) isn't enough space in which to do it.

    Therefore, until some fundamental hurdles are overcome, 3d computing is only a pipedream.

      BZZT! Wrong. While the brain is a fantastic piece of biology, variation in lightspeed from objects that surrounds you in a room or outside are way too small for you to register.

      The brain calculates differences in angles from our two eyes to find out how far away an object is, as well as references to other objects for far away objects.

      Stare at an object and open and close your right then left eye. You will notice that objects shift from left to right as you do this. Objects closer to your eyes shifts relatively more than objects further away. For objects further away, a linear approched is also used, as in object B is behind A, therefore B is further away.

        anyway, what you've described (parallax) isn't our only sense of depth perception, but it's the easiest to recreate with a computer. the _other_ way we sense depth is a hell of a lot harder to recreate digitally - focus. we have to change the geometry of the lens in our eye to change focus from something that's near to something that's far. parallax displays will create a credible sense of depth, but it's still not entirely believable as both eyes are seeing the entire scene on one fixed-distance planes.
    • This is a moderately good description of part of how your head percieves sound as coming from a position but is completely irrelevant to how visual depth is percieved.

      One thing that will make or break this technology is how precise your head position has to be. It would seem to me that only an inch or so would put your left eye where your right should be. Not many folks are used to having to hold their heads that still while using a computer.

        I can only guess that you must have been a little kid to have missed out on Virtual Reality. Really, what is today Q3A and UT grew out of the want for better 3D graphics for those systems (I am not saying VR begat Quake, but it did influence the development of 3D engines, etc). HMD's, head tracking, glove input devices, 3/6DOF position sensors, etc.

        I have a wierd feeling - I mean, back then (and less so now, but still happenning) a lot of people were developing VR systems AT HOME - using 386/486 machines, Amigas, LCD TVs (for HMDs), potentiometers and wooden arms (for head tracking) and Powergloves to interact with 3D worlds they created (most of the time using Rend386 or other homebrew 3D software).

It seems crazy - but it is almost like you are one of a growing cadre of people who are TOTALLY unaware of this technology - and furthermore of the fact that today one can build a homebrew VR rig ULTRA-CHEAP, given some time, materials, and a little knowledge. Even if everything was bought off-the-shelf, it still would cost less than $5000.00 to do it. Buying used, or building, that cost could easily drop to below $1000.00.

        I am wondering if VR isn't undergoing something like the concept of a windowing desktop - I mean, the first such desktop didn't come about until 1969 (or was it 68?), but it took another 15-20 years before it really started to catch on, and another 10 still before it became ubiquitous - perhaps around, oh, say 2015 to 2030 I should expect VR to hit BIG, and it will be NEW and FLASHY!

      500x500x500pixels = 125 million pixels, or roughly 120MB of data per screen update. Multiply by 60 updates per second and viola! About 7.2GB per second of data. Current video cards (even high end) can't even handle this low resolution, slow, low color display. And the scale is exponential n^3. Your video card barely has 128MB of memory.

      A 15" display, 100dpi, 75Hz update and 32bpp is going to consume just short of one terrabyte of information per second.

      Eventually the display will contain the 3d processing hardware and its own memory, and the computer will send it directx 12 commands (or opengl, or cg, or whatever).

      But for situations where the data only needs to be viewed by a single user, these displays are wicked overkill. You've only got two eyeballs, take the 200dpi displays from IBM, sony's technique, and you've got a significantly better image at lower cost.

  • Then things can really sneak up on you.

  • still no affordable > 21 inch "plain" LCD's that can display high resolutions with no ghosting or color washout... ugh.
  • ...and possibly dangerous display device?

    This device [isdale.com], called TWISTER, was at the Siggraph 2002 - it consists of a drum made of of panels of LEDs that spin around the viewer standing in the middle. It was created by Kenji Tanaka, et al at Tachi Lab, University of Tokyo [u-tokyo.ac.jp]. I would imagine such a device could even be built to do full 3D, perhaps by using shutter glasses of some sort synched to the scanning of the LEDs. What would also be cool is to add a head tracker that could tell which direction you are looking in, and only activate an "arc" of panels such that the view went beyond your peripheral vision, but didn't wrap around, lessening the load on the computer driving the system (why display what you can't see?)...

    Anyhow, this image was taken by Jerry Isdale, a long-time graphics/VR researcher, who attended the show (sadly, I was unable to attend - can't afford it).

    The rest of his report [isdale.com] is also interesting, showcasing other 3D and VR technologies presented...

  • It says "3D/2D blah blah blah" but I see "R2D2 blah blah blah."

    God help us all.
  • I don't really think the 'switching' capability of this thing is really that impressive, considering the fact that all you have to do is throw everything on the same 'plane'... in other words, display the same image for both eyes. Not really much of an accomplishment.

    I don't even see how it could not be possible.
