Stereoscopic Technology

GeForce 3D Vision: Gaming Goes Stereo
By

As the word suggests, a stereo display system presents two images: one for the right eye and one for the left. Combined, they create the appearance of depth. Now, there are a couple of different ways to present stereoscopic images, both of which require eyewear.

In a passive configuration, glasses with polarized filters are used so that the left and right images are only seen by the intended eye. Because the glasses don’t contain any electronics, they’re vastly cheaper and work great for shows like "Honey, I Shrunk The Audience" at Disneyland, where a large group of people has its eyes on the screen.

An active system, in contrast, leverages electronics built into the glasses themselves, which trigger LCD shutters in rapid succession to achieve the same stereo effect. Although they’re more complex (and thus, expensive), an active system delivers more resolution per eye and a wider viewing angle than passive glasses do, according to Nvidia. Like the Elsa Revelators we first experienced 10 years ago, Nvidia’s GeForce 3D Vision kit is consequently active as well.

The GeForce 3D Vision Kit

But priced at $199, we’re a long way away from the TNT2 bundles seen a decade ago. The standalone kit includes wireless glasses, an infrared emitter responsible for communicating with the glasses, a DVI-to-HDMI cable used with DLP HDTVs, a pair of USB cables for connecting the emitter and charging the glasses, a VESA three-pin stereo cable used to sync with a DLP, a protective pouch, and a pair of nose pieces that offer a slightly different fit.

Active shades, which communicate wirelesslyActive shades, which communicate wirelessly

The glasses themselves certainly aren’t stylish, but they won’t land you on Page Six of The New York Post, either. More important, they’re actually light and comfortable, despite the electronics contained within. The ends of each frame are rubberized for a snug grip on the sides of your head, and if the stock nose piece doesn’t fit well, one of the two others should work better. Turning the shades on is as simple as pressing a small power button on the frame. And after 10 minutes of inactivity, they’ll automatically shut down. It takes three hours to fully charge the built-in battery and 40 hours of continuous use to fully drain them. We weren’t able to get 40 hours of testing in, but after going through seven games, we’re still on the first charge and they’re holding up well.

Nvidia's IR emitter, with a 20-foot rangeNvidia's IR emitter, with a 20-foot range

Control over the glasses is exercised by an included IR emitter, which has a 20-foot range and supports as many sets of shades as you feel like buying. The front of the transmitter sports a simple on/off button. The back sports a USB port that hooks up to your PC, a power indicator, a VESA cable port (in case you use the glasses with a DLP), and a thumbwheel to adjust depth (eye separation). By default, the depth setting is 15%, but we found that, in certain games, adjusting depth up or down (usually down) improved the experience.

Everything else in the package is complementary. USB cables are used to attach the IR emitter and to charge the glasses between uses. The DVI and VESA cables are only necessary if you use a DLP TV. And the storage pouch simply protects the glasses, which are actually glass and can be scratched if you leave them lying around.

    Interesting, but I'm surprised that this came out before an updated and finalized GTX295 review.

    nV's recent flurry of 3D stereo-vision and Charlie @ the InQ's pre-emptive bashing of it have been interesting, but it reminds me of Matrox's wonderful surround-view feature, which is great, but it's still niche and will remain so.

    Not my cuppa, but at least the tech is moving forward so who knows about the future.

    I'm one of those people who see the rainbow effect on Gen3 DLP screens with 360hz colour wheels, so I have a feeling these new glasses won't improve the headaches anymore than the faster wheel solved my rainbow vision. Now synch some shutter glasses on a 480hz plasma... ;)

    Nice article, but you're forgetting about something...Pc's are not only used for gaming, and if NVidia wants to make this really popular they MUST find a way to make movies work with their glasses.Currently there are very few titles that are in 3D, most are old, and the new ones are expensive, and so far converting a regular movie to stereoscopic 3D is almost impossible, and the quality is not what you'd expect. Also...besides providing their own hardware and a new Vista compatible driver, what did NVidia came up with that surpasses all the other 3D shutter glasses on the market(eDymensional..etc.), giving to account that all the titles you tested work with/the same(look,FPS etc.)with any stereoscopic glasses?

    Grape,

    It's coming. I sent all of the hardware to Thomas, who has a second GTX 295, which means we'll be able to deliver benchmarks of two 295s versus a pair of X2s and so on down the line. I'm over at CES, so all of this had to be finished up before the show. Should be worth the wait. I'm looking forward to see what four-digits worth of graphics horsepower is capable of, to be sure.

    I had the chance to check out Nvidia's competition tonight at the show and am currently working on a news story about it. Not. Impressed.

    This brings be back to the Asus V6600 GeForce Deluxe card I got in 1999. At that time, the 'Dagoth More Zoological Gardens' with the VR-Glasses was the most awesome sight I've ever seen on a PC. This worked with Ultima9 as well as a nice surpirse :) 

    I'm surprised I havin't seen (mainstream) 3-D displays without glasses yet. I've seen some samples of this in the past with small screens.

    LCD shutter glasses again??? Really? Yawn. Where are the glasses that beam images directly onto my retinas or even a set of lcd glasses that are actually 2 tiny HD monitors but still light enough to wear comfortably...

    I need to point out an apparent error in nVidia's statement regarding TV's... I purchased a Samsung 40" LCD TV (Model number LN40A650) just prior to the holidays that has 120 Hz HDMI ports (4 of them) AND has 120 Hz refresh rate. So there ARE large screens out there that should be able to support the 3D technology.

    I would guess that it fits over glasses.

    120hz processing isn't enough. The screen must be fast enough to DISPLAY 120 distinct images per second, and it must be at a precise rate, so the shutter glasses can sync properly.
    The varrying response times of LCD panels, depending on colour etc, will prevent a smooth moving, stereo image.

    Does it work with other 3d capable apps. Scientific stuff, 3d desktop, media player visualizations/screensavers etc?

    Wow it's been a while since I have seen Elsa mentioned. They made some really good video cards back in the day.

    so what, Tom's is telling me I need 2X 295 and then everything is good right?

    darn! I think I'll have to stick to a red-blue and rad racer

    So you're saying the problem is based on the fact that the display is an LCD display? Then why were two LCD monitors listed as compatible?

    The TV I purchased lists a 4ms response time for the pixels. That translates to approximately a 250 Hz refresh rate. The requirement for these glasses is 120 Hz which means it is less than half of the TV's rated capability. Are you SURE it's not going to work?

    It's god to know that if I ever have enough money I can get something guite interesting to my desktop! Even if this will be a niche solution for some time, at least it's nice to know that there is something that you can put your sli cards really to do something usefull. But I really hope that even this feature should be "open" standard to all GPU makers...

    looking from nvidia's perspective, this feature must work really good in order to sell more GPUs since this obviously requires SLI more than crysis.
    I wonder how amd's stereo solution will work, probably performs almost the same but cheaper. :)

    3D is the next big thing in movies after digital projection and HD. Check out Wikipedia's list of future releases in 3D for more info.

    "and you’ll need a fairly potent graphics subsystem in order to really enjoy it. "

    You people always complain about performance issues... well gotta tell you that things aren't so black and white... well not so black anyway :p 
    I have a HD4870 video card, a phenom 9950 processor and 5 GB RAM @ 667Mhz... and I can play Crysis with all the settings turned to VERY high at a 1680x1050 resolution with a playable frame rate. So what I'm trying to say is that with a fairly standard gaming rig you can play the latest games with all the settings turned on/set to very high... just imagine what you can do with just a little more (a 4870x2 instead of the simple 4870... or a tad more ram)

    I used a pair of shutter glasses a long long time ago. They were pretty cool, but far from perfect. One of the issues I experienced was ghosting (a faint image of what the opposite eye was seeing). This was on a CRT. I would expect such an affect to be more apparent on an LCD.

    So my question to the author is, was there any noticeable (or negligible) ghosting during your tests?
