Using 3D Vision

Wall-Sized 3D Gaming With Nvidia 3D Vision
By

3D Vision is somewhat simple to use, and in many cases, tasks are handled automatically. However, there are a few things to keep in mind.

Operating the 3D Vision IR emitter

You'll need a clear line of sight to the emitter from your seating position because it sends a signal to the 3D Vision glasses that synchronizes them to the display. It won't work if the emitter is behind you. The good news is that the emitter outputs a strong IR signal that works as far as 30 ft. away, so a number of people can use the same emitter at the same time.

There are two controls on the emitter: an On/Off button for the 3D effect and a depth wheel at the rear. The On/Off button is self-explanatory, while the depth wheel increases or decreases the depth of the 3D effect. The best way to understand what it does is to try it out. Simply set it to taste.

Launching a Game

Once you have enabled 3D Vision, it will automatically become active whenever you launch a 3D game. 3D Vision will show you a heads-up display with information about how well 3D Vision works with the title, if any information is available. Typically, the overlay will give the game a rating such as “Good” or “Not Recommended” and describe the in-game settings you might want to tweak to minimize 3D anomalies, if possible. When you're done examining this information, you can make it disappear by hitting the Ctrl-Alt-Insert keys.

The Depth Issue

This brings us to an unpleasant, but workable, issue that we encountered: a lack of apparent 3D depth in some games when using 3D Vision.

The 3D depth hinges on two factors: separation and convergence. Both of these factors must be set properly for a good 3D effect. Nvidia has supplied a very convenient separation control on the 3D Vision emitter (the depth wheel), but the convergence control is much harder to find. The setting is actually disabled by default and must be enabled in the "Set keyboard Shortcuts" pop-up menu in the "Set Up Stereoscopic 3D" panel of the GeForce driver.

In most games that Nvidia has profiled, it has created a default convergence setting that facilitates a reasonable 3D effect. Unfortunately, there are some games for which Nvidia has not created a profile, and if the default convergence setting isn't quite right for the game engine, the 3D effect will be poor, regardless of what the depth wheel is set at. Naturally, this is something that Nvidia has the power to affect with driver updates, and the good news is that the company continues shipping newer software to keep 3D Vision up to date.

Another issue with the convergence controls is a lack of user feedback. Increasing or decreasing convergence might have a very subtle effect for a long time before you notice any difference on screen, so some feedback about Nvidia's 3D Vision HUD would be appreciated here. Essentially, we think that the critical convergence control should be enabled by default and that there should be some user feedback when the controls are operated.

As for separation, the depth wheel on the 3D Vision emitter doesn't allow us to increase the apparent 3D depth past an arbitrary value that we feel is too shallow in some of the games we tested.

3D Vision allows a maximum depth setting based on the size of the display you are using and the display size is hard-coded based on your 3D Vision-compatible device. In the case of the H5360 projector, though, the screen size is variable--there's a huge range of possible screen sizes. Nevertheless, the 3D Vision driver decided on a 110" screen size, and that's what we had to live with.

Traditionally, Nvidia's 3D drivers have offered screen size settings, and because the maximum depth is based on the screen size, it could be used to manipulate the maximum depth. A smaller screen size setting allows for a larger apparent maximum depth. Unfortunately, the new drivers do not allow the user to manually select the screen size for a known 3D Vision display. Nvidia could easily fix this issue for everyone by allowing advanced users to set their own screen size in the driver panel, and we requested that in our feedback.

    I'd rather wall sized 1080p playback than wall sized 3D playback. = )

    I would love to have a 3D system like this, unfortunately it's nCredibly expensive...

    What about DLP 3D? the projector supports it, DLP-link glasses are cheaper and dont require a transmitter like the nvidia glasses.

    "The whole experiment consisted of about $2500 worth of hardware and software, NOT including the PC driving the displays."

    I cringed.

    I own a acer h5360 and I agree, it is awesome watching 3d movies on it. 1080p? Dont even notice pixellation at 115 inch screen. 720p is fine and at a great price. 1080p 3d projectors will be extremely expensive for average consumers.

    Is this projector better than the Mitshibshi 73" 1080p dlp for $1100?

    Im sorry, but 3d is NOT expensive. The acer 5360 can be bought for as low as 580 and the nvidia vision glasses kit can be bought for as low as 150. That is under 1,000... less than the cost of a 3D TV.

    Interesting read, but ultimately all this 3D talk leaves me with a big question. I have a PS3 and if I upgrade my PC to a 3D vision enabled PC is there a projector (perhaps the one discussed in this article) that would allow me to enjoy the 3D from my PS3 and my PC? I understand if I would need a switch between devices or manually switch cables. I know NVIDIA is working on a 3DTV play tech that let's you use the glasses of 3D enabled HDTV to enjoy NVIDIA 3D Vision, but is there a similar option for projectors?

    ATI/AMD will make it a lot cheaper without proprietary hugely expensive crap like nvidia.

    Saddest thing in the review: "and the software developers we've talked to have indicated that the dual-projector option is too fringe to justify development."

    D-bags once again focusing on their limitations rather than options.

    Glad I didn't waste my money on that 3D upgrade for PowerDVD or others until they get their act together to support both methods.

    It's obviously already possible as shown by JVC last year (see end of clip);

    but once again leave it to the small minded accountants running the companies to keep it held back.

    Nice look as always though Don. :sol:

    That's for one viewer, and then it's X amount for each additional viewer to have shutter glasses, expensive if you have friends, cheap if you're a loner.

    Polarization is the way to go for a bunch of people.

    I actually have a setup like this but I used a optoma GT700 and did a little messing with drivers to get the nvidia glasses to see it.. I don't really see a whole lot of "3d" though I guess maybe my eyes don't work well with the system.. I got to say though having a 135' screen to watch movies on is fun..

    Well Nvidia's 3DTV Play will offer the same thing. HDMI 1.4a compatibility, no need to buy the Nvidia Vision kit, works with glasses provided by the display etc.
    It's odd, that article you posted doesn't mention that.

    Most Cinemas I have seem do not use 2 projecters to display 3D movies they use a single digital projecter that displays alternate frames, the Dolby system uses A spinning filter wheel betwean the projectors lamp and Imager, it alters the light up and down in frequency synced to the proper frame and passive RGB filter glasses allow only the corect eye to see the corect image (no special silver screan required because the light is not polerized ) RealD uses a switching circuler polarizer (called Z screan ) placed in front of the projecter and synced to the proper frame this system like all polerized systems requires a silver screan to mantain polarization of the image and is viewed with cicular polarized glasses (inexpensive) both systems use a single projecter and alternating frame sequence of the image projected, and passive glasses there are Active glasses systems as well but they are less comon.

    look up the gt700 its 720p but the nice thing about it is that its short throw. So you can put it in a 10x10 room and still get a really large picture..

    Lets not forget that HDMI 1.4a does not have a mandatory standard for 3d at 1080p60. The HDMI chips are just too slow to handle the bandwidth. It's limited to 1080p24, 1080i60, or 720p60. So 3d Bluray playback will be fine on HDMI, but 3d gaming will be very limited on HDMI.

    heads up for 3d vision..bt nVidia sucks for making it only geForce card compatible..
    ATI cards would have given lot bttr results
