Nvidia GeForce 3D Vision vs eDimensional 3D Vision

June 22nd, 2009 · 1 Comment · GeForce 3D Vision

3d-vision-vs-3d-vision-1


If you remember I’ve written that the shutter glasses designed by Nvidia for the GeForce 3D Vision are way looking much better than previous such products, but here I made some pictures so you can even see that for yourself. In the left of the images you can see the glasses from Nvidia and on the right are eDimensional’s wireless 3D Vision glasses, the difference in design is clearly visible…

Besides being more good-looking Nvidia’s glasses are also more comfortable and adjustable to the needs of different users, not that Edimenstional’s glasses don’t have such ideas embedded, but their design is still not that good. By making shutter glasses you need to design them so that they not only don’t look weird, but also to be comfortable even when wearing them for longer periods of time…


3d-vision-vs-3d-vision-3


Not that the shutters on eDimensional’s glasses are almost square in form, where as the glasses from Nvidia are wider and this is because of big difference in time when the products were designed and first released on market. eDimensional’s 3D Vision glasses are quite old product, as far as I remember released 5 or even more years ago when the CRT displays with aspect ration of 4:3 or 5:4 were used almost everywhere. But now most of the new displays are widescreen with aspect of 16:10 and 16:9 so having wider shutters is not only good, but is actually a requirement in order to have the wide filed of view needed for the new LCD monitors. Another big difference is that eDimensional’s glasses use 2 lithium batteries for power that are not rechargeable and you have to replace them from time to time, although they last longer than the rechargeable battery available in Nvidia’s glasses. Anyway with up to 40 hours on a single charge and an easy and widely used mini USB connection for recharging there is not much to complain about Nvidia’s 3D Vision glasses.

Here I have not provided pictures of the IR transmitters of the two types of wireless shutter glasses, but you should know that eDimensional’s solution does not rely on USB connection and actually requires you to connect it between your video card’s output and the monitor you are using. And you can already guess that it utilizes an analogue DSUB15 video connector in order to do that and the drivers are supposed to do everything else. Now, when talking about drivers, eDimensional had a bit of an advantage, becuse they used their own drivers that were compatible with both ATI and Nvidia video cards, although the glasses also worked with Nvidia’s old stereo drivers. Currently eDimensional’s drivers are quite out of date and not very usable, and the newer stereo drivers from Nvidia no longer support them (along with many other older devices!). If you own eDimensional 3D Vision glasses or any other shutter glasses you may try to run them with IZ3D’s driver, but the success rate depends on a lot of factors and the results will still not be as good as when using Nvidia’s 3D Vision. Not to mention the fact that if you intend to use the IZ3D driver (besides just quick testing) with something else than their 3D displays you’ll have to buy a license and the shutter glasses support that is currently available is still not very good, so don’t get your hopes too high.

Using Anaglyph Glasses with 3D Vision Driver

June 22nd, 2009 · 30 Comments · Anaglyph Glasses

With the 3D Vision drivers you get a nice bonus, or at least you may call it like that, because apart you’ll also get free support for anaglyph 3D stereo mode. Or said with simpler words you’ll be able to play with a depth perception using your normal computer system and a pair of anaglyph (those plain old red/cyan paper or plastic) glasses. Of course using the anaglyph mode will not provide the same impressive and great looking depth perception in games and 3D applications, but will give you a nice upgrade when gaming, because you’ll be able to at least have some 3D effect. The requirements that the anaglyph mode has to you is to own a pair of anaglyph glasses and it seems Nvidia will start offering some of these very soon, but you can also get them from other places pretty cheap. The only other thing you’ll need is an Nvidia-based videocard, preferably a faster one that can provide enough frames for comfortable playing. There is no limit to the supported GPUs as when using the 3D Vision shutter glasses, and also there is no need to have a special 120Hz display, because anaglyph mode can work just fine with your normal CRT or LCD monitor. Just have in mind that the 3D Vision drivers require you to be using Windows Vista or Windows 7 in order to function, because they are not available for Windows XP! So why don’t you install the latest video drivers version 186.18 and the 3D Vision drivers included in the package and try the anaglyph 3D mode…

Here is a quick setup guide:
1. Open “Nvidia Control Panel” in Standard or Advanced mode.
2. Select “Stereoscopic 3D” and choose “Set up stereoscopic 3D”.
3. Click on the checkbox called “Enable stereoscopic 3D” in the main panel.
4. A new window will open, where you need to click on the button labeled Next.
5. Put a tick in the checkbox celled “Enable 3D Vision Discover” and click on the Next.
6. You’ll see a message saying no compatible 3D display is found, again click on Next.
7. Now you have to put on your anaglyph glasses and pass the test you’ll be provided with.
8. A new test is being displayed to verify if you are actually seeing depth on a special image.
9. Finally you can see some 3D stereo demo images if everything is fine, but you can as well skip this step.
10. If you’ve passed the two tests everything is ok and you can start playing games in 3D Stereo using your anaglyph glasses.

By default you have set a depth value of 15% which should be Ok for a start, but you’ll probably want to be able to adjust it during gameplay to achieve the best possible perception of depth. If you’ve had GeForce 3D Vision there is a hardware button to easily change the depth percentage, but here you’ll have to do it with a key combination. Another thing that you should know is how to activate and deactivate the anaglyph 3D mode with a key combination, because by default when you run a 3D application it will be automatically activated. If you don’t want that check the Hide stereoscopic 3D effects when game stars in drivers’ control panel. Then when you want the 3D mode turned on you need to just press CTRL + T and then a second time to disable the anaglyph mode so your game will be back to normal. The other useful key combinations are CTRL + F3 to decrease level of depth and CTRL + F4 to increase it, of course there are more kay combinations, but I’ll discuss them later on in a separate topic. This should be just enough to get you started in playing games with anaglyph glasses with a pretty nice 3D effect, although you’ll notice that you have some problems with color reproduction, but that is normal when using anaglyph glasses so don’t worry…

Aside from the color reproduction and perception you might notice one other thing that is also completely normal after using anaglyph glasses so don’t freak out if/when that happens. If you haven’t used anaglyph glasses up until now when you wear them for some time and take them off your vision will be a bit strange for a while. And if you close one of your eyes you’ll either see a hotter image (more reddish) or a colder one (more bluish)… as I told you it is normal and a few minutes later everything will be back to normal. This happens because your eyes adjust with the different color filters the anaglyph glasses use and even when you take them off there is some time needed for them to revert to normal. ;)

Nvidia 3D Vision Discover Glasses

June 21st, 2009 · 10 Comments · Anaglyph Glasses

3d-vision-discover-glasses


Lately there is some talk about Nvidia releasing new 3D glasses called 3D Vision Discover Glasses, but that matter seems to need a bit of clarification. These new 3D glasses are not going to be a replacement for the shutter glasses in the GeForce 3D Vision kit, but something completely different. And although there is already some information or maybe just rumors that Nvidia is preparing a second generation LC-shutter glasses for an update to the existing GeForce 3D Vision the 3D Vision Discover Glasses are not going to do that! Instead Nvidia’s 3D Vision Discover Glasses are going to be a custom-designed, specialized anaglyph (red/blue) glasses that will work with the existing 3D Vision drivers…

With the 3D Vision Discover Glasses, 3D Vision’s drivers and a nVidia-based graphics gard you’ll be able to achieve nice view of 3D Stereo in a lot of games relying on anaglyph technology for depth reproduction. And although the results won’t be as good as with the specialized 3D Vision glasses and a compatible monitor, you’ll still be able to achieve pretty good depth perception on your normal monitor. This means you won’t have to pay for a high-end video card, specialized glasses or even a high refresh rate display, because they are not needed for anaglyph 3D Stereo. Nvidia says it’s 3D Vision Discover glasses will be bundled with selected GeForce graphics cards starting in summer 2009, but there is still not a lot of information about that. You can subscribe to the special newsletter they prepared in order to receive more news when the glasses become available. The thing is that you may already be ready for enjoying 3D Stereo in games if you already own some paper anagyph glasses bought with some 3D DVD movie. Even if you don’t have them you can buy a pair of paper anaglyph glasses very cheap or go for more advanced plastic ones for better results. I personally would recommend anachrome anaglyph glasses as I had best results with them so far, but you are welcome to try any other or just wait for more information from Nvidia…

Either way, I’ll soon be doing some tests with different anaglyph glasses I currently own, until there is more info available for nVidia’s optimized anaglyph glasses, so expect more on the topic very soon… ;)
