Often I see 'double' when using a larger stereo depth, any tips on removing it? Is there a certain way to watch things that helps? I use Elsa 3D Revelator. | ||

Some basics for better viewing: Adjust your separation - or depth - so that you get no more than about 1/2" (~1 cm) separation between left and right images. Eyes have a hard time fusing the image with more separation. Avoid bright things next to dark things. But, this is hard to do in games. Refresh rate has little effect, if you have a modern monitor. Don't let things come out of the monitor. Do adjust the scene so that things stay inside the monitor. | ||

I believe the word for that problem, from what I have read, is its called "ghosting". I dont bother avoiding seperation, I go for 100% of the 3d effect (about 2.3 inches) that way distant objects look distant and things dont look so flat, but what I do instead is adjust the gamma and brightness and contrast so that things are not so dark. By having about the same brightness for everything, ghosting is hardly noticeable, and where it is noticable it doesnt bother you as much. | ||

I can only go to about 10% without seeing this gosting, so you turn monitor brightness all the way up? | ||

Not the monitor brightness (my monitor only goes so high), but the driver brigtness, and/or gamma settings. And not to give you the wrong idea, it doesnt get rid of ghosting, but makes it less noticable when you are playing the game. If you sit there and analyze the image carefully you will always see ghosting no matter what. | ||

Ghosting is caused by two main reasons - one, the phosphor on the monitor is not fast enough. So, by the time the next image is about to be shown, the phosphor is still glowing a bit with the old image. Two, the ghosting can be caused because the LCD's are not 100% perfect. They can leak a little bit of light. So, some of the left-eye image goes into your right eye. Both of these problems can be improved, as was mentioned, by adjusting the contrast between the colors. This is what can happen when you adjust the gamma. Besides ghosting, another reason for seeing double images is because of too large of a stereo separation. Studies have shown that with a monitor and LCD glasses, most people can only handle a stereo separation on the of up to 20% of the interocular distance - or about 1/2". Thus, if you make the separation too large, your eyes and brain just can't make the image fuse. If someone can go for 100% separation, then they must have great powers of mind over matter. Or, they get headaches quickly. | ||

It may not be so much great powers of mind over matter (I wish  ), but when I look at stereo images I do divergence instead of convergence, and actually when I try to look at an stereo image that requires me to cross my eyes things get blurry for me (hard to focus), but when I look at stereo images that require me to diverge my eyes I can see perfectly fine (kind of scares me when I image myself looking like a lizard with my eyes going diffrent directions :p). It could also be related to the fact that I am near sighted. | ||

The problem is that the focal depth is at a different position that the parallax which doesn't normally happen. The two functions are actually controlled by different parts of the brain and so can be decoupled, especially with training but the result varies from person to person. As the parallax increases so does the difference between the focal distance and the image distance, hence the divergence effect. | ||

1- Set seperation to "1" 2- And adjust depht by increasing convergence. You will see ghosting on close objects(your gun, vs...) rather than distant ones (environment, enemy, target...) Believe me this is more confortable than nvidia's default settings. Besides this is more realistic as everything pops out of the monitor. (You can try to catch close objects and you won't even touch the monitor) | ||

Its not more realistic for things to pop out of the monitor. Realistic is that distant objects look distant. When you look at the mountains in the distance your eyes should be close to parallel. For realism, you need to understand that if the game camera is a foot away from the visible portion of the gun in your characters hand (for an FPS game), if you put your own head a foot away from the monitor, then the gun should almost pixel for pixel the same, and then seperate as it gets farther away. Realism is that most things should sink into the monitor not pop out, think of the monitor as a window to another world, if things are popping out they are really really tiny and really really close to your face (as they pop out of the monitor), if things are pixel for pixel the same, its as if they are being sliced by the monitor surface. There is no real way to maintain realism and not get some ghosting when using shutter glasses. | ||

To eliminate ghosting and monitor refresh-rate limitation problems entirely, has anyone tried doing stereovision the old-fashioned way, i.e. put the two views side by side and use mirrored goggles to overlap them? Of course, this would require two identical monitors to have enough viewing area and a custom set of mirrored goggles. Could the nvidia driver support this? -GianCarlo | ||

Perhaps I should expand on this. By "mirrored goggles", I mean a stereoscope that uses 4 mirrors to combine the views of the two monitors to your eyes. A Prism-type stereoscope could also work also if it doesn't distort the image. I realize I would have to keep my head in a limited space to see the overlap perfectly, but I already do this with my Eye3d Premium glasses. I would also need a video multiplexor to alternate sending the views to the left and right monitors, one after the other. Has anyone tried this? I'm pleased with the eye3D, but I do miss the clarity and contrast I have without them. -GianCarlo | ||

good post. I havent tried it yet, I'll let ya kno. | ||

"mirrored goggles",mirror stereoscopes,it has already been done(e.g. cyberscope some 13 years ago), there are commercial products and if you do some search on the net you will find pages explaining how to build them. | ||

What do you do if you get mirrored images? For example the right side of a cockpit is displayed on the left side and vice versa? So the cockpit is all shrinked together? I have this issue in every game I try 6800 ULTRA and 61.77 have tried FS 2004 and IL 2 FB and Far Cry. The odd thing is that the nVidia test programme works fine??? Where can I post this and get help I have tried several different forums but there don´t seem to be much people using these glasses. | ||

When you start Il2 with default Nvidia settings, it will look like that no matter what. You have to go to the stereo properties and choose IL2Sturmovik (or the game you're playing) and set the hotkeys for increase/decrease Separation (in my case Ctrl+S and Alt+S) and increase/decrease Convergence (Ctrl+C and Alt+C), and Write/Delete settings (Ctrl+W and Alt+W. Once youre set, start the game hit fly and as soon as you're in cockpit hit Pause. Now use your hotkeys to set Separation and Convergence to your comfort. That worked for me ;). CPS_Tenato. | ||

Ah and save them with your Write Config hotkey so the next time you start the game It'll remember them!! Otherwise you'll need to start it all over again! Regards. CPS_Tenato | ||
