Just got the Eye3D Premium, very satisfied with the shipping.

I've setup everything, it's simple, I also use detonator 45.23 and stereo 45.23. The glasses can be activated, it works in the medical test. Well basically it works, I can change the presentation of the 3D, etc

But I was expecting the 3D effects like the ones I watch in IMAX, that the pictures are 'coming out' from the screen.

What I see is the 3D is working but the image is not one bit looks like coming out from the screen, the image is still inside the monitor. I've tried this with game Soldier of Fortune 2 and Max Payne 2. SOF2 should be one of the best game using 3d shutter glasses from what I read.

So should the pictures actually floating outside the monitor or is it just giving the feeling of 3D perspective only?

I'm not a gamer, but I would think that your "Separation" settings in your "Advanced Stereo Properties" will enable to to make things "pop out" at you (in front of the stereo window).
Go to "Properties" > "Settings" > "Advanced" > "GeForce FX 5600" (or your video card)
> "Stereo Properties" > "Advanced Stereo Properties".
Here's a screenshot:

In the "Separation" section, set your hotkeys for something that you aren't already using in the game, start the game, then use those hotkeys to shift the images "forward or back" in the scene.
Let me know if that works :-)

Hi mysrh,

But I was expecting the 3D effects like the ones I watch in IMAX, that the pictures are 'coming out' from the screen.

There is nothing wrong with your glass (at least not based on what you are describing).

Whether the 3d objects are "out" or "in" depends on a few factors. Such as the program itself. Back in the early days of 3d gaming, a few (very few) programs were written specifically for stereoscopic 3d, such as Descent I and II. There, the objects were both in and out, truly spectacular effects. These days the typical games are not written for stereoscopic 3d, but the technology allows to see it that way anyway, but the programmers don't think of placing objects outside of the screen. However, you can still achieve the effect, by simply using your hotkeys related to the stereo 3d effect.

I am not using detonator 45.23 and stereo 45.23, I still use some older version, but it should work similarly. In my case:

Display properties
Settings
Advanced
Stereo Properties
Game Configurations
Configure Hot Keys

and there you will find:
Increase Convergence
Decrease Convergence

On my computer, I don't remember whether this was the default or I changed it, doesn't matter, look up the two hot keys. You may want to jot down the rest of the hotkeys (I did until I learned them).

Then get out of there and go to the game. Activate 3d.
Now, find a situation in the game, where some of the objects "should be outside", but they are not.
Now play with the convergence, until the desired "out" and "in" achieved.

Ps: I just see Chris to come around and give me a lecture that this is not how to do it, and besides he doesn't like "objects out", but I do, and this is how I am doing it.

Chris is not the only one who doesn't like "objects "too much or completely" out".(like in the pub brochures)
It is one off the worst situation in respect off eyes strain and ghosting .

From physiologic reason the out of screen effect is accptable when you are in a enought big distance from the projection screen (e.g. in IMAX).
But even in IMAX the big out of screen effect is mostly a non-wanted bug produce by the IMAX camera recording system non-ability to be in optimal ditance (to big camera - imposible to achive low camera separation). You should watch the latest IMAX movie - complately CG generated Cyberworld 3D. The first IMAX movie with perfect stereoscopic gometry ...

Another situation is PC screen - hi out of screen efffect accptable for projection simply must produce disconfort.

Just to echo what was said and to add a comment or two, it can be irritating to watch 3D with objects popping out in front of the screen unless the scene was specifically created for this effect. This makes it impossible to properly adjust on-the-fly without going back to the original source and changing it.
What technically happens is when those objects touch the sides (top, bottom, left or right edges) you get what is called a "stereo window violation" where only part of an object can be seen with one eye when it happens on the sides, or the object appears to be appearing from "no where" when it happens at the top or bottom, which since that doesn't happen in reality, it never looks *natural*, especially on a small monitor or projection screen.
I only recently fully understood the top and bottom "window violation" theory, which has been the topic over in the Yahoo Photo3D group this past week or two.

We where talking about stereo effect on a computer screen (viewing distance +or- 60cm)

Very appreciate with the input =)

Is it true that convergence and depth level hotkeys only applicable in the specific game configuration? Some of the won't recognise the hotkeys despite the NVIDIA says it can.

I've tried to play with the convergence but it did nothing but separating the image, and both the convergence and separation is like cancelling each other.

The level of depth isn't doing anything too

Hi mysrh,

Yes, I found that in some programs the convergence is not recognized, but the separation always seems to work.

I've tried to play with the convergence but it did nothing but separating the image, and both the convergence and separation is like cancelling each other.

Not really, although if you are not experienced, it may appear that way (of course, if you decrease the separation, whatever effect of convergence may had, will be decreased). The separation sets the "overall 3d-ness", so to speak. The convergence appears to control the "in-out" position of the objects. Of course, you have to use that reasonably. An object would have to be "near the screen surface" in the first place, to bring it outside of the screen. Try it with some driving game, and pay attention to the road which is nearest to you. Try to touch the imaginary beginnning point (nearest to you). Now change the convergence. Pay attention to the road divider (for example). If without glass it exactly runs into one point, that's when it should be exactly on the screen surface (not in, not out). From this position go one way, then the other way with the convergence. And while testing all these, leave separation alone.

Opposed to some others, I like the "out of screen" effect somewhat, but only in certain programs. Like in driving games I do bring the road a "little out", increases the speed sensation (and the road never comes to the screen edge which can mess up the effect). I used to love Descent 1 and 2, where several of the "found objects", if went near enough to them, came out of the screen, making the 3d effect look really spectacular, but that was different, it was made for 3d. Oh well....keep one experimenting, that's what is 3d all about at this point (:-).

Or if you cleverly choose programs which are immune to this problem, see driving games, "first person perspective" where the beginning of the road is always in the middle of the screen. Try it, you will be surprized how nice the effect is.
