Can somebody explain convergence for me
Im totally new to Stereoscopic 3D and am really confused. Ive searched the boards but no one has posted on this.

How much is the convergence meant to go out, is it just half an inch or so.

Im finding With even an inch or 2 the 3D effects barely come out of the screen.

check out the stereoscopic settings guide on this website www.mtbs3d.com (under the guides tab)

It's a great guide with videos included for good measure

I like this explanation from another post:

"
Lets say you had a piece of glass in front of you. If that glass represents your 3d gameview, then Convergence controls how far away that glass appears to you (holding it closer or further) and Separation controls how thick the glass is.

Expanding this to a shoebox diarama analogy, Convergence controls how far the diarama is from your face and Separation controls how deep the shoebox is. Separation controls can be used to stretch the box so it's very deep or compress the box until it's 2d.
"

Increasing convergence brings things closer to you so you might want to remap the hotkeys to help you remember it. You can set inc-conv to keypad-3 and dec-conv to keypad-9. The 3 is closer to you so use it to bring things closer.

"How much is the convergence meant to go out?"
It depends on the game and your personal preference. That's why there's no one answer. A good starting point for a 3rd person shooter is to converge on your character with your glasses off, then adjust separation to taste and tweak convergence again from there. Another standard is to base your settings on your game's aiming reticle if you're depending on that alot. If your reticle is 2d, then you need to converge on something that you might aim at at medium range and then adjust sep from there.

check out the stereo images from the KOTOR thread to see the difference the right convergence setting can make with regard to a 2D HUD and 2D text labels of distant objects.

"3D effects barely come out of the screen"
Don't get hung up on things coming out at you. It can be too much and feel/look bad with your eyes crossed too much. Think of it more like a window. The world is 3d outside but you don't have things poking you in the face through the glass. Still, if you're like me, there will be some games that you get to like with alot of popout.

I think that's it.
have fun.

Also take a look at this presentation, it contains a lot of useful information: [url="http://developer.download.nvidia.com/presentations/2009/SIGGRAPH/3DVision_Develop_Design_Play_in_3D_Stereo.pdf"]3DVision_Develop_Design_Play_in_3D_Stereo.pdf[/url] ;)
