Hi ?? I have tested the osgwidget examples they fail for me when running in stereo. I'm not the author of osgWidget so can't comment too much on the internals, but the design is very much for 2D HUD style GUI's that overlay the scene, I have looked at generalizing it but couldn't find an easy way to do this as various parts of it's design assume 2D GUI.
I am currently working on project that needs GUI elements do be placed into a stereo scene and to achieve this am writing a new GUI NodeKit called osgUI. The osgUI library isn't ready for use, but it does work fully in a 3D scene or as a HUD, and both the graphics and event handling all work in the 3D scene and in stereo - I've just tested in anaglyphic and horizontal split and it all works fine. I plan to keep the osgUI library pretty simple but make sure it's very flexible to allow users to extend/customize it as required - it also fully supports scripting. osgUI not a direct replacement for osgWidget but overlaps enough that it will deprecated it. For OSG-3.4 I'll keep likely keep osgWidget for backwards in compatibility, but beyond this I'm thinking about annexing it into an dedicated osgWidget project so it can be maintained separately from the core OSG.
