I'm not sure I understand your issue. If you can pick one quad, then you should be able to pick several. Are you unsure of the user interface you should implement? Or are you unsure of how you should track the picked primitives? More info please.

During user interaction, I need to pick ( using a selection rectangle) a significant subset ( say 10K) of these primitives and "highlight" them ( simply turning the picked primitives wireframe would do). Any suggestions on how to do this efficiently? I have OSG picking working great with osg::Node objects but am a bit unsure of how to pick a subset of primitive QUADS/TRIS from a single geometry. Thank you!
