Hi Sergey, It really is very hard to locate the code portion where it implements the rubber drawing, I'm paving my way with osgHUD example to create the rubber banding.

For selection part OSG Beginners book suggest to use osgUtil::PolytopeIntersector for regional selection, but doesn't give any clue on how to draw the rubber or is it comes as an intrinsic feature of sgUtil::PolytopeIntersector when you create it with WINDOW parameter set on. I also studied the osgkeyboardmouse.cpp example, but I couldn't find any visible difference when I switch from LineSegmentInteresect to PolytopeIntersector, while I was expecting to see the HUD window rubber to be drawn and objects falling into that rectangle to be selected. Your guidance will be appreciated!
