Hi Joe, There are utilities in osgUtil for building a quad tree from an existing scene graph. Have a look at include/osgUtil/Optimizer it has a whole set of different scene graph optimization visitors, one of them is the osgUtil::Optimizer::SpatializeGroupsVisitor which is written to traverse through the scene graph and find flat groups and automatically subdivides the children into a balanced quad tree.
It might not be exactly what you are looking for, but even if it isn't sufficient as is it will still serve as a good example of how to search for, split and create new group and to move children around. The implementation is found in src/osgUtil/Optimizer.cpp. Robert.
