You both may want to take a look at osgIntersect for both box selection and the selection of lines and points. Let me know if you have any questions as I'm highly familiar with the code base.

I also don't mind cleaning up the code, which may not even be necessary in my case since we also use MFC-reminiscent naming conventions. Actually, I was also planning on using this method for single selection since using the osg::IntersectVisitor it is nearly impossible to select a line or a point.
