Hi Adrian, I have had the time to review you submissions yet, but as a general note, in the past I have tentatively planned to use the osg::Shape hierarchy to build a much finer grained segmentation of osg::Geometry - a granularity which is appropriate for ray and other types of intersection testing. This could be done a s KD-Tree.
One needn't use osg::Shape though, perhaps a custom data structure for this type of work might be better. I'd suggest putting it into the core though so that tools like osgUtil::IntersectionVisitor and its associated Intersector classes can all use it. I have also wondered about the possibility of using a custom Registry::ReadFileCallback to automatically generate the intersection data structures. Robert.
