LineSegmentIntersector::Intersection has a member: matrix which is the accumulated local to world coordinates matrix. If you transform the nodes BoundingSphere center by that, you can then construct an aabb around that at whatever size you want. -- http://www.ssTk.co.uk _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
