On the nodes in your scenegraph, use osg::Node::setNodeMask() to define their masks. When doing collisions, use osgUtil::IntersectionVisitor::setTraversalMask() If the bitwise AND of both masks is true, a collision will be attempted. Be careful to not set a more restrictive mask higher in the scenegraph than the mask on some lower node. -- Terry Welsh www.reallyslick.com _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
