If I do this, then I need to maintain the underlying ref_ptr object no? This isn't particularly convenient. What was wrong with assigning the osg::Node's pointer to mysteryPtr instead? Basically with ... osg::ref_ptr<osg::Node> someNode; mysteryPtr = someNode.Get(); As long as the pointer returned by the Get() method is valid for the lifetime of the object I'm safe right? Then if I want to do anything with object: osg::ref_ptr<osg::Node> someNode = some_cast_call<osg::Node*>(mysteryPtr); someNode->partyAllDay(); > > Code: > ref_ptr< Node> &node = *reinterpret_cast< ref_ptr< Node> *>(mysteryPtr); > > > > And don't forget to delete the pointer to the ref_ptr<> when you're done. if > you leak the ref_ptr<> the node will never get collected. > > ------------------ > Read this topic online here: > http://forum.openscenegraph.org/viewtopic.php?p=46372#46372 > > > > > > _______________________________________________ > osg-users mailing list > osg-users@lists.openscenegraph.org > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
