Where's setTetherNode in osgEarth2.10？

[MRdesperado1]

Hello, I found no setTetherNode function when using osgEarth2.10. What should I do to bind a node?
How can I bind the viewpoint to the aircraft model so that the viewpoint and the model move at the same time?
I use OSG version 3.6.3 and osgearth version 2.10.
In addition, when I try to paste an airport model on my osgearth, my airport model is always suspended, even if I set the altitude to 0.

The code is as follows：

   csn = new osg::CoordinateSystemNode;
csn->setEllipsoidModel(new osg::EllipsoidModel);
airport = osgDB::readNodeFile("E:/OSG/Data/model/airport.ive" );
mtAirport = new osg::MatrixTransform;
/*mtAirport->getOrCreateStateSet()->setMode(GL_RESCALE_NORMAL, osg::StateAttribute::ON);*/
mtAirport->getOrCreateStateSet()->setMode(GL_LIGHTING, osg::StateAttribute::OFF | osg::StateAttribute::OVERRIDE);
mtAirport->addChild(airport);
mRoot->addChild(mtAirport);

osg::Matrixd mtTemp;
csn->getEllipsoidModel()->computeLocalToWorldTransformFromLatLongHeight(osg::DegreesToRadians(34.3762), osg::DegreesToRadians(109.1263), 0,mtTemp);
mtAirport->setMatrix(mtTemp);

Thank you very much!!!

To lock the camera on a node, create an osgEarth::Viewpoint and call setNode. Then call EarthManipulator::setViewpoint to apply the viewpoint.

Thank you very much. I still want to ask you. My airport displays floating in the air. As the viewpoint moves, the airport will also move. How should this situation be solved?
Thanks again.
