Things like this don't work: (I've got abnormal termination)
osg::Camera* camera = viewer.getCamera();
osg::PositionAttitudeTransform* xform1 = new
osg::PositionAttitudeTransform();
xform1->setPosition(osg::Vec3(10.,10.,10.));
xform1->addChild(camera);
root->addChild(xform1);
Can someone please write here a code that works?

Hi Robert!
I still don't understand how to do this simple way
so I need thing like this camera-SetPositionAndHPR(pos,HPR);
could you plese write here simple code how to move camera manually to
desired position and rotate it to HPR angles
Thanx in advance
Roman
Why can't you attach the camera node to a PositionAttitudeTransform? Anyway,
you can set your position and HPR angles using a osg::MatrixTransform
instead
of the PAT, I think it's easier here.
