i have two viewers and put the scene in groups one for the whole scene and one 
for the pointer i want to move:

osg::Group* root = new osg::Group; // groupp have all other objects
        osg::Group* Mainroot = new osg::Group; // the whole scene
        Mainroot->addChild(root);

osgViewer::Viewer viewer;
osgViewer::Viewer viewer1;

//set left camera for left view
osg::ref_ptr<osg::Camera> cameraL = new osg::Camera;
...
// add the matrix transformation 
osg::MatrixTransform* mt = new osg::MatrixTransform;
                mt->setMatrix( cameraL->getViewMatrix() );
                mt->addChild( loadedMode35 );
                Mainroot->addChild(mt);

viewer.setCameraManipulator( keyswitchManipulatorL.get() );

//set right camera for the right view
osg::ref_ptr<osg::Camera> cameraR = new osg::Camera;

viewer1.setCameraManipulator( keyswitchManipulatorR.get() );



//load data for each viewer
viewer.setSceneData( root);
viewer1.setSceneData( Mainroot);


//run the viewer
while( !viewer.done() )
    {
        // fire off the cull and draw traversals of the scene.
        viewer.frame();
        viewer1.frame();
        
    }

now the object i used did not move what is the problem ??
