no .
i chang this code form sample code to load ground plane
plane = Loader.load3DS(res.openRawResource(R.raw.plane01),100);
and make the camera flollow tank object by equation x = a+r*sin(angle of boject) : y = b+r*cos(angle of object)
cam.setPosition((float)(tankh.getTransformedCenter().x+150*Math.sin(((touchTurnA+1)/360*2*Math.PI)-Math.PI/180*5)), tankh.getTransformedCenter().y-50,
(float)(tankh.getTransformedCenter().z+150*Math.cos((((touchTurnA+1)/360)*2*Math.PI)-Math.PI/180*5)));
cam.lookAt(tankh.getTransformedCenter());
