function moveCameraTo(position, duration) {
           var tween =  new TWEEN.Tween( camera.position )
                .to( position, duration )
                .easing(TWEEN.Easing.Linear.None)
                .onUpdate(function () {
                    camera.position = new THREE.Vector3().copy(position)
                    camera.lookAt({x:0,y:0,z:0})
                })
                .onComplete(function () {
                    camera.lookAt({x:0,y:0,z:0})
                })
                .start()
        }

我使用这种方法将相机移动到特定位置，并在开始时正确移动相机。然后TrackballControls不起作用，控制台出现错误。
