Parameters Three.JS CombinedCamera调用预定义参数

我正在为Three.JS场景使用组合摄影机库，并希望在切换时为每个模式设置（重置）预定义参数

function changeCameraMode(mode_){

    var s = "first person";
    if(mode_) { s = "birds view"; } 

    //false: first view, true: bird's eye
    console.log("mode: " + s);

    if(mode_) { camera.toOrthographic(); 

    camera.cameraO.position = cameraSettings.orpho.position;
    camera.cameraO.rotation.onChangeCallback._x = cameraSettings.orpho.rotation.x;
    camera.cameraO.rotation.onChangeCallback._y = cameraSettings.orpho.rotation.y;
    camera.cameraO.rotation.onChangeCallback._z = cameraSettings.orpho.rotation.z;

    camera.cameraO.top = cameraSettings.orpho.top;
    camera.cameraO.left = cameraSettings.orpho.left;
    camera.cameraO.bottom = cameraSettings.orpho.bottom;
    camera.cameraO.right = cameraSettings.orpho.right;

    camera.quaternion._x = 0.17446644315139806; 
    camera.quaternion._y = 0.40250876457862955;
    camera.quaternion._z = 0.07844478023909554;
    camera.quaternion._w = 0.8952064404955571;

    camera.rotation.x = cameraSettings.orpho.rotation.x;
    camera.rotation.y = cameraSettings.orpho.rotation.y;
    camera.rotation.z = cameraSettings.orpho.rotation.z;

    camera.position = cameraSettings.orpho.position;

    camera.updateProjectionMatrix();

    } 

    else { camera.toPerspective(); }

}

我已经使用了几乎所有的变量（见上文），但实际上什么都没有发生。

有什么想法吗？

我在FirstPersonControl.js中使用过它，实际上我要做的是：

controls.lat = value0_;  
controls.lon =  value1_; 
controls.phi =  value2_;
controls.theta =  value3_;

camera.lookAt(controls.target);
