三JS：如何克服万向节锁定

Question

我试图在按钮单击中将摄像机移至左，右，上，下，前和顶视图，在此我捕获了该轴并将其设置为摄像机位置，在此我获得了云台锁定旋转不起作用的地方。而尝试旋转我放大的相机的对象时。我的代码做错了什么？

public testViews() {

    const that = this;
    let axisHelper;
    let distance;
    axisHelper = new Vector3(0, 0, 1);
    that.cameraHandler.cameraProperties.eye.copy(axisHelper);
    that.camera.lookAt(that.cameraHandler.cameraProperties.center.clone());
    that.cameraHandler.cameraProperties.eye = that.cameraHandler.cameraProperties.center.clone();
    return;
}
