如何旋转屏幕中心

Question

旋转屏幕时，就像搅拌机一样，我想将屏幕旋转到屏幕中心的一个点。 但是，由于屏幕中心，是一个2d坐标，所以即使屏幕中心向量出来了，对应的点也没有出来。 即使有一个向量，相机在直线上拍摄，该点也无法准确知道，所以我不知道旋转屏幕的中心点zpos。

我不知道如何指定屏幕中心坐标的 z 轴，以便它像搅拌机一样穿过屏幕中心。 网格图块是否基于 z 轴？

void setRotInsideOtherWay(Vector3 ve3)
    {
        Debug.Log(CameraManager.S.LookPos);
        //1 this way is not work
        //2 Lookpos is tranform.foward
        //mCamParent.transform.Rotate(ve3);
        //mCamParent.transform.LookAt(CameraManager.S.LookPos);

        //
        Camera.main.transform.RotateAround(point , ve3,10f);
      

    }
