How to get HTC VIVE Controller’s rotation matrix?

How are you looking to use the matrix? You can get the transform from the OpenVR CHOP. But are you looking to use it in COMPs/SOPs, or do you want the matrix directly to use another way?

Thank you for answer.
I would like to see the result of the transformation of the camera’s projection matrix in real-time, through a change in the real-time matrix of the controller.
