Setting camera from 3D scanner

Hi

I'm trying to set the camera of Moi to have the same position and orientation as the one I have with a 3D scanner.
The 3D scanner gives me R and T for a camera. (Each point is transformed as R * P + T).

I know the position of the camera which is given by Xc = -tranpose(R) * T
The viewing direction is given by the third row and the up vector is given by the second row.
How can set them in Moi ?
