    I was wondering if anyone found a workaround about the Undistort functions in the camera defaults and Input Cameras panels.

    What’s the difference between Undistort a, b and c? And what about K1, K2 and R? For the moment I just tweak them until I like what I see, but I’d like to know what’s the real meaning of these values.

    Any idea?
