Hello-
I might be missing something obvious, but I can't find any helper functions for converting a rotation matrix to a quaternion.
I made a rotation matrix by choosing 3 basis vectors and putting them into a btMatrix3x3 (or equivalently, a tf::Transform with 0 position offset).
I would like to just be able to just make a quaternion from this matrix. Does tf really not have a helper function for this? All I find are "createQuaternionFromRPY" sorts of functions, and Quaternion itself does not have a constructor that accepts a rotation matrix.
Thanks,
Adam
