Is there a build-in tf2 functionality where we can generate a rotation matrix given an axis (tf2::Vector3) and an angle (double). E.g. Suppose you have:

tf2::Vector3 vec(2,3,4); // by axis I mean - any - axis, not just x,y,z
double angle_rads=1.57;
tf2::Matrix3x3 rotation_matrix(vec,rads); // <-- is there an easy way like this?

OK found it my self :) For people that are wondering (it goes through Quaternions):

tf2::Quaternion q;
tf2::Matrix3x3 R(q);
