Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. * \param out The Pose converted to a tf2 Transform type. * This function is a specialization of the fromMsg template defined in tf2/convert.h. So, if you manage to use this interface, then its all plug and play. * \param t_in The point to transform, as a Point3 message. To learn more, see our tips on writing great answers.
