using hector_trajectory_server to show trajectory in Rviz
I want to show trajectory of the quadcopter simulated in gazebo using Rviz.
I have learned that ‘hector_trajectory_server’ could be used to solve this problem, refer to this old Q&A.
Since i am totally new in this field, anyone could give me some guidance on how to use this node (or Tutorial on using this node)?
Any help will be appreciated. Thanks a lot.
