I'm trying to display the skeleton that the openni_tracker detects in rviz. I just installed pi_tracker and ran the skeleton_tracker node that uses it's own program for visualisation, but I know you can track the skeleton in rviz.
The TF display in rviz should be ok, it reports that it successfully found all the /tf-s used for different body parts, but now I don't know how to represent them and visualise them with markers, but I can't find any published topics with the message type that the Marker needs.
First thing I'd like to ask is: do I need another node or something that could publish the topics readable by the Marker?
Second: Do I need to use a Marker display type or something else, like MarkerArray instead?
