Your environment

  • OS Version: Ubuntu 20.04
  • ROS Distro: Noetic

Sorry, but I don't understand your question. Obviously, you are able to display your point cloud.
What else are you missing? You can't save data from rviz. If you want to record data, consider rosbag.

What I want is for a map to be generated with the points that the rviz shows me, as with RTABMAP, but the problem is that a map is not generated from those point clouds

rhaschke commented

I don't know about RTABMAP. In any case, rviz doesn't perform any processing, it just displays information available in your ROS system. So, if you need to process the point cloud into some map, this should be handled elsewhere.
