Rviz is a good visualization, but it focuses on a representing the data in a 3d environment. Rviz, in my experience, represents the interactions of the robot (with its sensors) in the environment, you can draw maps and do a lot of things.

However, rviz does not provide access to the data itself. Long history short, while I can see there is an object with the laser scan at a certain distance, I can not see the actual distance of the object. Sometimes we want more info about the data to see what values are best suited to use in our programs.

Wow! And it seems to be relatively fast. Well done!

Very nice, and the simulation actually looks cute :-) Did the laser scan there give you various different scan intervals and that’s why you see the different triangles on the simulation?

Oh, yes that must have been unpleasant :-(

Yes, we are now doing this with ROS (PhaROS) and Gazebo. I never looked at MORSE actually, do you prefer to use it over Gazebo.

Also, are you going to ESUG? We should have a chat...

Ah OK I misunderstood. It could be interesting to do some visualization of sonar scans as well, maybe we will add it to the TODO list.

You can also use bezier lines or SVG ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | v e1 e2 l s p1 p2 path svg| v := RTView new. path := 'M -150 150 Q -75 150 -75 75 Q -75 0 0 0'. svg := RTSVGPath new borderColor: Color red; path: path; element.
