Shahmi,

You probably won't need to write any nodes. To visualize your data, you will need a node to communicate with the laser driver and publish the scans, and then rviz to visualize them. If your laser is a Hokuyo or a SICK, there is support for them in the laser_drivers stack:

Do you have a node publishing the cloud point?

To run rviz, you just need to run:
> rosrun rviz rviz

You should have a look at: http://www.ros.org/wiki/rviz/UserGuide

Hi all,

I would like know, do we need to write a node in order to run RVIZ package. I actually want to visualize data  from laser scanner via RVIZ. Is it possible to run it even without any node written.

Thanks in advance.

Regards,
Shahmi
