Hi Shahmi,

I haven't used this in more than a year, but I believe laser_view will do what you're looking for.  It displays a 2D plot in Cartesian space of the laser data:
https://sail-ros-pkg.svn.sourceforge.net/svnroot/sail-ros-pkg/trunk/semistable/visualization/laser_view/
Maybe someone else knows if this code is still does what I think it does.

Also, if you want to write the viewer yourself, you could simply do the conversion to Cartesian coordinates using the laser_geometry package:

Shahmi,

Take a look at the pr2_tilt_laser_interface action (LaserScan->PointCloud2) or the older laser_assembler
(LaserScan->PointCloud) for an example.

For visualizations, you can use rviz or pcd_viewer in pcl_visualization (for individual snapshots).

Cheers,
Radu.
