Re: [ros-users] How to save basic shapes in PCD files

Hi,
I've tried the first option but I haven't been able to get virtual_scanner
package working. About the second option, I don't know well how I can fill
the data of shapes because it could be easy for a cube but not for a sphere.
Could you give me another hint?, please.
