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

Hello friends,
I wonder if it is possible to genarate basic shapes and then save them in a
PCD files. I've seen methods such as pcl_visualization::createSphere or
pcl_visualization::createCylinder, but then I don't know what to do with the
vtkSmartPointer<vtkDataSet> objetc that this methods return.

Could anybody help me? Thank's.
