[vtk-developers] Do I need to delete an object when I create a smart pointer of it?

I am always prudent when using VTK, i. e. I never mix the smart pointer and
normal pointer of VTK objects.

I have a concern. Suppose we have

vtkPolyData *mesh = some_function_which_returns_vtkPolyData_star(...);
vtkSmartPointer<vtkPolyData> mesh_ptr = vtkSmartPointer<vtkPolyData>(mesh);

we should do mesh_ptr->Delete() after, right?

However, can we do

vtkSmartPointer<vtkPolyData> mesh_ptr =


If we do that, how can we delete the reference count to the object before
passing it to vtkSmartPointer?
