[vtkusers] dynamically allocate vtkpointer

[128 at gmx.us]

Hi,

How can I create a dynamically allocated vtk pointer. For example,

vtkSmartPointer<vtkUnstructuredGrid> block[3] = vtkSmartPointer<vtkUnstructuredGrid>::New();

can create a size 3 array of vtkUnstructuredGrid pointers. How can I dyncamically allocate this?

Thank you.
