[vtkusers] Re ading a .vtp

[igorznt]

I use this for reading .vtp files:
        reader = vtk.vtkXMLPolyDataReader()
        path = os.path.join(constant.BASE_DIR, "archive.vtp") #Archive path
        reader.SetFileName(path)
        reader.Update()        
        
        mapper = vtk.vtkPolyDataMapper()
        mapper.SetInput(reader.GetOutput())

        actor = vtk.vtkActor()
        actor.SetMapper(mapper)
