.vtk is a legacy format. You should have instead used a
vtkXMLPolyDataWriter to save it to a vtp file.

If it is saved in a vtk file as vtkPolyData, there should be no need
to convert anything, just to read it appropriately. You can't use
vtkXMLPolyDataReader (unless you correct your first step and use
vtkXMLPolyDataWriter) - you'd have to use vtkPolyDataReader (which
there is no example of, but from the documentation it sounds like it
should just work) , or something like this:

What is wrong? What are the errors? etc.
