[vtkusers] Points with same coordinates in vtkPolyData

Hi all,

I have a vtkPolyData object that I read from a vrml file using
vtkVRMLImporter. The resulting vtkPolyData contains points and polys, but no
vertexes, lines, or strips.
When I tried to implement an algorithm that should visit all the points in
the object, I found out that several points in the model have different id
but same 3D coordinates. Even after using vtkCleanPolyData, though the
number of points sensibly decreased, many of the points still have the same

Am I missing something trivial here? Why do different points have the same
coordinates? And why there are no vertexes (only points) in my vtkPolyData

Your help is greatly appreciated.
