VtkHyperTreeGrid Super cursor issue in python

Development
1

Hello,

I notice a bug with the vtkHyperTreeGridNonOrientedMooreSuperCursor (and Von Neumann) using the Python interface. I am trying to get the cursor at neighbours of a specific cell but the call to the “GetNonOrientedGeometryCursor” (same issue with “Oriented”) function on super cursor leads to an error.

This is the problematic function call :

cursor.GetNonOrientedGeometryCursor(SOUTH)

Which leads to the this error :

ValueError: cannot create object of unknown type “vtkSmartPointer_I41vtkHyperTreeGridNonOrientedGeometryCursorE”

I am using the vtk-9.0.1 installed with pip.

Thanks for your help;
