[vtk-developers] vtkGeometryFilter and vtkUnstructuredGridBase

[Rostislav Khlebnikov]

Dear VTK developers,

I have come across an issue when using vtkGeometryFilter on an adaptor 
of my dataset which uses vtkUnstructuredGridBase. Apparently, the 
vtkGeometryFilter has not been adapted to use the 
vtkUnstructuredGridBase interface and simply uses a 
static_cast<vtkUnstructuredGrid *> in its UnstructuredGridExecute() 
method. Was this class overlooked during the transition to 
vtkUnstructuredGridBase? For now I can probably use the 
vtkDataSetSurfaceFilter filter as a workaround, but I assume that this 
is a bug and it should probably be fixed at some point.

Thank you,
    Rostislav.
