    Thanks for clearing that up, Dave.<br>

    I will take a look at the filters that I need and share my changes

              VTK developers,<br>
              <br>
              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<br>

            <div>At this point, there are a lot of filters that won't
              work with the vtkUnstructuredGridBase and
              vtkMappedDataArray interfaces. These are newer,
              experimental features that are currently only used in a
              handful of applications. If you end up needing to adapt
              any filters, etc to use them, consider sharing the
              modifications on gitlab so we can improve support.</div>
