vtkCellArray * Cells
Storage for cells of output unstructured mesh.
bool IsPlaneOrthogonalToZAxis()
Returns true if plane's normal is aligned with the corresponding axis, false elsewise.
vtkBitArray * SelectedCells
Storage for pre-selected cells to be processed in dual mode.
virtual void Reset()
Resets every attributes to a minimal state needed for the algorithm to execute.
vtkCutter * Cutter
Cutter to be used on dual cells.
