static void CopyFieldData(vtkFieldData *target, vtkIdType targetIdx, vtkFieldData *source, vtkIdType sourceIdx)
Copies the fields from the given source to the given target.
static void CopyFieldsWithinRealExtent(int realExtent[6], vtkUniformGrid *ghostedGrid, vtkUniformGrid *strippedGrid)
Given the real-extent w.r.t.
static void BlankCells(vtkOverlappingAMR *amr)
Blank cells in overlapping AMR.
