[vtkusers] problems with GetCellNeighbors

[Dominik Szczerba]

Hi,

The following code retrieves cell points, but not cell neighbours, what
is wrong?

  vtkUnstructuredGrid* grid;
  //...
  for(int id=0; id<NCELLS; id++){
	 vtkIdList* points = vtkIdList::New();
	 vtkIdList* cells = vtkIdList::New();
	 grid->GetCellPoints(id,points);
	 grid->GetCellNeighbors(id,points,cells);
	 int np = points->GetNumberOfIds();
	 int nc = cells->GetNumberOfIds();
	 cerr << nc << endl;// always 0
	 points->Delete();
	 cells->Delete();
  }

thanks,
Dominik
