Hi,
GetCell(...) is intended for internal use (see the doxygen
documentation) where loc is not the cell id, but an offset in the
internal array. Using InitTraversal together with GetNextCell instead
would be easier.

Hello,
I have been reading and reading this piece of code but cannot figure
out what is wrong!
I create a couple of cells of 4 ids and get...anything but what is
expected.
Please tell me where I am wrong!
vtkCellArray *faces = vtkCellArray::New();
vtkIdList *fIds = vtkIdList::New();
for (int i=0 ; i<faceIds.size() ; i++) {
for (int j=0 ; j<faceIds[i].size() ; j++)
fIds->InsertNextId(faceIds[i][j]);
faces->InsertNextCell(fIds);
printf("cell %d has %d ids\n", i, fIds->GetNumberOfIds());
fIds->Reset();
}
for (int i=0 ; i<faces->GetNumberOfCells() ; i++) {
vtkIdList *list = vtkIdList::New();
faces->GetCell(i, list);
printf("cell %d has %d ids\n", i, list->GetNumberOfIds());
}
