Great! This is perfect. In case anyone else is wondering, a 2D double
array can be created/used as follows:

vtkSmartPointer<vtkDenseArray<double> > array =
vtkSmartPointer<vtkDenseArray<double> >::New();
array->Resize(5,5);
array->SetValue(4,4, 5.0);
vtkstd::cout << array->GetValue(4,4) << vtkstd::endl;

Thanks,
