[vtkusers] how to set point data?

[Petru Pau]

Is there a way to set point data of a vtkPolyData?

The help says:

void vtkFieldData::SetTuple  (  const vtkIdType    i, 
  const float *    tuple
 )  
 Set the tuple value at the ith location. Set operations mean that no range
checking is performed, so they're faster. This method should not be used
if the instance is from a subclass of vtkFieldData  (vtkPointData or 
vtkCellData).
This is because in those cases, the attribute data is stored with the 
other fields and
will cause the method to behave in an unexpected way.

So: how can I modify the vectors that are associated to the points of a
vtkPolyData?
