[vtkusers] vtkPolyDataWriter in vtkpython

[Olumide]

> Apply a vtkTransform filter.

Thanks. I have (see my attempt below -- the transform has no noticeable 
effect). I do not wish to visualize the data. Rather, my intention is to 
have the script write a VTK file.

Is there comprehensive vtkpython tutorial available anywhere? The "VTK 
User's guide" and "Visualization toolkit" are slanted toward the C++ and 
Tcl APIs.

Thanks.
