Normally, Modified() is automatically called on a VTK filter when its<br>
Set methods are called, but for the vtkProgrammableFilter it is<br>
necessary to can Modified manually.<br>
<br>
Also, generally you should let the VTK pipeline execute the filter<br>
(which it will do when Render is called), instead of calling Update<br>
manually.<br>
