[vtkusers] Writing VTK filters in Python and C

[David Gobbi]

To add some additional clarification,

1) It isn't possible to write a VTK filter in Python.  Maybe sometime
   in the future it will be.

   Well, that's not quite true... if you look into all places where you
   can hook callbacks into VTK it probably is possible in some limited
   cases.  But it wouldn't be easy, and I wouldn't advise it.

2) Writing & wrapping your own VTK classes is a topic that is covered
   fairly substantially in both the User's Guide and in the archives.
   In VTK 3.x it basically amounts to adding your class to the appropriate
   VTK subdirectory (usually 'local') and adding the class name to
   the Makefile.in in that directory, then running 'configure'
   (or pcmaker), then make (or nmake).  For VTK 4.x this topic was
   recently discussed to death, and I can't tell you my method because
   the VTK gods have declared it to be heresy ;)
