This is not a simple topic to reply to and I dont have the time to say
too much but you might want to read this thread:

Essentially you can use the functions inside vtkPythonUtil.h to
convert from/to Python and C++.  As I said I haven't really thought
about your problem enough to say that the above will be enough but I
hope you should be able to figure it out.
