Re: [wxVTK] wxVTK with python

[Mathieu M. <mat...@gm...>]

Hi Brian,

  I doubt you'll get much help here, as most people here -AFAIK- only
uses the C++ wxVTK. Anyway you did not specify the OS you are running
this (very) short python script into ?

  If this is linux symply run the whole thing via gdb:

$ gdb python
(gdb) run myscript.py

  I would suggest you get rid of the ITK dependencie by either
rewriting your data into something simple (like vtk format), and then
use a simple vtk class to load that data back again.

  If the gdb backtrace is not clear, feel free to send it here.

HTH
