VTK type converter.
This module handles conversion between VTK C++ and VTK Python objects so that one can write inline C++ code to manipulate VTK Python objects. It requires that you have VTK and the VTK-Python wrappers installed. It has been tested with VTK 4.0 and above. The code is based on wx_spec.py. You will need to call inline with include_dirs, library_dirs and often even libraries appropriately set for this to work without errors. Sometimes you might need to include additional headers.
