[vtkusers] How to import vtk in python?

Hi Lin,

Looks like you may need to modify your PATH environment variable as well as PYTHONPATH. See here:

  http://stackoverflow.com/questions/214852/python-module-dlls

for how to do that on Windows.

> Running vtkPython directly leads python command line with correct vtk module but I'm not very clear about how to run the python test in this way.

You can run "ctest -N -V -R vtkFiltersBezierPython-PatchInterpolation" to see the command line for running the Python test. Note that ctest sets environment variables for the tests it runs but does not list them along with the command line. So running the test with ctest sometimes works when starting things from the command line does not.

They are used to generate source code that makes VTK classes available in python and prepare a python interpreter.
