Thanks for the reading obj example, Pat. I looked at dir(vtkio) after
importing it, and it looks like there is an ObjReader, but not an ObjWriter
(makes sense, because I've been wondering the same thing about the missing
objwriter in c++ vtk). How do people generally write obj files from
polydata's?

Thanks,

David
