I am trying to get a thin, colored border line - color coded to indicate axial, sagittal, and coronal - on the edge of 3 typical orthogonal cut planes through an image volume. It looks like I can possibly use vtkCutter() like in the example here: [https://vtk.org/Wiki/VTK/Examples/Python/vtkCutter](https://vtk.org/Wiki/VTK/Examples/Python/vtkCutter). However, before I tried that, I was wondering if BorderOn() might do the trick? I have not been able to find much documentation on BorderOff() / BorderOn() and was wondering if somebody could point me in the right direction?

Thanks in advance.
