Hi, there,
 
I would like to display arrows on a closed surface mesh. Given that the the arrows may point inside and outside the surface, I can see the arrows pointing outside the surface using vtkGlyph3D and vtkArrowSource.. However, the arrows pointing inside is not visable. How can I pull out the arrows pointing inside?
 
Is there any function by which I can chang the role between the start point  and end point of an arrow?
or How can I manage to solve the problem? Is there any other way?
 
Thanks a lot!
