[vtkusers] How to generate streamlines on surfaces?

[Petru Pau]

This is a more specific question about generating streamlines on surface.

The VTK help has the following sentence, regarding vtkStreamer:

"vtkStreamer integrates through any type of dataset. As a result, if the 
dataset contains
2D cells such as polygons or triangles, the integration is constrained 
to lie on the surface
defined by the 2D cells."

Well, the example that produced the image from my previous mail consists
entirely of triangles; however the integration is not restricted to the 
surfaces
of those triangles.

Why?
