[vtkusers] Endpoints of streamlines

[Jan Karel Aaaaaa]

Hello everybody,

I would like to get endpoints and only the endpoints of generated streamlines. I am making an animation of blood flow and I would like to use these endpoints as seeding points for the streamlines in the next frame. However I am new to VTK and I don't have any idea on how to do that... 

Briefly, what I need is a something like vtkStreamline.GetEndPoints().

Can anyone help me with this, please?

Thanks a lot
Tomas
