[vtkusers] PolyLine and TubeFilter...

[Vincent Nicolas]

Hi all,

I'm trying to draw some polyline over a polydata surface but sometimes the line pass under the triangles and could not be seen. 
I tried tu use vtkTubeFilter for having a bigger line but it return errors when I pass 2 times by the same polygon. Does anybody has a solution for making the tubefilter working good even with intersections ?? Or maybe an other way to show a polyline over a polydata and be sure it is visible. Maybe colouring triangles ??

Regards,

Vincent Nicolas.
