I just added an example that is closer to what you want...

I have come across some cases where the stripper doesn't produce continuous polylines from input line segments which are continuous - it happens when the line is not closed, and a start segment is chosen from the middle of the polyline, produces a continuous polyline to the end (i.e. no more neigbors), then produces other parts of the polyline as it encounters them in the loop - so what should be a single continuous polyline typically ends up being multiple polylines.  I have a fix for this but haven't had time to check it in yet.  SplineFilter will subdivide the polylines independently.

Look at this example:
http://vtk.org/Wiki/VTK/Examples/ExtractPolyLinesFromPolyData

it shows how to connect the segments produced by the cutter into polylines.

Hello,
I am trying to improve the visualization of sections of surface mesh, so i create a cutter and the apply vtksplinefilter like this;
vtkSplineFilter sf    #sf SetInput planeCut


    sf SetInputConnection [planeCut GetOutputPort]    sf SetNumberOfSubdivisions 6     sf Update   # sf SetLength 0.01vtkTubeFilter rf    rf SetInput [sf GetOutput]


    rf SetRadius 0.1    rf SetNumberOfSides 6
But only i get the initial section with tubes.Any idea?
Pablo
