<DIV></DIV>>Subject: [vtkusers] using vtkClipPolyData, It triangulate polygons.

<DIV></DIV>>
<DIV></DIV>>Hello,
<DIV></DIV>>
<DIV></DIV>>I have some polygons. I am interesting in the coutour/border
<DIV></DIV>>of them only.
<DIV></DIV>>
<DIV></DIV>>Everything is in a polydata (points and polygons). When I try
<DIV></DIV>>to clip this polydata with a volume, all my polygons are
<DIV></DIV>>triangulated.
<DIV></DIV>>
<DIV></DIV>>1. How to get my polygons clipped only as polylines ?
<DIV></DIV>>2. should I create polylines instead, will it create some links between broken lines parts ?
<DIV></DIV>>3. Is there a way to get contours of my polygons back in the
<DIV></DIV>>polydata ?
<DIV></DIV>>
<DIV></DIV>>Sebastien MARAUX
