This seems to be a very common question (around my university as well as on the mailing list). Joel, maybe once you get it working you can post the procedure/code on the examples wiki (<a href="http://www.vtk.org/Wiki/VTK">http://www.vtk.org/Wiki/VTK</a>)? Or send me the code/sample data set and I can try to clean/comment it for posting.<br>

Hi Joel,<br>
<br>
I guess you want to run an inside/outside test with the polylines. I would suggest you have look at this post:<br>

Hi all,<br>
<br>
I'm trying to create a 3D surface mesh from a stack of 2D contours created<br>
from a semi-manual contouring platform I have no control on. For now I have<br>
succesfully converted the contours to vtk polylines. My idea is to binarize<br>
the the polylines, and to run a marching cubes on the resulting binary<br>
volume.<br>
<br>
Unfortunately, vtkPolyDataToImageStencil doesn't work for polylines. So<br>
before I start coding a polyline binarizer, would anyone have a better idea,<br>
or such a binarizer in stock? (the code will be integrated into the<br>
open-source 4D viewer vv)<br>
<br>
Thanks,<br>
<br>
