<p>Thanks, once again.</p>
<p>After hours* poring through the SlicerRT source I finally found
something useful. For anyone else who comes up against this
problem here are some useful links to a solution:</p>

the DICOM-RT importer in 3D Slicer’s SlicerRT extension
(<a class="moz-txt-link-abbreviated" href="http://www.slicerrt.org">www.slicerrt.org</a>). It manages branching, smooth
end-capping, etc. If it works for you then you can either
use it as is or just have a look at the source code and use
it in your own software (the planar contour to closed
surface converter only requires VTK).</span><span

<p>Hi VTK Users,</p>
<p>I'm currently using vtkRuledSurfaceFilter to convert a
sequence of contours into a surface. The problem is that if
two contours happen to be on the same plane the surface filter
will join them resulting in artefacts.
<br>
</p>
<p>Any suggestions on how to deal with this?</p>
