<p class=MsoNormal><span lang=EN-GB>I am not really familiar with how curves
and surfaces are typically represented in ITK. I found PolyLineParametricPath as
an example, but that is only for two dimensions (see: <a
href="http://www.itk.org/Wiki/ITK/Examples/Curves/PolyLineParametricPath">http://www.itk.org/Wiki/ITK/Examples/Curves/PolyLineParametricPath</a>).
I would like to have a representation which is easily scalable to 3D. In
practice this surface does not necessarily have to be a closed surface.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-GB>For example, what would be the best way to
proceed for the following simple operations, given an initial contour (let’s
say in 2D):<o:p></o:p></span></p>
