Hi everyone,<br><br>Just a follow up on the thread from a couple of days back:<br><br><a href="http://public.kitware.com/pipermail/vtkusers/2006-October/087856.html">http://public.kitware.com/pipermail/vtkusers/2006-October/087856.html
</a><br><br>What I am doing is basically just selecting points on the image and running a spline through it. In the end, the loop is closed and the 2d surface is extracted using vtkImageStencil.<br><br>Now, the points basically are randonly selected and can change direction with successive points. The resulting surface also can either be concave or convex. I am very confused as to what determines the orderness of points (clockwise or anti clockise?) as the surface can grow in either direction...
<br><br>Cheers,<br><br>Anja
