Hi Ido, indeed the algorithm used in vmtknetworkextraction is the one described in chapter 3. It's a very heuristic algorithm, which is not theoretically guaranteed to preserve the same topology (in terms of Euler number) of the surface and not guaranteed to produce centerlines that lie inside

Hi all, I am trying to understand the the difference between the center-line and network extraction algorithms. I have read the Ph.D thesis of Luca Antiga ( http://www.orobix.com/luca/AntigaPhDThesis.pdf) and understood the details of the center-line algorithm, which is based on a Voronoi diagram
