CGAL users discussion list

Dear CGAL developers, 

I saw that the CGAL code has C3T3 and C2T3 to VTK converters, but I was wondering if the reverse converter exists somewhere. I am using MINC-formatted segmented volumes as input, which VTK can process but CGAL cannot. Moreover, these volumes have thin cracks (one or more sulci that I want to account for) that apparently gave problems to the CGAL polyhedral surface extraction (which I attempted after a conversion from MINC to Analyze), so I'm trying vtkMarchingCubes first, then would like to attempt the edge-collapse decimation,  and compare with VTK decimation methods. I need to either convert from a vtk surface output to CGAL C2T3, or use the vtkPolyData info to construct a CGAL polyhedral surface. Is there an example somewhere that I can use to achieve this? 

Best wishes, 

Michel
