Dear CGAL developers,
I'm trying to mesh a labeled volume of a brain that makes explicit a Sylvian fissure within it, giving each voxel in the latter a large negative value to ensure that the surface surrounding it is captured. The software seems to go into a long, probably infinite, loop that displays "...anifold edges not initialized,non manifold vertices not initialized" in verbose mode.
The last set of values is
(150260,150240,0,25934,non manifold vertices not initialized,) (615.2 vertices/s)
Under what circumstances will an image volume trigger such behaviour? With a simple binary volume that does not emphasize this Sylvian fissure, the meshing converges relatively quickly, but does not seem to identify the surface around the Sylvian fissure.
Best wishes,
Michel
