Dear CGAL users,

I have begun playing with edge_collapse() surface mesh simplification,
and I'm trying to reduce a brain surface to its barest essence while
still remaining close to the boundary as possible. This is from a
binary volume where I have obliterated all but one sulcal fold (the
left Sylvian fissure).

I would like to play with various policy options for this surface mesh
simplification, to better preserve the faithfulness of the simplified
surface to that fissure. Are there examples for doing that, e.g. for
penalizing the deletion of an edge shared by two faces at a large
angle to each other, assuming that the faces were faithful to the
tissue boundary to begin with? Is there a way of ensuring also that
the topology is maintained throughout?

Best wishes,

Michel
