Hi Laurent, 

thanks for your kind reply. This (the bolded) is exactly what I had in mind. I am extremely grateful that you have this in 3.8, since what I had in 3.6.1 fused some boundaries that were proximate to each other (e.g. it closed separable meshing about one of the Sylvian fissures). 

I am going to try the latest version, and get back to you if I run into problems tweaking the density class (which is likely :-) ). 

Rest assured that if I am successful,  I will mention CGAL prominently in my papers that document this effort, which may include a couple of MICCAI workshops: the Mesh Processing  and the Systems and Architectures for Computer-assisted Interventions workshops.  

Warm wishes, 

Michel

What do you mean by "conform to the input PLC"? The tetrahedral mesh generator
in CGAL can remesh a polyhedron and respect its sharp edges (that is new in
CGAL-3.8).

As for the density, you can create a special model of the concept
MeshCriteria_3. For a client of GeometryFactory, I have writen such a criteria
class that reads the sizing field from a 3D scalar image, and ensure that for
each tetrahedron in the meshing domain, its size is smaller than the value in
the image at the center of the tetrahedron.
