Let me answer my own questions. It might help someone else.

Q. Is this criterion trying to put a bound on the distance between the 
facets and the "mesh domain" surface?
A. Yes

Q. Is the circumcenter located in the plane of facet and "facet surface 
center" located on the "mesh domain" surface?
A. Yes.

Hi,
I would appreciate it if someone explains how the curvature criterion is enforced in Curvature_size_criterion class (in mesh_standard_facet_criteria.h)

As I understand, in the "do_is_bad" member function of Curvature_size_criterion class, the distance between circumcenter of facet and "facet surface center" is calculated to ensure it does not exceed the allowed maximum value.

The following are ambiguous to me:
- Is this criterion trying to put a bound on the distance between the facets and the "mesh domain" surface? (in my case "mesh domain" is defined by a polyhedron)
- Is the circumcenter located in the plane of facet and "facet surface center" located on the "mesh domain" surface?

Also, any hint to a document that discusses this in more details is highly appreciated.

Thanks,
