Dear CGAL experts, 


I would like to use the Triangulated Surface Mesh Simplification algorithm to modify a triangulated model of the skull base, in a manner that keeps the evolving skull surface in close proximity to a set of triangulated surfaces of the cranial holes (foramina). In other words, if we don't impose this type of constraint, the decimation tends to make these holes arbitrarily big, which is the opposite of what we want. Is there a simple way to use this code, or somehow modify it, to consider the faces of a second surface B (holes) as a constraint for the simplification of surface A (cranial bone)? 


Thanks for your kind support.
