I'm afraid it is not going to be possible. The AFSR package is using the

3D Delaunay triangulation as search space for possible triangles.

As your input mesh is most likely not a subset of a Delaunay

triangulation, it would first require a modification of the code

to handle the general triangulation type. Then the seeding would also

need to be modified as well as the candidate queue.

So it is a lot of modifications and theoretically it is not even

guaranteed that you could get a valid result without adding extra

points (in 3D constrained triangulation does not always exists).

I agree this is an interesting problem but I don't have a working

solution off the shelf.

Would dropping the island be a solution?
