The following might work :

Delete from the C2T3::triangulation the vertices which are no longer
on the zero level set
Reinitialize a C2T3 with the updated triangulation
and call  again make_surface_mesh using :
- the C2T3
- the modified function
- an initial number of points equals to 0

I am working with implicit functions to which I make a zero-level surface. I want  to make these functions updatable – that is, I create a surface, and then I change the function in some area of space, and I want to re-create the surface. The change is relatively local, so it should affect only a (known) part of the mesh. Is there a possibility to maybe “erase” part of the surface and update it with the new function, using CGAL’s mesh generation?
