hi

I realized that when a gray-scale image contains pointy structures, 
setting the
angular bound to a certain number (say 30) will result in an endless 
refinement
process and eventually exhaust the system memory. To prevent this from 
happening,
I want to set a termination criterion when the surface mesh nodes exceed a
maximum node number. I checked the refine_mesh() function defined
in include/CGAL/Surface_mesher/Surface_mesher.h , in the debug mode,
it exposes the node number (tr.number_of_vertices) which can be used
for this purpose. However, I believe there must exist a more elegant way
to set this termination criterion outside of this function.

Can someone tell me what I should do to add this criterion to the surface
mesher example? ( examples/Surface_mesher/mesh_a_3d_gray_image.cpp)

thank you very much
