Hi,

I am using CGAL to generate 3d meshes for simple geometries such as a sphere
with a spherical hole in it. I followed CGAL examples using implicit
functions to define the surfaces of my mesh. In the output (.mesh) file,
among other things, I get a list of triangles corresponding to the triangles
of the surface mesh. Each triangle is given by 3 nodes id, and a fourth
field which is always 1 for me. Is there a way to tell CGAL to print out a
surface id as fourth field? Like 1 if the triangle belongs to the outer
surface of the sphere and 2 for the inner surface (hole)? I believe that
field is used for coloring by medit, but I want to use it to know what
boundary condition to apply in my simulation.

Thanks,
Jean-Luc
