Hi.
This is Hasnine from Japan. according to the advice of Laurent I have
modified the CGAL/examples/Surface_mesher/mesh_an_implicit_function.cpp
by Adding #include <CGAL/Random.h> and CGAL::default_random =
CGAL::Random(0);

however, I have faces an compilation error. Do you have the same problem
!! Please advice me how to fix this.

Subject: [cgal-discuss] 3d surface mesher non deterministic


hi,

I tried to run
CGAL/examples/Surface_mesher/mesh_an_implicit_function.cpp and noticed
that each time I run the program, the output is slightly different.
The resulting mesh approximating the given geometry, in fact, has
different points and cells. 

Why is this process not deterministic? Is there a way to make it
deterministic?

greetings
