Hi Sebastien,

Thank you very much for your kindly reply. Is there any good method to pass
double data to this kind of function? 

On the other hand, I have tested the example "mesh_implicit_domains.cpp"
(with integer data passed in) but found it can't generate multiple domains
meshes with the given feature. For example, by this way:

int main()
{
// Define functions
//Function f1(&torus_function);
//Function f2(&sphere_function<5>);
//Function f3(&sphere_function<2>);
        Function f1(&cube_function<-1,0,0,2>);
        Function f2(&cube_function<1,0,0,2>);
Function_vector v;
v.push_back(&f1);
v.push_back(&f2);
//v.push_back(&f3);
// Domain (Warning: Sphere_3 constructor uses square radius !)
Mesh_domain domain(v, K::Sphere_3(CGAL::ORIGIN, 5.*5.), 1e-6);
// Set mesh criteria
Facet_criteria facet_criteria(30, 0.2, 0.0001); // angle, size,
approximation


The output mesh is only one cube. I expect 3 sub-domains: one large sphere
with two small cubes inside it.

Thanks,
Tang Laoya
