I looked at Mesh_criteria_3.h, Mesh_facet_criteria_3.h and
Mesh_cell_criteria_3.h. As far as I understand, these are the default
meshing criteria defined in CGAL package for Mesh_3 process.
This is how Mesh_cell_criteria_3's constructor looks like:
Mesh_cell_criteria_3(const FT& radius_edge_bound,
const FT& radius_bound)
so, we realize that radius_edge_bound and radius_bound are functors.
Now, going back to
CGAL-3.5/examples/Mesh_3/mesh_polyhedral_domain.cpp, is it possible to
define the following and expect this to just work?
typedef K::FT FT;
typedef FT (Function)(const Point&);
FT function_1 (const Point& p)
{
const FT x1=p.x();
const FT y1=p.y();
const FT z1=p.z();
return x1+y1+z1+1;
}
and then in main.cpp,
int main()
{
// ...
Cell_criteria cell_criteria(function_1, 0.2);
// ...
}
I appreciate your feedback.
Thanks,
-Ramin
