Hi,

First congratulation on the forum interface, it's more convenient.

Second I have a problem with make_surface_mesh when reconstructing from an
implicit function. When I want higher resolution, i.e. I decrease the radius
or distance bounds in the criteria, it fails with:

CGAL::Polyhedron_incremental_builder_3<HDS>::
lookup_halfedge(): input error: facet 2960 shares a halfedge from vertex
3581 to vertex 351 with facet 1784.

So I thought instead of using Exact_predicates_inexact_constructions_kernel
to use Exact_predicates_exact_constructions_kernel, but I had compilation
problems. I fixed them with changing in:

Complex_2_in_triangulation_3_polyhedron_builder.h

double top_z = 
=>
Tr::Geom_traits::FT top_z

Implicit_surface_oracle_3.h, Sphere_oracle_3.h

const FT radius = CGAL::sqrt(squared_radius);
=>
const FT radius = CGAL::sqrt(CGAL::to_double(squared_radius));


, but when I ran it with the changes, it just ran forever.

I appreciate your help,
Thanks
