Hello everyone,

I'm trying to add several spheres with different radius. In the code, I'm
passing different radius values but it has no effect to the sphere. They all
have the same size. What I'm doing wrong? Please help me. 

Thanks. My Code;


FT sphere_function (Point_3 p) {
  const FT x2=p.x()*p.x(), y2=p.y()*p.y(), z2=p.z()*p.z();
  return x2+y2+z2-1;
}

void MainWindow::AddSphere(){
        

         Tr tr;            // 3D-Delaunay triangulation
  C2t3 c2t3 (tr);   // 2D-complex in 3D-Delaunay triangulation
  // defining the surface

  double radius = 1.0; //This is where I set the different radius values

  Surface_3 surface(sphere_function,             // pointer to function
          Sphere_3(CGAL::ORIGIN, radius)); // bounding sphere

 
 //Set criteria by given radius. 
  CGAL::Surface_mesh_default_criteria_3 Tr
criteria(radius*5.0,radius/4.0,radius/4.0);
 

   Polyhedron *sphere = new Polyhedron;

  CGAL::make_surface_mesh(c2t3, surface, criteria,
CGAL::Non_manifold_tag());

  CGAL::Complex_2_in_triangulation_3_polyhedron_builder C2t3, Polyhedron 
builder(c2t3);
  sphere->delegate(builder);

  Scene_item* item = new Scene_polyhedron_item(sphere);

  scene->addItem(item);
}
