thanks for confirming that I do need to modify the sphere_function, but I
tried adding a variable to the sphere_function parameters, as:

FT sphere_function (const Point& p, K::FT squared_radius)
{ return CGAL::squared_distance(p, Point(CGAL::ORIGIN))-squared_radius; }

and it no longer compiled because the Mesh_domain constructor didn't like
the sphere_function any more... I'm confused how to change the radius with a
variable since I'm not actually calling the sphere function myself. How do I
pass a variable to the sphere function to be the radius?
