Hi list,

I have several question about Mesh_3.

1. I'm generating isosurface by implicit function. It requires that
the center of the sphere be inside of the mesh. The question is, given
an arbitrary mesh, how can I find such a point?

2. Due to the first problem(I guess), the mesher seems to be sampling
a lot at a specific spot on the surface, making the mesh very dense at
that spot. While the generated mesh is self-intersection free by
construction, the exported .off is not(because of the precision
issue). I have set the precision to 17-digits and it doesn't help. I
guess one approach is to give a lower bound on the facet_size, but I
coudln't find such a parameter. Another approach is to simplify the
mesh, but I'm worried this might lose some details of the mesh.

Best,
Zesen
