Dear all,

I would like to generate periodic 3D meshes of regions bounded by
implicit functions and so I was pleased to find examples such as [1]
that do almost exactly what I want. The problem that I'm having is
that cells in the meshes generated from this example are able to lie
across the bounding unit cube, but to use the meshes in finite element
simulations I need the faces of the cells to align with the boundaries
of the cube.

For example, the CGAL example [1] (with a different implciit function)
generates meshes like [cgal.jpg], but I would like one like
[gmsh.jpg].

I haven't been able to find a way to do this in CGAL. Is it possible?

Many thanks,
Matt
