Thank you for your quick response.  It's reassuring to know that I''m not duplicating functionality that exists elsewhere in CGAL.

Best,

Looking at Chapter 35: 3D Surface Mesh Generation, I'd like to reproduce Example 35.3.1: Meshing an Implicit Surface.

While trivial to get the provided example code up and running, I am having trouble extracting a discrete mesh suitable for visualization via OpenGL.

Any wisdom regarding how to extract a list of finite vertices and facets from the resulting CGAL::Complex_2_in_triangulation_3 from CGAL::make_surface_mesh(...) would be greatly appreciated.  I find the iterators in this instance to be very confusing, and while I'm sure I can figure this out fairly quickly, the level of complexity has me wondering if I've missed something obvious and want to make sure any code I write is in like with the proper utilization of the CGAL library.

Thanks in advance for your time.

Hi Sebastian,

We are aware of the fact that a function that extracts a Polyhedron_3
out of the Complex_2_in_triangulation_3 is a missing feature.

So for the moment it is as complex as you feel it.
