Arrangement on the sphere is not formally supported. The code that handles the general case has been generalized, but code that handles special cases is still missing.
In general the same guidelines that apply to arrangement in the plane also applies to arrangement on the sphere. CGAL::Arr_consolidated_curve_data_traits_2<Traits,Data>. You can extend an edge (more precisely, a halfedge) using CGAL::Arr_extended_dcel<Traits,VData,HData,FData,V,H,F> or the general technique described in Section
Extending the Dcel. There are examples to do either.

Hello,
I'm wondering if there's a straightforward way to modify the arrangement structure on a sphere such that the vertices/edges in the arrangement have additional information from the curves that are used to create them. Essentially I am looking to add annotations to the arrangement.
I would like to replace Curve_2 with a structure that has an annotation (e.g., a label) and have vertices/edges in the arrangement keep a list of the labels of the curves that pass through them, but I don't know if there is already a clear way to do this.
Thanks,
Evan
