Hello!
I am new on the mailing list and i just started to use cgal. 

I have some simple questions about converting iterators to geometric 
objects. 

I am using the voronoi 2D adapors.
I iterate through the vertices and then through the halfedges using the
Halfedge_around_vertex_circulator cit, 

i can check with cit->is_ray() and cit->is_segment() if the halfedge si 
finite or infinite, but how can i make a ray out of a infinite halfedge in 
the sense that i can intersect it with another ray or segment. I tried to 
find answers in the manual, but I got stuck. 

Thank you very much
