Thanks a lot... So I was checking out the delaunay segment diagram and I hope you could help me again...
I  am having hard time to traverse it. I see that there are lot of circulators and iterators but i cannot understand how to use it...

for example i want to circulate it face by face:
    SDG2::Finite_faces_iterator fit = sdg.finite_faces_begin();
    for( ; fit != sdg.finite_faces_end(); fit++)
    {
        SDG2::Face_handle v = fit;
        //where are the reference in the manual for the face handle?
        //what am i supposed to do now with v to get all the vertices of the face?
    }
 

Thanks again
bye

Hello, I need the voronoi diagram of a geometric 2D shape in order to calculate its
medial axis. So I was going through the CGAL manual, precisely at :

http://www.cgal.org/Manual/3.1/doc_html/cgal_manual/Segment_Voronoi_diagram_2/Chapter_main.html

and I figured out that i do not have the following headers: - Segment_Voronoi_diagram_filtered_traits_2.h
- Segment_Voronoi_diagram_hierarchy_2.h
 I installed CGAL 3.3.1 using the windows installer and I am running it on Vista
x64 with VS2008.

There has been some renaming of these classes since CGAL 3.1
(it's now Segment_Delaunay_*graph*_2), so you should use
the manual corresponding to the version of CGAL that you use.
