Hi, 

I also want to get the vertices Cartesian coordinates , I'm trying to put into pratice what M Duque wrote but when I write :

 CGAL::Object o = sdg.dual(eit2);

There's a compilation error  :

 error C2039: 'dual' : n'est pas membre de 'CGAL::Sdg2<Gt>'

which means 'dual' isn't member of 'CGAL::Sdg2<Gt>'
Can someone help me ?

Hello,

note that CGAL offers an adapter for the Segment Delaunay graph

Hi All,

I am using Segment Voronoi algorithm(Segment Delaunay Graph) to find the Voronoi edges.

I want to find out the 'voronoi vertices' i.e. those points where two or more voronoi edges meet.

I referred to the program /CGAL/examples/Segment_Delaunay_graph_2/sdg-voronoi-edges.cpp

It gives the edges according to       \                       /
       \         B         /
        \                  /
      C  -----------------  D
        /                 \
       /         A         \
      /                       \

i.e. it gives A, B, C & D.

My question is - how can I get the coordinates of the voronoi vertex formed due to ABC or BAD ?????? I want the cartesian x, y coordinates of those vertices.

This is kind of urgent. Can anybody please comment on this. All the inputs are highly appreciated.

Thanks & Regards,
Amit Pendharkar
