Dear all,

I have a problem dealing with the segment Voronoi diagram (SVD): some faces 
of endpoint were NOT reported when I iterate all faces. For example, after 
building the SVD of 3 segments A, B, and C (see below), I iterated all faces 
(of endpoints and inner segment) using Face_iterator. Surprisingly, the faces 
of A's endpoints were not shown.

The phenomenon only existed when the endpoint has only ONE neighbor (say, B, 
or C in the case). If there are 2 or more neighbors, the endpoint's face is 
reported.

I wonder if this is a program's bug or author's intended style?

Thanks

Khuong

Subject: [cgal-discuss] point location with arr_circle_segment_traits

When I try to use the standard point location query with my traits it don't
work cause I've the following error:

/usr/local/include/CGAL/Arr_point_location/Arr_lm_nearest_neighbor.h ‘class
CGAL::Arr_circle_segment_traits_2<CGAL::Cartesian<CGAL::Quotient<CGAL::MP_Float>
>, true>’ has no member named ‘approximate_2_object’

So how can I perform a point location function when I'm working with the
arr_circle_segment_traits?--
