Hello,
I'm trying to get a minimal example of a weighted alpha shape to work in 2d.
However the example programs in the manual consist of only typedefs. I use
simple double precision arithmatic, so it becomes:



If I use these and try to insert RT::Weighted_point into an AS instance, I
get compiler errors saying the 


The 3D version apparently has a different template structure, where points
are derived as
CGAL::Regular_triangulation_euclidean_traits_3<K>::Weighted_point;
This type is not present in the
CGAL::Weighted_alpha_shape_euclidean_traits_2<K>, there is a
typedef ... Point; present in the header-file, but it gives the same
compiler-error when used.
Does anyone have a working example file from which I can kickstart?

Many thanks,
Johan Hidding
