Hi Matthias,

make sure you look in the right direction. Using the

Triangulation_euclidean_traits_xy_3 you projected the triangulation in

the xy plane. Followingly you should look along the z-axis to "see" a

Delaunay triangulation, which is the case (at least on my machine).

Might it be possible that you expected it to be projected on the

xz-plane? Your data set sort of suggests that. In this case you see edge

intersections, but that's of course a completely correct behavior.

hope this helped
