[osg-users] osgUtil Delaunay and a bit complex intersecting constraints

Hi Community,

over the last 2 years I was working for a client on prototyping integrating
road network into terrains and I did it with the Delaunay triangulation
available in OSG, and for simple test demo cases is working fine (if you
are curious here some video
https://www.dropbox.com/s/jlwbzs00pv4ifur/TerrainTool-4.mp4?dl=0 ).

Now on the same topic again, and it is for real apps (OSG based) not
prototyping. And I need error free constrained triangulation. The one in
OSG gives me results like in the attached images (holes etc). I tried to
look at this CGAL lib but found it over-complicated (for me) to use and I
do prefer to stick with what we have in OSG. Anyone with some hints on
maybe how to work with complex constraints and osg delaunay? My code is
based on the depricated osgdelaunay example. Maybe something extra? Any
word will help!

Thanks a bunch as always!
