Hello,
Thanks, It works!!!

Yes. You are right.
You have two choices:

This method works fine. Thanks !!!
2. Use the first form of range<NextPolicies,Target>(...) described

The mechanisms of NextPolicies and Terget are a little obscur to me...
Today, I don't understand everything about this kind of stuffs.
Just a question :
Is there a third method where I can define the iterator and member of the
class Triangulation2<...> and define the inheritance between Triangulation_2
and Delaunay using boost?
That would let the Python binding looks more like the C++ original
library...
HTH,
Happy Being Helped!!!
Cyril
