[Thierry Fredrich <>]

Starting from the example "info_insert_with_pair_iterator.cpp", I added the the vector V to become "std::vector<std::pair<Point, unsigned>> V;" and filled it with "V.push_back(std::make_pair(*rnd++, (unsigned)i));". Similar to the example  "parallel_insertion_in_delaunay_3.cpp". I 1) created a Lock_data_structure (seems to be mandantory for parallel execution) and 2) edited the constructor to "Triangulation T(V.begin(), V.end(), &locking_ds);"

The code could be found at: https://github.com/thierry3000/VBL/commit/e60d713f1d180a0d11e360b2528d61ed3d1a8047

What I get from the compiler error below is that the constructor does not accept more complex vector than just vectors of "Points" which actually makes sense. To come back to my origial question: how to overcome this and hand over a vector of std::pair like it is done in "info_insert_with_pair_iterator???

Thierry

P.S. : I am working with the CGAL release bundle 4.11.

It should be working. What did you try and what error did you get?

Dear all,

in principle, all I need is provided in the example (Triangulation_3/info_insert_with_pair_iterator.cpp), but to speed up my project I want to use a parallel form of it. "Triangulation_3/parallel_insertion_in_delaunay_3.ccp" seems to provide all pieces. However I cannot get the hang on how to merge these two examples.

I assume the crucial step is to insert "Points with additional information" into the Triangulation which breaks in my case since the constructor only accepts plain points. (error: no type named ‘type’ in ‘struct boost::enable_if<boost::is_convertible<std::pair<CGAL::Point_3<CGAL::Epick>, unsigned int>, CGAL::Point_3<CGAL::Epick> >, void>’)
But if I provide plain point, how can I convey the additional information like the "unsigned" in the example.

Is there any experienced user who tried similar things?
