Hi Marc,

Thanks for the suggestion. I wrote a function to iterate on the vertices and counted them, and I still only ever get two, for both my test cases where I insert 4 for a tetrahedron and 8 for a 16cell:

https://github.com/acgetchell/CDT-plusplus/blob/master/src/Delaunay.h

https://github.com/acgetchell/CDT-plusplus/blob/master/unittests/SdTriangulationTest.cpp

With these results:

I can successfully make a tetrahedral triangulation with a Triangulation_3:

But not with a Delaunay_d:

https://github.com/acgetchell/CDT-plusplus/blob/master/unittests/SdTriangulationTest.cpp

In particular, it only generates 2 vertices, even in the DISABLED test case
that inserts 8.

Hello,

is the function number_of_vertices the only one giving you trouble? Did you try iterating on the vertices and counting them? I have a vague memory of a function, maybe this one, not working correctly, but not affecting the rest either.
