CGAL users discussion list

[Qianqian Fang <>]

Dear list:

for a project of mine, I need to modify a pre-made
tetrahedral mesh (output of CGAL 3D mesh generator)
by adding a bunch of additional 3D nodes. The new nodes
are outside of the existing mesh. I'd like to insert new
tetrahedra between the new nodes and the surface triangles
that have direct sight to the new nodes. It is important not
to insert any additional nodes aside from the ones I need.
The quality of the new elements are not important
and thus a quality-based refinement is not preferred.

I am wondering if anyone know if this is possible in
CGAL? it would be wonderful if you can point me to
the CGAL sample or share a code snippet to illustrate
how to implement.

thank you very much

Qianqian
