Hi All:

I have a set of points in the three dimentional space, where a triangulation using CGAL library was computed. How Can I know which are the most external tetrahedrons? is to say, the tetrahedrons which have at least one external face. Are there functions or any form to know that? Is possible to iterate only these kind of elements?

thanks

A.
