Hello programmers,

I have a question since I'm not a professional C++ programmer. I'm
trying to apply the 3D envelope example 32.3.3 in

http://www.cgal.org/Manual/last/doc_html/cgal_manual/Envelope_3/Chapter_main.html

but I'm taking the planes from a polyhedron, and I have them in the type
Plane_3 through the iterator Polyhedron::begin() to end(). The example
takes them in the form Surface_3(Plane_3()), how can I do this
transformation? I tried to use std::transform for this but I failed.
The example provides it using the 4 coefficients of a plane, I can see
these coefficients of my Plane_3 object on a cout stream, but I can't
extract them alone one by one.

Could you please either tell me the correct transformation method for
this or tell me how to extract the coefficients from my Plane_3 object?

Thank you,
Samer Afach
