It is possible using a custom items traits (second template parameter).
The concept is documented here:
http://doc.cgal.org/latest/Polyhedron/classPolyhedronItems__3.html

For an example see how ids are added to simplices in CGAL/Polyhedron_items_with_id_3.h

Note that using the class Surface_mesh would allow you to do property assignment at run-time.

Best,

Hi,

I would like to know if it is possible to derive a polyhedron_3 in such a way
that i can store a couple of extra information on the vertices (specifically
each vertex should have two additional variables associated with it, one of a
double type, and another one of long or int type).

any leads would be great! thanks in advance!
