CGAL users discussion list

Hello,

For a polyhedron object in 3 dimensional space, is there a way in CGAL to
get the minimum and maximum z as a function of x and y? I want to give the
program the values of x and y, and return the maximum or minimum z if x
and y lie in the polyhedron. Does the envelope function do this?

I would be really thankful for an answer,

Regards,
Samer
