\section{Output}

Parameterization methods compute $(u,v)$ fields for each vertex
of the input mesh, with the seam vertices being virtually duplicated (thanks
to \ccc{CGAL::Parameterization_mesh_patch_3<ParameterizationPatchableMesh_3>}).
To support this duplication,
\ccc{CGAL::Parameterization_polyhedron_adaptor_3<Polyhedron_3_>} stores
the result in the $(u,v)$ fields of the input mesh halfedges.
A $(u,v)$ pair is computed for
each inner vertex (i.e. its halfedges share the same $(u,v)$ pair),
while a $(u,v)$ pair is computed for each border halfedge.
The user has to iterate over the mesh halfedges to get the result.
Note that $(u,v)$ fields do not exist in \ccc{CGAL::Polyhedron_3<Traits>},
thus the output traversal is specific to the way the (u,v) fields are implemented by the adaptor.

\subsection{EPS Output Example}

\ccc{Complete_parameterization_example.cpp} is a complete parameterization
example which outputs the resulting parameterization to a EPS file. It gets the $(u,v)$ fields computed by a parameterization method over a \ccc{CGAL::Polyhedron_3<Traits>} mesh with a
\ccc{CGAL::Parameterization_polyhedron_adaptor_3<Polyhedron_3_>} adaptor:
