Dear Stavros,

You may implement a fixed border mean value coordinates parameterization 
(Floater) using CGAL and a specific .off mesh 2D border by:

* Adding a class that will implement the border parameterization that you 
wish.
This class must be a model of BorderParameterizer_3 (see 
www.cgal.org/Manual/3.2/doc_html/cgal_manual/Surface_mesh_parameterization_ref/Concept_BorderParameterizer_3.html)
You may use the default circle or square border parameterizations as a starting 
point.

* Passing this new class as template parameter to 
CGAL::Square_border_arc_length_parameterizer_3 (Floater).
See Square_border_parameterization.cpp example to specify such a template 
parameter.

Best regards,

Laurent Saboret
