Triangulation of area in boost.Geometry

I use boost.Geometry to do some calculation resulting in an boost::geometry::model::multipolygon. I calculate it's area using boost::geometry::area. Besides using the numeric value I'd like to display the area for debugging/development purposes. I have a library to create and display meshes.

I understand that boost::geometry::area internally performs a triangulation of the multi_polygon for calculation of the area. Is there a way to access the calculated triangles for creating meshes? The default strategy (boost::geometry::strategy::area::surveyor) is used, but I can't find the place in the implementation where the triangulation is done.

In short, no. In Boost.Geometry any triangulation isn't performed to calculate the area of a Polygon. E.g. in cartesian coordinate system the Surveyor's Formula is used by default.
