Hi Hardik,

Simple_parameterization.cpp and polyhedron_ex_parameterization.cpp do not use the same data structures to store the (u, v) values.
You need to adapt the code when you copy code from Simple_parameterization.cpp to polyhedron_ex_parameterization.cpp.

polyhedron_ex_parameterization.cpp stores the mesh in the class Polyhedron_ex defined in Polyhedron_ex.h.
I think that the next code should work:

double u = pVertex->halfedge()->u();

double v = pVertex->halfedge()->v();

Hi Laurent, 

Simple_parametrization.cpp access (uv) as follows:

    Polyhedron::Vertex_const_iterator pVertex;

    for (pVertex = mesh.vertices_begin();

        pVertex != mesh.vertices_end();

        pVertex++)

    {

        // (u,v) pair is stored in any halfedge

        double u = mesh_adaptor.info(pVertex->halfedge())->uv().x();

        double v = mesh_adaptor.info(pVertex->halfedge())->uv().y();

        std::cout << "(u,v) = (" << u << "," << v << ")" << std::endl;

    }

I get the following compiler error when I try the same:

/usr/local/soft/CGAL-4.2/examples/Surface_mesh_parameterization/polyhedron_ex_parameterization.cpp:517:33: error: no member named 'info' in

      'Parameterization_polyhedron_adaptor_ex'

        double u = mesh_adaptor.info(pVertex->halfedge())->uv().x();

polyehdron_ex_parametrization uses: #include "Parameterization_polyhedron_adaptor_ex.h"

and I could not find info() option in it.

Am I missing something ?

Thanks!

Dear Hardik,

I invite you to look at Simple_parameterization.cpp example that shows how to access (u, v) pairs.

Hello, 

I am trying to using polyhedron_ex_parameterization.cpp example in the Surface_mesh_parametrization

section. It only output an eps file. 

I need (u,v) coordinates for each and every vertex in the input .off file. How can I get it ?

Thanks for help!
