Hi there,

 

             In the example code “Polygon_mesh_processing/corefinement_difference_remeshed.cpp” , there is this method to get the constrained edges after the difference between 2 meshes are computed.

 

 

 

/// start of code

            

  //create a property on edges to indicate whether they are constrained

  Mesh::Property_map<edge_descriptor,bool> is_constrained_map =

    mesh1.add_property_map<edge_descriptor,bool>("e:is_constrained", false).first;

 

  // update mesh1 to contain the mesh bounding the difference

  // of the two input volumes.

  bool valid_difference =

    PMP::corefine_and_compute_difference(mesh1,

                                         mesh2,

                                         mesh1,

                                         params::all_default(), // default parameters for mesh1

                                         params::all_default(), // default parameters for mesh2

                                         params::edge_is_constrained_map(is_constrained_map));

 

/// end of code

 

 

              In my case, I wanted to use the Polyhedron class to perform the exact same function. But I have no idea how to set the property_map properly. Is there anyone that can guide me thru the process? Thanks!

 

Regards

Calvin
