This is code of print_faceVertices

 

void print_faceVertices( Face_handle* f )

{

Ccb_halfedge_circulator ec_start = (*f)->outer_ccb();

Ccb_halfedge_circulator ec = ec_start;

do

{

print_endpoint(ec,false);

} while ( ++ec != ec_start);//fim do while

}//fim print_faceVertices

 

So, in this case, f is a Face_handle. I'll try change function to receive a Face_iterator, but I don't know how Ccb_haledge_circulator will works.

 

This is the code of print_endpoint:

 

void print_endpoint(Halfedge_handle e, bool is_src)

{

std::cout << "\t";

if ( is_src )

{

if ( e->has_source() )//se aresta tem incio

std::cout << "x = " << e->source()->point().x()

<< ", y = " << e->source()->point().y() << std::endl;

else

std::cout << "ponto ao infinito" << std::endl;

}

else

{

if ( e->has_target() )//se aresta tem fim

std::cout << "x = " << e->target()->point().x()

<< ", y = " << e->target()->point().y() << std::endl;

else

std::cout << "ponto ao infinito" << std::endl;

}

}//fim print_endpoint

Perhaps making use of the Facet_iterator "fit" that you increment, would have the desired effect?
As in: print_faceVertices( &fit );

And to be sure to grab only bounded faces, use bounded_faces_begin() and bounded_faces_end().
Then, be sure to read the documentation of vd.bounded_face() to understand why the program do as you
describe.
