CGAL isotropic_remeshing с многогранником_3

/ 06 мая 2018

Я пытаюсь использовать метод isotropic_remeshing в CGAL с Многогранником_3. Но я получаю ошибки компилятора, которые я не понимаю. Это минимальный пример: 

#include <iostream>

#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
#include <CGAL/Polyhedron_3.h>
#include <CGAL/Polygon_mesh_processing/remesh.h>


typedef CGAL::Simple_cartesian<double>  Kernel;
typedef Kernel::Point_3                 Point_3;
typedef CGAL::Polyhedron_3<Kernel>      Meshtype;
typedef Meshtype::Halfedge_handle       Halfedge_handle;



int main()
{
    Meshtype* plane = new Meshtype;
    Halfedge_handle h = plane->make_triangle(Point_3(0.0, 0.0, 0.0),
                                            Point_3(1.0, 1.0, 0.0),
                                            Point_3(0.0, 1.0, 0.0));

    //split triangle at (p1, p3) edge and insert p2.
    Halfedge_handle h_new = plane->split_edge(h->next());
    h_new->vertex()->point() = Point_3(1.0, 0.0, 0.0);


    CGAL::Polygon_mesh_processing::isotropic_remeshing (
            faces(*plane),
            0.3,
            *plane);

    std::cout << plane->size_of_vertices();
    delete plane;

}

Это приводит к ошибке компилятора:

Я не уверен, что не так с моим вызовом isotropic_remeshing. В примерах, предоставленных CGAL, используется структура данных surface_mesh, но в моем случае необходим Polyhedron_3. Спасибо за любую помощь!

Как документировано, для изотропного времени требуется карта свойств face_index. В примерах для surface_mesh используется карта индекса лица по умолчанию, поэтому эта перегрузка работает, а Polyhedron_3 - нет, поэтому необходимо создать ее для многогранника и передать ее функции в качестве именованного параметра.

Вы можете сделать что-то вроде этого: 

typedef boost::graph_traits<Meshtype>::face_descriptor 
face_descriptor;
std::map<face_descriptor, std::size_t> fi_map;
std::size_t id =0;
BOOST_FOREACH(face_descriptor f, faces(plane))
{
  fi_map[f]=id++;
}
CGAL::Polygon_mesh_processing::isotropic_remeshing (
        faces(*plane),
        0.3,
        *plane,
        CGAL::parameters::face_index_map(
        boost::make_assoc_property_map(fi_map)));

Более того, если вы используете split_edge, вы получите грань, отличную от треугольника, когда isotropic_remeshing нуждается в триангуляции региона, поэтому либо не делите ребро, либо добавьте ребро, чтобы получить два треугольника вместо квадрата.

...
