Question

我正在尝试使用Polyhedron_3的CGAL的isotropic_remeshing方法。但我收到编译器错误，我不明白。这是一个最小的例子：

#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;

}

这会导致编译器错误：

我不确定我对isotropic_remeshing的调用有什么问题。在CGAL提供的示例中，使用了surface_mesh数据结构，但在我的情况下需要Polyhedron_3。谢谢你的帮助！

Answer 1

如文档所述，各向同性remesing需要face_index属性映射。在示例中，surface_mesh有一个默认的面部索引图，所以这个重载是有效的，但是Polyhedron_3没有，所以你必须为你的多面体创建一个并将它作为命名参数提供给函数。

您可以这样做：

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)));

此外，如果你使用split_edge，你会得到一个非三角形的面，当isotropic_remeshing需要对该区域进行三角剖分时，要么不要分割边缘，要么添加一条边来获得两个三角形而不是四边形。
