将 Vertex_handles 获取到 delaunay 三角剖分的点

我想迭代 CGAL::Delaunay_triangulation_2 的所有顶点，但无法找到有关获取所有顶点句柄的文档。

我为此找到的文档解释了如何迭代三角测量。

typedef CGAL::Delaunay_triangulation_2<K> T;
typedef T::Vertex_handle Vh;
typedef T::Vertex_iterator Vi;
for (Vi vi = g.vertices_begin(); vi != g.vertices_end(); vi++) {
    // Vh v = how can I get this?
}

但是，我找不到有关如何从迭代器获取 Vertex_handle 的文档

原文

I want to iterate through all vertices of a CGAL::Delaunay_triangulation_2, but am unable to find documentation about getting all the vertex handles.

The documentation I found for this explained how to iterate through the triangulation.

typedef CGAL::Delaunay_triangulation_2<K> T;
typedef T::Vertex_handle Vh;
typedef T::Vertex_iterator Vi;
for (Vi vi = g.vertices_begin(); vi != g.vertices_end(); vi++) {
    // Vh v = how can I get this?
}

However, I cannot find documentation about how to get to the Vertex_handle from the iterator

好吧，我只是愚蠢。尝试了一些更随机的事情，发现迭代器实际上是句柄。当然，我在这里写完整篇文章后发现了这一点:-)

typedef CGAL::Delaunay_triangulation_2<K> T; 
typedef T::Vertex_handle Vh; 
typedef T::Vertex_iterator Vi; 
for (Vi vi = g.vertices_begin(); vi != g.vertices_end(); vi++) { 
    Vh v = vi;
}

Okay I was just stupid. Tried some more random things and got that the iterator actually is the handle. Of course I find this out after writing the whole post here :-)

typedef CGAL::Delaunay_triangulation_2<K> T; 
typedef T::Vertex_handle Vh; 
typedef T::Vertex_iterator Vi; 
for (Vi vi = g.vertices_begin(); vi != g.vertices_end(); vi++) { 
    Vh v = vi;
}
