Question

当我执行我的程序时

C：\ Users \ me \ Documents \ projectCGALII \ build \ Debug＆gt; test.exe pig.obj

我得到了6个交叉点，当它在Meshlab中被检查时它说4个交叉点。这是我的计划：

void  countSelfIntersection(const char* filename)
{
    OpenMesh(filename, pm);
    vcg::tri::UpdateTopology<PMesh>::FaceFace(pm);
    std::vector<PMesh::FaceType *> intersections;
    bool SelfIntersect = tri::Clean<PMesh>::SelfIntersections(pm, intersections);

    std::cout << "Count Intersection: " << intersections.size() << std::endl;

    for (std::vector<PMesh::FaceType *>::iterator it = intersections.begin(); it != intersections.end(); it++)
    {
        PMesh::FaceType *face = *it;
        for (int i = 0; i < 3; ++i)
        {
            std::cout << "Vertex(" <<i<<")"<< std::dec <<(int) face->cV0(i) << " " << std::dec << (int)face->cV1(i) << " " << std::dec << (int)face->cV2(i) << std::endl;
        }

        std::cout<<std::endl;


    }

}


int main(int argc, char* argv[])
{
    nonManinfoldEdge(argv[1]);
    return 0;
}

是结果中重复的面孔？如何像meshlab一样得到正确的结果？哪个是打印每个面或顶点属性的更好方法，以检查是否存在重复的面？如果它们存在，如何删除重复的面孔？

解决！
