我正在尝试使用VCG
库编写简单的程序
但是我什至无法通过VS 2010中的编译。
我从官方页面复制了示例文件,但此行失败
class MyMesh : public vcg::tri::TriMesh< std::vector<MyVertex>, std::vector<MyFace> , std::vector<MyEdge> > {};
编译器说
Error 10 error C2248: 'vcg::tri::TriMesh<Container0,Container1,Container2>::TriMesh' : cannot access private member declared in class 'vcg::tri::TriMesh<Container0,Container1,Container2>'...meshes\meshprocessing.h 24 1 Meshes
这是我完整的meshprocessing.h代码
#include<vcg/complex/complex.h>
#include<vcg/complex/append.h>
#include<vcg/complex/algorithms/clean.h>
#include<vcg/complex/algorithms/hole.h>

class MyVertex; class MyEdge; class MyFace;
struct MyUsedTypes : public vcg::UsedTypes<vcg::Use<MyVertex> ::AsVertexType,
vcg::Use<MyEdge> ::AsEdgeType,
vcg::Use<MyFace> ::AsFaceType>{};
class MyVertex : public vcg::Vertex< MyUsedTypes, vcg::vertex::Coord3f, vcg::vertex::Normal3f, vcg::vertex::BitFlags >{};
class MyFace : public vcg::Face< MyUsedTypes, vcg::face::FFAdj, vcg::face::VertexRef, vcg::face::BitFlags > {};
class MyEdge : public vcg::Edge< MyUsedTypes> {};
class MyMesh : public vcg::tri::TriMesh< std::vector<MyVertex>, std::vector<MyFace> , std::vector<MyEdge> > {};
class MeshProcessing
{
private:
MyMesh mesh;
pcl::PolygonMesh polygonMesh;
public:
MeshProcessing(pcl::PolygonMesh mesh);
MyMesh pclMeshtoVcgMesh();
MyMesh reorientNormals(MyMesh mesh);
};
我不知道该怎么办,将不胜感激。
编辑:
#include "MeshProcessing.h"
MeshProcessing::MeshProcessing(pcl::PolygonMesh mesh){
MeshProcessing::polygonMesh=mesh;
}
MyMesh MeshProcessing::pclMeshtoVcgMesh(){
MyMesh vcgMesh;
int verticeCount;
int triangleCount;
pcl::PointCloud<pcl::PointXYZ> tmp_cloud;
pcl:fromROSMsg(polygonMesh.cloud,tmp_cloud);
vcgMesh.Clear();
verticeCount=tmp_cloud.width*tmp_cloud.height;
vcg::tri::Allocator<MyMesh>::AddVertices(vcgMesh,verticeCount);
for(int i=0;i<verticeCount;i++){
vcgMesh.vert[i].P()=vcg::Point3f(tmp_cloud.points[i].x,tmp_cloud.points[i].y,tmp_cloud.points[i].z);
}
triangleCount=polygonMesh.polygons.size();
vcg::tri::Allocator<MyMesh>::AddFaces(vcgMesh, triangleCount);
for(int i=0;i<triangleCount;i++){
vcgMesh.face[i].V(0)=&vcgMesh.vert[polygonMesh.polygons[i].vertices[0]];
vcgMesh.face[i].V(1)=&vcgMesh.vert[polygonMesh.polygons[i].vertices[1]];
vcgMesh.face[i].V(2)=&vcgMesh.vert[polygonMesh.polygons[i].vertices[2]];
}
printf("Input mesh vn:%i fn:%i\n",vcgMesh.VN(),vcgMesh.FN());
return vcgMesh;
}
MyMesh reorientNormals(MyMesh mesh){
bool orientable=true;
bool oriented=false;
vcg::tri::Clean<MyMesh>::RemoveNonManifoldFace(mesh);
vcg::tri::Clean<MyMesh>::OrientCoherentlyMesh(mesh,oriented,orientable);
vcg::tri::UpdateNormal<MyMesh>::PerVertexNormalizedPerFace(mesh);
vcg::tri::UpdateNormal<MyMesh>::PerVertexFromCurrentFaceNormal(mesh);
return mesh;
}
最佳答案
private:
// TriMesh cannot be copied. Use Append (see vcg/complex/trimesh/append.h)\
TriMesh operator =(const TriMesh & m){assert(0);return TriMesh();}
TriMesh(const TriMesh & ){}
从VCG库中的base.h复制/粘贴。这是一个标准技巧,它带有令人讨厌的错误消息,激发了C++ 11的
= delete
synax。由于您是从TriMesh派生的,因此您必须声明自己的名称,因为编译器生成的代码无法工作。固定:class MyMesh : public yadayada...
{
private:
MyMesh operator=(const TriMesh &) /* = delete */;
MyMesh(const TriMesh &) /* = delete */;
};
