Question

我是C ++的新手

class BlenderMesh{
public:
    std::vector<double[3]>          vertex_vectors;
    std::vector<double[3]>          normal_vectors;
    std::vector<double[2]>          uv_vectors;
    std::vector<std::string>        texture_list;
    std::vector<int[6]>             face_indices;
    std::vector<int[3]>             normal_indices;
    std::vector<int[3]>             uv_indices;
                                    BlenderMesh();
                                    ~BlenderMesh();};

代码错误：mesh-＆gt; vertex_vectors.push_back（vertex）;

BlenderMesh::BlenderMesh(){}

BlenderMesh::~BlenderMesh(){}

BlenderMesh* mesh = new BlenderMesh();

PyObject* vertexVectors = PyList_GetItem(blenderObject,2);
unsigned int size_vertex_vectors = PyObject_Size(vertexVectors);
for (unsigned int i = 0; i < size_vertex_vectors; i++){
    double vertex[3];
    PyObject* pyVertex = PyList_GetItem(vertexVectors,i);
    PyObject* vertexX = PyTuple_GetItem(pyVertex,0);
    vertex[0] = PyFloat_AsDouble(vertexX);
    PyObject* vertexY = PyTuple_GetItem(pyVertex,1);
    vertex[1] = PyFloat_AsDouble(vertexY);
    PyObject* vertexZ = PyTuple_GetItem(pyVertex,2);
    vertex[2] = PyFloat_AsDouble(vertexZ);
    mesh->vertex_vectors.push_back(vertex);
    }

控制台：

已经过去四年了，但希望这对某人有帮助。由于某些原因，您无法创建包含对象本机列表的矢量对象（也许有人可以解释原因？）。

例如，当创建一个包含1'ns的18x2向量时，例如：

std::vector<double[2]> my_vector(18, {1.0, 1.0});

因此，您应该执行以下操作：

std::vector<vector<double>> my_vector(18, vector<double>(2,{1.0, 1.0});

myclass中的向量。错误：数组中的括号初始值设定项[-fpermissive]
