是否有可能使用一個向量opengl頂點數組？

Question

我希望我的課Vector3f存儲我的立方體（由三角形構成）的索引指針。

繼承人什麼我會推向向量。

vector<Vector3f> I; 

    I.push_back(Vector3f(1, 0, 2));  //front 
    I.push_back(Vector3f(2, 0, 3)); 
    I.push_back(Vector3f(4, 5, 7));   //back 
    I.push_back(Vector3f(7, 5, 6)); 
    I.push_back(Vector3f(0, 4, 3));  //left 
    I.push_back(Vector3f(3, 4, 7));  
    I.push_back(Vector3f(5, 1, 6));  //right 
    I.push_back(Vector3f(6, 1, 2)); 
    I.push_back(Vector3f(7, 6, 3));  //up 
    I.push_back(Vector3f(3, 6, 2)); 
    I.push_back(Vector3f(1, 0, 5));  //down 
    I.push_back(Vector3f(5, 0, 4)); 

頂點數組可以從類讀取嗎？

假設你Vector3f是POD

&I[0]會給你一個float *它可以傳遞給glBufferData
