Как настроить вершины для прямоугольника?

Question

Мне нужно настроить вершины для прямоугольника - у меня есть квадратный пример, как бы изменить его, чтобы получить прямоугольник в 5 раз ширину и половину высоты?

/** The initial vertex definition */  
private float vertices[] = { 
        //Vertices according to faces 
        -1.0f, -1.0f, 1.0f, //v0 
        1.0f, -1.0f, 1.0f,  //v1 
        -1.0f, 1.0f, 1.0f,  //v2 
        1.0f, 1.0f, 1.0f,  //v3 

        1.0f, -1.0f, 1.0f,  // ... 
        1.0f, -1.0f, -1.0f, 
        1.0f, 1.0f, 1.0f, 
        1.0f, 1.0f, -1.0f, 

        1.0f, -1.0f, -1.0f, 
        -1.0f, -1.0f, -1.0f, 
        1.0f, 1.0f, -1.0f, 
        -1.0f, 1.0f, -1.0f, 

        -1.0f, -1.0f, -1.0f, 
        -1.0f, -1.0f, 1.0f, 
        -1.0f, 1.0f, -1.0f, 
        -1.0f, 1.0f, 1.0f, 

        -1.0f, -1.0f, -1.0f, 
        1.0f, -1.0f, -1.0f, 
        -1.0f, -1.0f, 1.0f, 
        1.0f, -1.0f, 1.0f, 

        -1.0f, 1.0f, 1.0f, 
        1.0f, 1.0f, 1.0f, 
        -1.0f, 1.0f, -1.0f, 
        1.0f, 1.0f, -1.0f, 
             }; 

Хорошо, так что я думаю, что настройки вершины правильно, но теперь мне нужно настроить нормалей текстуры и индексы:

/** The initial vertex definition */  
private float vertices[] = { 
        //Vertices according to faces 
        -1.0f, -.5f, 1.0f, //v0 
        4.0f, -.5f, 1.0f,  //v1 
        -1.0f, .5f, 1.0f,  //v2 
        4.0f, .5f, 1.0f,  //v3 

        4.0f, -.5f, 1.0f,  // 2... 
        4.0f, -.5f, -1.0f, 
        4.0f, .5f, 1.0f, 
        4.0f, .5f, -1.0f, 

        4.0f, -.5f, -1.0f, //3 
        -1.0f, -.5f, -1.0f, 
        4.0f, .5f, -1.0f, 
        -1.0f, .5f, -1.0f, 

        -1.0f, -.5f, -1.0f, //4 
        -1.0f, -.5f, 1.0f, 
        -1.0f, .5f, -1.0f, 
        -1.0f, .5f, 1.0f, 

        -1.0f, -.5f, -1.0f, //5 
        4.0f, -.5f, -1.0f, 
        -1.0f, -.5f, 1.0f, 
        4.0f, -.5f, 1.0f, 

        -1.0f, .5f, 1.0f, //6 
        4.0f, .5f, 1.0f, 
        -1.0f, .5f, -1.0f, 
        4.0f, .5f, -1.0f, 
             }; 

Любые предложения, как настроить их:

private float normals[] = { 
         // Normals 
         0.0f, 0.0f, 1.0f, 


        0.0f, 0.0f, -1.0f,

        0.0f, 0.0f, 1.0f, 
        0.0f, 0.0f, -1.0f,

        0.0f, 1.0f, 0.0f, 
        0.0f, -1.0f, 0.0f, 
             }; 

/** The initial texture coordinates (u, v) */

        0.0f, 0.0f, 
        0.0f, 1.0f, 
        1.0f, 0.0f, 
        1.0f, 1.0f, 

        0.0f, 0.0f, 
        0.0f, 1.0f, 
        1.0f, 0.0f, 
        1.0f, 1.0f, 

        0.0f, 0.0f, 
        0.0f, 1.0f, 
        1.0f, 0.0f,

        1.0f, 0.0f,

        0.0f, 0.0f, 
        0.0f, 1.0f, 
        1.0f, 0.0f, 
        1.0f, 1.0f, 
           }; 

/** The initial indices definition */ 
private byte indices[] = { 
        // Faces definition 
        0, 1, 3, 0, 3, 2,  // Face front 
        4, 5, 7, 4, 7, 6,  // Face right 
        8, 9, 11, 8, 11, 10, // ... 
        12, 13, 15, 12, 15, 14, 
        16, 17, 19, 16, 19, 18,
