OPENGL中采用顶点数组索引方式绘制对象时，碰到下面的问题；
GLint face_indicies[6][9] = {
    {2,0,3 ,0,0,0 ,0,1,2 }, {1,3,0 ,0,0,0 ,3,2,1 }
    , {6,4,7 ,1,1,1 ,0,1,2 }, {5,7,4 ,1,1,1 ,3,2,1 }
    , {10,8,11 ,2,2,2 ,0,1,2 }, {9,11,8 ,2,2,2 ,3,2,1 }
};
GLfloat vertices[12][3] = {
{-252.866f,200.469f,-2.1247e-07f},{-246.616f,211.294f,2.1247e-07f},{-252.866f,200.469f,15.0f},
{-246.616f,211.294f,15.0f},{-246.616f,200.469f,-7.30884e-07f},{-252.866f,211.294f,7.30884e-07f},
{-246.616f,200.469f,15.0f},{-252.866f,211.294f,15.0f},{-255.991f,205.881f,-7.10543e-15f},
{-243.491f,205.881f,-7.10543e-15f},{-255.991f,205.881f,15.0f},{-243.491f,205.881f,15.0f}
};
GLfloat normals[3][3] = {
{0.866025f,-0.5f,0.0f},{0.866025f,0.5f,0.0f},{0.0f,-1.0f,0.0f}
};
GLfloat textures[4][2] = {
{0.0f,2.0f},{0.0f,1.0f},{1.0f,2.0f},
{1.0f,1.0f}
};

face_indicies[n]-----第n个三角形
face_indicies[][0-2]----顶点索引
face_indicies[][3-5]----法向索引
face_indicies[][6-8]----体贴坐标索引

采用顶点数组绘图：
glNormalPointer(GL_FLOAT, 0, m_pNormals);
glTexCoordPointer(.....);
glVertexPointer(.....);

glEnableClientState( GL_NORMAL_ARRAY);    
glEnableClientState( GL_TEXTURE_COORD_ARRAY);    
glEnableClientState( GL_VERTEX_ARRAY );    
glDrawElements( GL_TRIANGLES, number_face, GL_UNSIGNED_INT, indices );
glDisableClientState( GL_NORMAL_ARRAY);    
glDisableClientState( GL_TEXTURE_COORD_ARRAY);    
glDisableClientState( GL_VERTEX_ARRAY );    

目前glDrawElements函数只接受一组索引，比如，接受了顶点坐标的索引，那其他两个就无效，如果想绘制出完整的图形（包

括顶点、贴图坐标、法向），该怎么处理。我查阅了相关资料，glDrawElements所接受的索引应该是一个顶点对应一个法向量

、一个贴图坐标，上面的数据倒是可以拆分成，但是那样向绘制函数传送的数据量就会大很多，失去了索引的意义。有哪位兄

弟姐妹能给些建议。万分感谢！！！
