如何在OpenGL ES 1.1上用不同的纹理填充立方体的每一面？

GLuint textureIds[6];
glGenTextures(6, textureIds);

for (int i = 0; i < 6; i++) {
    glBindTexture(GL_TEXTURE_2D, textureIds[i]);
}

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);

for (int i = 0; i < 6; i++) {
    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, textureImages[i]);
}

GLfloat vertices[] = {
    // 前面
    -1.0f, -1.0f,  1.0f,
     1.0f, -1.0f,  1.0f,
     1.0f,  1.0f,  1.0f,
    -1.0f,  1.0f,  1.0f,
    // 背面
    -1.0f, -1.0f, -1.0f,
    -1.0f,  1.0f, -1.0f,
     1.0f,  1.0f, -1.0f,
     1.0f, -1.0f, -1.0f,
    // 其他面
    // ...
};

glEnableClientState(GL_VERTEX_ARRAY);
glVertexPointer(3, GL_FLOAT, 0, vertices);

// 前面
glBindTexture(GL_TEXTURE_2D, textureIds[0]);
glDrawArrays(GL_TRIANGLE_FAN, 0, 4);

// 背面
glBindTexture(GL_TEXTURE_2D, textureIds[1]);
glDrawArrays(GL_TRIANGLE_FAN, 4, 4);

// 其他面
// ...

glDisableClientState(GL_VERTEX_ARRAY);
