在`render`方法中，我们必须在渲染之前启用此VBO并在完成后禁用它。
```java
// 绘制网格
glBindVertexArray(getVaoId());
glEnableVertexAttribArray(0);
glEnableVertexAttribArray(1);
glEnableVertexAttribArray(2);
glDrawElements(GL_TRIANGLES, getVertexCount(), GL_UNSIGNED_INT, 0);
// 恢复状态
glDisableVertexAttribArray(0);
glDisableVertexAttribArray(1);
glDisableVertexAttribArray(2);
glBindVertexArray(0);
glBindTexture(GL_TEXTURE_2D, 0);
glVertexAttribPointer(2, 3, GL_FLOAT, false, 0, 0);

现在我们已经完成了对`Mesh`类的修改，可以修改代码来使用纹理坐标或固定的颜色。因此，我们需要像这样修改片元着色器：
