你可以在以下位置找到Demo的完整[源代码](http://learnopengl.com/code_viewer.php?code=advanced-lighting/deferred)，和几何渲染阶段的[顶点](http://learnopengl.com/code_viewer.php?code=advanced-lighting/deferred_geometry&type=vertex)和[片段](http://learnopengl.com/code_viewer.php?code=advanced-lighting/deferred_geometry&type=fragment)着色器，还有光照渲染阶段的[顶点](http://learnopengl.com/code_viewer.php?code=advanced-lighting/deferred&type=vertex)和[片段](http://learnopengl.com/code_viewer.php?code=advanced-lighting/deferred&type=vertex)着色器。

延迟着色法的其中一个缺点就是它不能进行[混合](../04 Advanced OpenGL/03 Blending.md)(Blending)，因为G缓冲中所有的数据都是从一个单独的片段中来的，而混合需要对多个片段的组合进行操作。延迟着色法另外一个缺点就是它迫使你对大部分场景的光照使用相同的光照算法，你可以通过包含更多关于材质的数据到G缓冲中来减轻这一缺点。
