这篇文章中描述的任何命令都不会用来操作逐像素光照，你可以通过自己定义的顶点和片段编程来实现这个效果。

For these you don't use any of the commands described here, instead you define your own vertex and fragment programs where you do all lighting, texturing and anything else yourself.

可编程图形处理器允许用户编写运行在其上的顶点着色程序与片断着色程序，取代内置的固定功能渲染流水线，实现定制的渲染算法。

The programmable GPU permits developers to write vertex shaders and fragment shaders running on it, to replace the fixed function pipeline, and to employ custom rendering algorithms.
