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.
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。
Using vertex and fragment programs, it is possible to replace the traditional vertex projection and lighting equation used by real-time computer graphics hardware.
使用顶点和片元程序能够取代计算机图形硬件上使用的传统的顶点投影和光照公式。
It looks at each target face's direction as defined by it's vertex normals and calculates the new lighting solution by offsetting it with the information from the normal map.
它通过顶点法线所定义的方向察看每个目标面，然后根据来自法线贴图的信息通过补偿它来计算新的灯光效果。
