Color, Material, Lighting

【Color, Material, Lighting】

　　The material and lighting parameters are used to control the built-in vertex lighting. Vertex lighting is the standard Direct3D/OpenGL lighting model that is computed for each vertex.

　　material & parameters 参数用于控制vertex lighting。

　 Lighting on turns it on. Lighting is affected by Material block, ColorMaterial and SeparateSpecular commands.

　　Lighting on 命令开启顶点光照。Lighting受Material、ColorMaterial、SeparateSpecular命令的影响。

　　Per-pixel lights are usually implemented with custom vertex/fragment programs and don't use vertex lighting. 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.

　　Per-pixel 光照通过通过vertex/fragment 程序来实现，它们不使用顶点光照。Per-pixel光照不使用上述的任何命令，你需要定义自己的vertex & fragment 程序，在那里你要做lighting、texturing等所有的事。
