Per-vertex lighting effect of three types of light(directional light,point light and spot light) supported by Direct3D is realized using Microsoft Visual Studio,DirectX 9.0 and shader technique. And it is compared with standard graphics pipelining.

• 鉴于此；在Microsoft Visual Studio开发环境下；利用DirectX 9.；0软件包进行3D开发；结合顶点shader技术编程实现了Direct3D支持的三种灯光(平行光、点光、聚光)的顶点光照效果；并与使用标准图形管线实现的光照效果进行了对比。
