简单光反射模型(Phong模型)的导出

the Deduction of the Simple Light Reflection Model(Phong Model)

简单光反射模型只考虑物体对直接光照的反射作用,而物体间的光反射作用,只用环境光来表示,Phong模型即为这样的一种模型。本文分别从光反射作用的各个组成部分来导出Phong模型。

The simple light reflection model with a view to reflection function that shines on the object . The light reflection function among the object is represented by the ambient light. The model of Phong acts as such a kind of model. This paper deduces the model of Phong from every part of the light reflection function.
