基于扰动函数的凸凹映射技术

The Technique of Bump-mapping Based on Disturbing Function

本文结合凸凹映射技术的基本原理,探讨了凸凹映射技术在球面上的具体应用,并给出了以b(u,v)=sinusinv为扰动函数的橘子的绘制的具体方法。

In regard to the basic principle of the technique of bump- mapping, this paper studies its application in the surface of sphere. An example based on disturbing function, b （u, v） = sinusinv, is given.
