摘要
简要说明计算机图形学光照模型理论 ,讨论由扰动函数作用后物体表面法向量的计算公式和意义 ,介绍对物体表面细节的凹凸真实性处理过程中几个重要参数 .
Theory of illumination model in computer graphics is described summarily. The calculation formulas of object surface normal after action of a perturbation function, and their meanings are discussed. Finally, several key parameters in the process of treatment of bump reality of object surface fine details are described too.
