WebWe would like to show you a description here but the site won’t allow us. Web因为前边讲了在Unity中如何实现一个BRDF——简单来说就是把公式抄到Shader里，于是这篇文章则主要从原理角度来讲一讲基于物理的BRDF公式为什么长那个样子。本篇文章主要是整理一下去年（2024）十二月底写的关于基于微表面模型的BRDF的一些东西，主要依据的是两篇经典论文：一篇是Cook-Torrance模型 ...
WebBRDF. BRDF是双向反射分布函数（Bidirectional Reflectance Distribution Function，BRDF）用来定义给定入射方向上的辐射照度（irradiance），如何影响给定出射方向上的辐射率（radiance）。更笼统地说，它描述了入射光线经过某个表面反射后如何在各个出射方向上分布。也可理解 ... http://www.joshbarczak.com/blog/?p=272
The bidirectional reflectance distribution function (BRDF; $${\displaystyle f_{\text{r}}(\omega _{\text{i}},\,\omega _{\text{r}})}$$ ) is a function of four real variables that defines how light is reflected at an opaque surface.
