摘要

提出了一种以二维微面取向分布为输入,生成四维双向反射分布函数(BRDF)的方法。这种方法与以前基于微面的BRDF模型的不同之处在于,它使用了一个简单的阴影项,这使得它可以处理非常普遍的微面分布,同时保持互易性和能量守恒。发电机显示在各种材料类型上。

A microfacet-based BRDF generator
A method is presented that takes as an input a 2D microfacet orientation distribution and produces a 4D bidirectional reflectance distribution function (BRDF). This method differs from previous microfacet-based BRDF models in that it uses a simple shadowing term which allows it to handle very general microfacet distributions while maintaining reciprocity and energy conservation. The generator is shown on a variety of material types.
