Abstract
Realistic image synthesis is an important research goal in computer graphics. One important factor to achieve this goal is a bidirectional reflectance distribution function (BRDF) that mainly governs an appearance of an object. Many BRDF models have therefore been developed. A physically-based BRDF based on microfacet theory [Cook and Torrance 1982] is widely used in many applications since it can produce highly realistic images. The microfacetbased BRDF consists of three terms; a Fresnel, a normal distribution, and a geometric functions. There are many analytical and approximate models for each of these terms.
真实感图像合成是计算机图形学的一个重要研究方向。实现这一目标的一个重要因素是双向反射分布函数(BRDF)，它主要控制物体的外观。因此，开发了许多BRDF模型。基于microfacet理论的物理BRDF [Cook and Torrance 1982]由于可以产生高度逼真的图像，因此被广泛应用于许多应用中。基于微面的BRDF包括三个术语;菲涅耳分布，正态分布和几何函数。每个术语都有许多解析模型和近似模型。
