Web我们使用 Cook-Torrance BRDF 的法线分布函数(NDF)生成采样向量及其散射强度，该函数将法线和视角方向作为输入。由于我们在卷积环境贴图时事先不知道视角方向，因此 Epic Games 假设视角方向——也就是镜面反射方向——总是等于输出采样方向，以作进一步近似。 WebThe two terms in BRDF are responsible for diffuse lighting and specular lighting, based on Energy Conservation, the sum of coefficients of these two terms should equals 1, in our case, k_d + F = 1.0. (F, which is Fresnel term, takes care of the specular ratio)

The bidirectional reflectance distribution function (BRDF; ) is a function of four real variables that defines how light is reflected at an opaque surface. It is employed in the optics of real-world light, in computer graphics algorithms, and in computer vision algorithms. The function takes an incoming light direction, , and outgoing direction, (taken in a coordinate system where the surface normal lies …
