Joint masking-shadowing function
Nettet因为，此处推导出的 BRDF 只计算一次弹射，需要将多次弹射的射线从该模型中移除，我们通过引入 shadowing 函数来移除多次弹射。实践上我们使用 masking-shadowing 函 … Nettet9. okt. 2024 · G1为微平面在单个方向（光照方向l和观察方向v）上可见比例，一般代表遮蔽函数(masking function)或阴影函数(shadowing function) G2为微平面在光照方向l和观察方向v两个方向上可见比例，一般代表联合遮蔽函数(joint masking-shadowing function) 在实践中G2由G1推导而来

This is a percentage of all the light that penetrates a surface (i.e. isn’t specularly reflected) rather than a percentage of the total light that hits a surface. A value of 1.0 means that 100% of the light that penetrates the surface is transmitted through.
