WebMicrofacet BRDF is a perfect mirror. I.e., light reflects if and only if m = H. Mathematically, BRDF is a scaled dirac delta δ m ( H, m) So the perfect mirror is your model in the beginning 1 - but only for the specular BRDF! If you are trying to see, if including the diffuse BRDF into your BRDF is a perfect mirror, then this assumption does ... WebAug 25, 2024 · If necessary, change the mode from grayscale to RGB.
