WebI am implementing anisotropic GGX BRDF and have encountered strange behaviour of my implementation. I thought that if I compare the microfacet distribution function I have with the one of an isotropic GGX, then they should be equal when the anisotropy parameter is 0. I haven't been able to do that, though. Here is the GGX formula I have used: WebSmith's shadow masking function G 1 gives the fraction of microfacets with normal w h that are visible from direction w.
