Anisotropy at a deeper level seems to be about the structured, often linear arrangement of particles within a material, which causes the light to interact differently based on its incident direction relative to these structures. When light hits these structured surfaces, the interaction is influenced by the microfacets' orientation, leading to reflections that are stretched or compressed in the structure's direction.

I have heard about things being isotropic and anisotropic and never really knew what the difference between the two was. The shiny ring we see in anisotropic materials makes a lot of sense now because of the importance of direction giving off a unique reflection.
