    Zhu, Junqiu; Xu, Yanning; Wang, Lu (The Eurographics Association and John Wiley & Sons Ltd., 2019)
    Microfacet theory is commonly used to build reflectance models for surfaces. While traditional microfacet-based models assume that the distribution of a surface's microstructure is continuous, recent studies indicate that ...
