Xu, ChaoWang, RuiZhao, ShuangBao, HujunZwicker, Matthias and Sander, Pedro2017-06-192017-06-1920171467-8659https://doi.org/10.1111/cgf.13221https://diglib.eg.org:443/handle/10.1111/cgf13221We present a new technique to jointly MIP-map BRDF and normal maps. Starting with generating an instant BRDF map, our technique builds its MIP-mapped versions based on a highly efficient algorithm that interpolates von Mises-Fisher (vMF) distributions. In our BRDF MIP-maps, each pixel stores a vMF mixture approximating the average of all BRDF lobes from the finest level. Our method is capable of jointly MIP-mapping BRDF and normal maps, even with high-frequency variations, at real-time while preserving high-quality reflectance details. Further, it is very fast, easy to implement, and requires no precomputation.I.3.7 [Computer Graphics]Three Dimensional Graphics and RealismColorshadingshadowingand texture10.1111/cgf.13221027-034
