SUMMARY:Fast-MSX: Fast Multiple Scattering Approximation
DESCRIPTION:Technical Communications, Technical Papers\n\nEnrique Rosales 
 (Huawei) and Fatemeh Teimury, Joshua Horacsek, Aria Salari, Xuebin Qin, Ad
 i Bar-Lev, Xiaoqiang Zhe, and Ligang Liu (Huawei Technologies)\n\nClassica
 l microfacet theory suffers from energy loss on materials with high roughn
 ess due to the single bounce assumption of most microfacet models. When ro
 ughness is high, there is a large chance of multiple scattering occurring 
 among the microfacets of the surface. Without explicitly modelling for thi
 s behaviour, rough surfaces appear darker than they should. To address thi
 s issue, we present a novel method to estimate the multiple scattering con
 tribution from a second light bounce. Our method is inspired by Zipin's ge
 ometric construction approach, which simplifies the calculation of the lig
 ht transport inside a V-groove cavity. Our experimental results demonstrat
 e that our method is visually pleasing, physically plausible, and artifact
 -free compared to recent multiple scattering works. Additionally, the low 
 computational cost makes our model suitable for real-time rendering.\n\nRe
