SUMMARY:Successive Height Preintegration for a Height-Interdependent Path 
 Formulation of Multiple Bounces in Smith Microfacet BRDFs
DESCRIPTION:Siyuan Zhang (Chiba University), Takuya Funatomi (Kyoto Univer
 sity), Yuki Fujimura and Yasuhiro Mukaigawa (Nara Institute of Science and
  Technology), and Hiroyuki Kubo (Chiba University)\n\nClassic microfacet m
 odels for rendering account only for single-bounce light, leading to energ
 y loss. We present a novel multiple-bounce Smith microfacet BRDF with a he
 ight-interdependent formulation, successive height preintegration, and an 
 improved BRDF evaluation method. Our model can conserve energy well and ac
 hieves low variance with negligible bias.\n\nInterest Area: Research & Edu
 cation\n\nKeyword: Artificial Intelligence/Machine Learning, Modeling, Rea
 l-Time, Rendering\n\nRegistration Category: Full Conference Supporter, Ful
 l Conference\n\nSession Chair: Jeppe Revall Frisvad (Technical University 
 of Denmark)\n\n
