SUMMARY:Materials
DESCRIPTION:Technical Communications, Technical Papers\n\nA Micrograin BSD
 F Model for the Rendering of Porous Layers\n\nWe introduce a new BSDF mode
 l for the rendering of porous layers, as found on surfaces covered by dust
 , rust, dirt, or sprayed paint. \nOur approach is based on a distribution 
 of elliptical opaque micrograins, extending the Trowbridge-Reitz (GGX) dis
 tribution [Trowbridge1975,Walter2007] to handle por...\n\n\nSimon Lucas (U

 ultiple-bounce Smith Microfacet BRDFs using the Invariance Principle\n\nSm
 ith microfacet models are widely used in computer graphics to represent ma
 terials. Traditional microfacet models do not consider the multiple bounce
 s on microgeometries, leading to visible energy missing, especially on rou
 gh surfaces. Later, as the equivalence between the microfacets and volume

 \nMetaLayer: A Meta-learned BSDF Model for Layered Materials\n\nReproducin
 g the appearance of arbitrary layered materials has long been a critical c
 hallenge in computer graphics, with regard to the demanding requirements o
 f both physical accuracy and low computation cost. Recent studies have dem
 onstrated promising results by learning-based representations that i...\n\
