Researchers at NVIDIA presented a new paper “An Analytic BRDF for Materials with Spherical Lambertian Scatterers” at Eurographics Symposium on Rendering 2021 (EGSR), June 29-July 2, introducing a new BRDF for dusty/diffuse surfaces. Our new Lambert-sphere BRDF (right) accurately and efficiently models the reflectance of a porous microstructure consisting of Lambertian spherical particles. Most rough…
