    • An Analytic BRDF for Materials with Spherical Lambertian Scatterers 

      d'Eon, Eugene (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      We present a new analytic BRDF for porous materials comprised of spherical Lambertian scatterers. The BRDF has a single parameter: the albedo of the Lambertian particles. The resulting appearance exhibits strong back ...
    • A Combined Scattering and Diffraction Model for Elliptical Hair Rendering 

      Benamira, Alexis; Pattanaik, Sumanta (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      Realistic hair rendering relies on fiber scattering models. These models are based on either ray tracing or on full wavepropagation through the hair fiber. Ray tracing can model most of the scattering phenomenon observed ...
