    • 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 ...

    • Deep Portrait Lighting Enhancement with 3D Guidance 

      Han, Fangzhou; Wang, Can; Du, Hao; Liao, Jing (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      Despite recent breakthroughs in deep learning methods for image lighting enhancement, they are inferior when applied to portraits because 3D facial information is ignored in their models. To address this, we present a novel ...

    • Moving Basis Decomposition for Precomputed Light Transport 

      Silvennoinen, Ari; Sloan, Peter-Pike (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      We study the problem of efficient representation of potentially high-dimensional, spatially coherent signals in the context of precomputed light transport. We present a basis decomposition framework, Moving Basis Decomposition ...

    • Optimised Path Space Regularisation 

      Weier, Philippe; Droske, Marc; Hanika, Johannes; Weidlich, Andrea; Vorba, Jirí (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      We present Optimised Path Space Regularisation (OPSR), a novel regularisation technique for forward path tracing algorithms. Our regularisation controls the amount of roughness added to materials depending on the type of ...

    • PosterChild: Blend-Aware Artistic Posterization 

      Chao, Cheng-Kang; Singh, Karan; Gingold, Yotam (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      Posterization is an artistic effect which converts continuous images into regions of constant color with smooth boundaries, often with an artistically recolored palette. Artistic posterization is extremely time-consuming ...

    • Rendering Point Clouds with Compute Shaders and Vertex Order Optimization 

      Schütz, Markus; Kerbl, Bernhard; Wimmer, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2021)
      In this paper, we present several compute-based point cloud rendering approaches that outperform the hardware pipeline by up to an order of magnitude and achieve significantly better frame times than previous compute-based ...
