    • Estimating Homogeneous Data-driven BRDF Parameters from a Reflectance Map under Known Natural Lighting 

      Cooper, Victoria L.; Bieron, James C.; Peers, Pieter (The Eurographics Association, 2019)
      In this paper we demonstrate robust estimation of the model parameters of a fully-linear data-driven BRDF model from a reflectance map under known natural lighting. To regularize the estimation of the model parameters, we ...
    • Neural Appearance Synthesis and Transfer 

      Mazlov, Ilya; Merzbach, Sebastian; Trunz, Elena; Klein, Reinhard (The Eurographics Association, 2019)
      Appearance acquisition is a challenging problem. Existing approaches require expensive hardware and acquisition times are long. Alternative ''in-the-wild'' few-shot approaches provide a limited reconstruction quality. ...
    • What is the Reddening Effect and does it really exist? 

      Clausen, Olaf; Marroquim, Ricardo; Fuhrmann, Arnulph; Weigand, Holger (The Eurographics Association, 2019)
      The simulation of light-matter interaction is a major challenge in computer graphics. Particularly challenging is the modelling of light-matter interaction of rough surfaces, which contain several different scales of ...
    • Rendering Transparent Materials with a Complex Refractive Index: Semi-conductor and Conductor Thin Layers 

      Gerardin, Morgane; Holzschuch, Nicolas; Martinetto, Pauline (The Eurographics Association, 2019)
      During physical simulation of light transport, we separate materials between conductors and dielectrics. The former have a complex refractive index and are treated as opaque, the latter a real one and are treated as ...
    • On Visual Attractiveness of Anisotropic Effect Coatings 

      Filip, Jiří; Kolafová, Martina (The Eurographics Association, 2019)
      With the global trend in customer preference towards achromatic car colors, color designers in coating industry strive to create novel design-critical appearances based on novel effect pigments. At microscopic scale, the ...
    • MAM 2019: Frontmatter 

      Klein, Reinhard; Rushmeier, Holly (Eurographics Association, 2019)
    • Spectral Rendering with the Bounded MESE and sRGB Data 

      Peters, Christoph; Merzbach, Sebastian; Hanika, Johannes; Dachsbacher, Carsten (The Eurographics Association, 2019)
      In a recent journal paper, we introduced a technique to represent reflectance spectra by an arbitrary number of Fourier coefficients. As a special case, we converted tristimulus data to three Fourier coefficients. After ...
    • Fresnel Equations Considered Harmful 

      Hoffman, Naty (The Eurographics Association, 2019)
      Microfacet shading models in film and game production have long used a simple approximation to the Fresnel equations, published by Schlick in 1994. Recently a growing number of film studios have transitioned to using the ...
    • Comparative Study of Layered Material Models 

      Bati, Mégane; Pacanowski, Romain; Barla, Pascal (The Eurographics Association, 2019)
      The accurate reproduction of layered materials is an important part of physically-based rendering applications. Since no exact analytical model exists for any configuration of layer stacks, available models make approximations. ...
