    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. ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • MAM 2019: Frontmatter 

    Klein, Reinhard; Rushmeier, Holly (Eurographics Association, 2019)
  • Towards a Principled Kernel Prediction for Spatially Varying BSSRDFs 

    Elek, Oskar; Krivánek, Jaroslav (The Eurographics Association, 2018)
    While the modeling of sub-surface translucency using homogeneous BSSRDFs is an established industry standard, applying the same approach to heterogeneous materials is predominantly heuristical. We propose a more principled ...
  • Deep Dual Loss BRDF Parameter Estimation 

    Boss, Mark; Groh, Fabian; Herholz, Sebastian; Lensch, Hendrik P. A. (The Eurographics Association, 2018)
    Surface parameter estimation is an essential field in computer games and movies. An exact representation of a real-world surface allows for a higher degree of realism. Capturing or artistically creating these materials is ...
  • Towards Physically Based Material Appearance in the Thermal Infrared Spectrum: A Short Survey 

    Haraké, Laura; Burkard, Eva (The Eurographics Association, 2018)
    In the context of photorealistic rendering, global illumination mainly relies on material models from the visible spectrum, whereas thermal infrared signatures receive only little attention. This paper outlines physical ...
  • Perception of Car Shape Orientation and Anisotropy Alignment 

    Filip, Jiri; Kolafová, Martina (The Eurographics Association, 2018)
    The color designers are used to introduce customized product design, visually communicating the unique impression of a car. They always carefully observe harmony of color and body shape to obtain desired visual impression. ...
  • A Method for Fitting Measured Car Paints to a Game Engine's Rendering Model 

    Kneiphof, Tom; Golla, Tim; Weinmann, Michael; Klein, Reinhard (The Eurographics Association, 2018)
    Car paints are visually complex materials that are of great importance for numerous real-time applications, including not only the game and movie industries but also virtual prototyping and design as well as advertisement. ...
  • Towards Practical Rendering of Fiber-Level Cloth Appearance Models 

    Alejandre, Adrian; Aliaga, Carlos; Marco, Julio; Jarabo, Adrian; Muñoz, Adolfo (The Eurographics Association, 2018)
    Accurate representation of realistic cloth appearance is of high importance in many industry fields such as entertainment and textile design. However, microstructure of fibers and their optical properties generate very ...
  • Image-based Fitting of Procedural Yarn Models 

    Saalfeld, Alina; Reibold, Florian; Dachsbacher, Carsten (The Eurographics Association, 2018)
    While common in real life, rendering fiber and cloth accurately is challenging. Recent fiber-based, procedural rendering approaches proved to be able to capture a great amount of details of real yarn. However, the current ...
  • Iso Photographic Rendering 

    Porral, Philippe; Lucas, Laurent; Muller, Thomas; Randrianandrasana, Joël (The Eurographics Association, 2018)
    In the field of computer graphics, the simulation of the visual appearance of materials requires an accurate computation of the light transport equation. Consequently, material models need to take into account various ...
  • A Simple Diffuse Fluorescent BBRRDF Model 

    Jung, Alisa; Hanika, Johannes; Marschner, Steve; Dachsbacher, Carsten (The Eurographics Association, 2018)
    Fluorescence - the effect of a photon being absorbed at one wavelength and re-emitted at another - is present in many common materials such as clothes and paper. Yet there has been little research in rendering or modeling ...
