  • A Taxonomy of Bidirectional Scattering Distribution Function Lobes for Rendering Engineers 

    McGuire, Morgan; Dorsey, Julie; Haines, Eric; Hughes, John F.; Marschner, Steve; Pharr, Matt; Shirley, Peter (The Eurographics Association, 2020)
    We propose a taxonomy and terminology for rendering engineers to use in describing the main categories of mathematical lobes that are combined to implement bidirectional scattering distribution functions (BSDFs). Bringing ...
  • On the Nature of Perceptual Translucency 

    Gigilashvili, Davit; Thomas, Jean-Baptiste; Hardeberg, Jon Yngve; Pedersen, Marius (The Eurographics Association, 2020)
    Translucency is an appearance attribute used to characterize materials with some degree of subsurface light transport. Although translucency as a radiative transfer inside the medium is relatively well understood, translucency ...
  • Bonn Appearance Benchmark 

    Merzbach, Sebastian; Klein, Reinhard (The Eurographics Association, 2020)
    There is a general shortage of standardized comparisons in the field of appearance modeling. We therefore introduce a benchmark for assessing the quality of reflectance models on a dataset of high quality material measurements ...
  • The Problem of Entangled Material Properties in SVBRDF Recovery 

    Saryazdi, Soroush; Murphy, Christian; Mudur, Sudhir (The Eurographics Association, 2020)
    SVBRDF (spatially varying bidirectional reflectance distribution function) recovery is concerned with deriving the material properties of an object from one or more images. This problem is particularly challenging when the ...
  • A Genetic Algorithm Based Heterogeneous Subsurface Scattering Representation 

    Kurt, Murat (The Eurographics Association, 2020)
    In this paper, we present a novel heterogeneous subsurface scattering (sss) representation, which is based on a combination of Singular Value Decomposition (SVD) and genetic optimization techniques. To find the best ...
  • Improving Spectral Upsampling with Fluorescence 

    König, Lars; Jung, Alisa; Dachsbacher, Carsten (The Eurographics Association, 2020)
    Modern photorealistic rendering simulates spectral behaviour of light. Since many assets are still created in different RGB color spaces, spectral upsampling of the RGB colors to a spectral representation is required to ...
  • An Adaptive Metric for BRDF Appearance Matching 

    Bieron, James; Peers, Pieter (The Eurographics Association, 2020)
    Image-based BRDF matching is a special case of inverse rendering, where the parameters of a BRDF model are optimized based on a photograph of a homogeneous material under natural lighting. Using a perceptual image metric, ...
  • MAM - Eurographics 2020 Workshop on Material Appearance Modeling: Frontmatter 

    Klein, Reinhard; Rushmeier, Holly (The Eurographics Association, 2020)
  • 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. ...
  • 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 ...
  • 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 ...
  • 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. ...
  • 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 ...
