    • Challenges in Appearance Capture and Predictive Modeling of Textile Materials 

      Castillo, Carlos; Aliaga, Carlos; López-Moreno, Jorge (The Eurographics Association, 2017)
      The appearance of cloth is the result of complex light interactions within the structures present in textile materials, particularly challenging due to their multi-scale nature. In addition to the inherent complexity of ...
    • 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 ...
    • Diffraction Prediction in HDR Measurements 

      Lucat, Antoine; Hegedus, R.; Pacanowski, Romain (The Eurographics Association, 2017)
      Modern imaging techniques have proved to be very efficient to recover a scene with high dynamic range values. However, this high dynamic range can introduce star-burst patterns around highlights arising from the diffraction ...
    • 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 ...
    • 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 ...
    • Image-based Remapping of Material Appearance 

      Sztrajman, Alejandro; Krivánek, Jaroslav; Wilkie, Alexander; Weyrich, Tim (The Eurographics Association, 2017)
      Digital 3D content creation requires the ability to exchange assets across multiple software applications. For many 3D asset types, standard formats and interchange conventions are available. For material definitions, ...
    • Isotropic BRDF Measurements with Quantified Uncertainties 

      Hegedus, R.; Lucat, A.; Redon, J.; Pacanowski, R. (The Eurographics Association, 2016)
      Image-based BRDF measurements on spherical material samples present a great opportunity to shorten significantly the acquisition time with respect to more traditional, non-multiplexed measurement methods for isotropic ...
    • Linear Transport Theory and Applications to Rendering 

      Jakob, Wenzel (The Eurographics Association, 2014)
      In this talk, I will give an overview of one-dimensional Linear Transport Theory, which concerns itself with the study of random scattering and absorption processes and the inference of large-scale behavior from simple ...
    • The MAM2014 Sample Set 

      Rushmeier, Holly (The Eurographics Association, 2014)
      Modeling the material appearance of physical materials requires access to the materials. Sets of identical physical material models were prepared for distribution at the workshop on material appearance modeling 2014 ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
