      Zhang, Cheng; Zhao, Shuang (The Eurographics Association, 2020)
      Many real-world materials such as sand, snow, salt, and rice are comprised of large collections of grains. Previously, multiscale rendering of granular materials requires precomputing light transport per grain and has ...

      Meng, Xiaoxu; Zheng, Quan; Varshney, Amitabh; Singh, Gurprit; Zwicker, Matthias (The Eurographics Association, 2020)
      Real-time denoising for Monte Carlo rendering remains a critical challenge with regard to the demanding requirements of both high fidelity and low computation time. In this paper, we propose a novel and practical deep ...
    • Temporal Normal Distribution Functions 

      Tessari, Lorenzo; Hanika, Johannes; Dachsbacher, Carsten; Droske, Marc (The Eurographics Association, 2020)
      Specular aliasing can make seemingly simple scenes notoriously hard to render efficiently: small geometric features with high curvature and near specular reflectance result in tiny lighting features which are difficult to ...

      Dachsbacher, Carsten; Pharr, Matt (The Eurographics Association, 2020)
    • High-Resolution Neural Face Swapping for Visual Effects 

      Naruniec, Jacek; Helminger, Leonhard; Schroers, Christopher; Weber, Romann M. (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      In this paper, we propose an algorithm for fully automatic neural face swapping in images and videos. To the best of our knowledge, this is the first method capable of rendering photo-realistic and temporally coherent ...
    • Semi-Procedural Textures Using Point Process Texture Basis Functions 

      Guehl, Pascal; Allègre, Remi; Dischler, Jean-Michel; Benes, Bedrich; Galin, Eric (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      We introduce a novel semi-procedural approach that avoids drawbacks of procedural textures and leverages advantages of datadriven texture synthesis. We split synthesis in two parts: 1) structure synthesis, based on a ...
    • Practical Product Sampling by Fitting and Composing Warps 

      Hart, David; Pharr, Matt; Müller, Thomas; Lopes, Ward; McGuire, Morgan; Shirley, Peter (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      We introduce a Monte Carlo importance sampling method for integrands composed of products and show its application to rendering where direct sampling of the product is often difficult. Our method is based on warp functions ...
    • A Comprehensive Theory and Variational Framework for Anti-aliasing Sampling Patterns 

      Öztireli, A. Cengiz (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      In this paper, we provide a comprehensive theory of anti-aliasing sampling patterns that explains and revises known results, and introduce a variational optimization framework to generate point patterns with any desired ...
    • Photorealistic Material Editing Through Direct Image Manipulation 

      Zsolnai-Fehér, Károly; Wonka, Peter; Wimmer, Michael (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Creating photorealistic materials for light transport algorithms requires carefully fine-tuning a set of material properties to achieve a desired artistic effect. This is typically a lengthy process that involves a trained ...
    • Can't Invert the CDF? The Triangle-Cut Parameterization of the Region under the Curve 

      Heitz, Eric (The Eurographics Association and John Wiley & Sons Ltd., 2020)
