      Jakob, Wenzel; Puppo, Enrico (Eurographics Association, 2019)

    • Eurographics Symposium on Rendering - Experimental Ideas and Implementations: Frontmatter 

      Jakob, Wenzel; Hachisuka, Toshiya (The Eurographics Association, 2018)

    • Eurographics Symposium on Rendering: Frontmatter 

      Jakob, Wenzel; Hachisuka, Toshiya (The Eurographics Association and John Wiley & Sons Ltd., 2018)

    • A Low-Dimensional Function Space for Efficient Spectral Upsampling 

      Jakob, Wenzel; Hanika, Johannes (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We present a versatile technique to convert textures with tristimulus colors into the spectral domain, allowing such content to be used in modern rendering systems. Our method is based on the observation that suitable ...

    • Material and Lighting Reconstruction for Complex Indoor Scenes with Texture-space Differentiable Rendering 

      Nimier-David, Merlin; Dong, Zhao; Jakob, Wenzel; Kaplanyan, Anton (The Eurographics Association, 2021)
      Modern geometric reconstruction techniques achieve impressive levels of accuracy in indoor environments. However, such captured data typically keeps lighting and materials entangled. It is then impossible to manipulate the ...

    • Neural BTF Compression and Interpolation 

      Rainer, Gilles; Jakob, Wenzel; Ghosh, Abhijeet; Weyrich, Tim (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      The Bidirectional Texture Function (BTF) is a data-driven solution to render materials with complex appearance. A typical capture contains tens of thousands of images of a material sample under varying viewing and lighting ...

    • Practical Product Path Guiding Using Linearly Transformed Cosines 

      Diolatzis, Stavros; Gruson, Adrien; Jakob, Wenzel; Nowrouzezahrai, Derek; Drettakis, George (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Path tracing is now the standard method used to generate realistic imagery in many domains, e.g., film, special effects, architecture etc. Path guiding has recently emerged as a powerful strategy to counter the notoriously ...

    • Quantifying the Error of Light Transport Algorithms 

      Celarek, Adam; Jakob, Wenzel; Wimmer, Michael; Lehtinen, Jaakko (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      This paper proposes a new methodology for measuring the error of unbiased physically based rendering algorithms. The current state of the art includes mean squared error (MSE) based metrics and visual comparisons of ...

    • Unified Neural Encoding of BTFs 

      Rainer, Gilles; Ghosh, Abhijeet; Jakob, Wenzel; Weyrich, Tim (The Eurographics Association and John Wiley & Sons Ltd., 2020)
      Realistic rendering using discrete reflectance measurements is challenging, because arbitrary directions on the light and view hemispheres are queried at render time, incurring large memory requirements and the need for ...

    • Wide Gamut Spectral Upsampling with Fluorescence 

      Jung, Alisa; Wilkie, Alexander; Hanika, Johannes; Jakob, Wenzel; Dachsbacher, Carsten (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Physically based spectral rendering has become increasingly important in recent years. However, asset textures in such systems are usually still drawn or acquired as RGB tristimulus values. While a number of RGB to spectrum ...
