      The efficiency of Monte Carlo algorithms for light transport simulation is directly related to their ability to importance-sample the product of the illumination and reflectance in the rendering equation. Since the optimal ...
    • Parallel Multiple-Bounce Irradiance Caching 

      Jones, Nathaniel L.; Reinhart, Christoph F. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Building designers rely on predictive rendering techniques to design naturally and artificially lit environments. However, despite decades of work on the correctness of global illumination rendering techniques, our ability ...
    • Line Sampling for Direct Illumination 

      Billen, Niels; Dutré, Philip (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Computing direct illumination efficiently is still a problem of major significance in computer graphics. The evaluation involves an integral over the surface areas of the light sources in the scene. Because this integral ...
    • Improving the Dwivedi Sampling Scheme 

      Meng, Johannes; Hanika, Johannes; Dachsbacher, Carsten (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Despite recent advances in Monte Carlo rendering techniques, dense, high-albedo participating media such as wax or skin still remain a difficult problem. In such media, random walks tend to become very long, but may still ...
    • A Phenomenological Model for Throughfall Rendering in Real-time 

      Weber, Yoann; Jolivet, Vincent; Gilet, Guillaume; Nanko, Kazuki; Ghazanfarpour, Djamchid (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      This paper aims at rendering interactive visual effects inherent to complex interactions between trees and rain in real-time in order to increase the realism of natural rainy scenes. Such a complex phenomenon involves a ...
    • Solid Angle Sampling of Disk and Cylinder Lights 

      Gamito, Manuel N. (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      A new unbiased sampling approach is presented, which allows the direct illumination from disk and cylinder light sources to be sampled with a uniform probability distribution within their solid angles, as seen from each ...
    • Perceptually Motivated BRDF Comparison using Single Image 

      Havran, Vlastimil; Filip, Jiri; Myszkowski, Karol (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Surface reflectance of real-world materials is now widely represented by the bidirectional reflectance distribution function (BRDF) and also by spatially varying representations such as SVBRDF and the bidirectional texture ...
    • Eurographics Symposium on Rendering 2016: Frontmatter 

      Elmar Eisemann; Eugene Fiume (The Eurographics Association and John Wiley & Sons Ltd., 2016)
    • AVOCADO: Visualization of Workflow-Derived Data Provenance for Reproducible Biomedical Research 

      Stitz, Holger; Luger, Stefan; Streit, Marc; Gehlenborg, Nils (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      A major challenge in data-driven biomedical research lies in the collection and representation of data provenance information to ensure that findings are reproducibile. In order to communicate and reproduce multi-step ...
    • From Visual Exploration to Storytelling and Back Again 

      Gratzl, Samuel; Lex, Alexander; Gehlenborg, Nils; Cosgrove, Nicola; Streit, Marc (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      The primary goal of visual data exploration tools is to enable the discovery of new insights. To justify and reproduce insights, the discovery process needs to be documented and communicated. A common approach to documenting ...
