    • Line Integration for Rendering Heterogeneous Emissive Volumes 

      Simon, Florian; Hanika, Johannes; Zirr, Tobias; Dachsbacher, Carsten (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Emissive media are often challenging to render: in thin regions where only few scattering events occur the emission is poorly sampled, while sampling events for emission can be disadvantageous due to absorption in dense ...
    • Minimal Warping: Planning Incremental Novel-view Synthesis 

      Leimkühler, Thomas; Seidel, Hans-Peter; Ritschel, Tobias (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Observing that many visual effects (depth-of-field, motion blur, soft shadows, spectral effects) and several sampling modalities (time, stereo or light fields) can be expressed as a sum of many pinhole camera images, we ...
    • Multiple Axis-Aligned Filters for Rendering of Combined Distribution Effects 

      Wu, Lifan; Yan, Ling-Qi; Kuznetsov, Alexandr; Ramamoorthi, Ravi (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Distribution effects such as diffuse global illumination, soft shadows and depth of field, are most accurately rendered using Monte Carlo ray or path tracing. However, physically accurate algorithms can take hours to ...
    • Practical Path Guiding for Efficient Light-transport Simulation 

      Müller, Thomas; Gross, Markus; Novák, Jan (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present a robust, unbiased technique for intelligent light-path construction in path-tracing algorithms. Inspired by existing path-guiding algorithms, our method learns an approximate representation of the scene's ...
    • Real-Time Linear BRDF MIP-Mapping 

      Xu, Chao; Wang, Rui; Zhao, Shuang; Bao, Hujun (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      We present a new technique to jointly MIP-map BRDF and normal maps. Starting with generating an instant BRDF map, our technique builds its MIP-mapped versions based on a highly efficient algorithm that interpolates von ...
    • Stochastic Light Culling for VPLs on GGX Microsurfaces 

      Tokuyoshi, Yusuke; Harada, Takahiro (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      This paper introduces a real-time rendering method for single-bounce glossy caustics created by GGX microsurfaces. Our method is based on stochastic light culling of virtual point lights (VPLs), which is an unbiased culling ...
    • Variance and Convergence Analysis of Monte Carlo Line and Segment Sampling 

      Singh, Gurprit; Miller, Bailey; Jarosz, Wojciech (The Eurographics Association and John Wiley & Sons Ltd., 2017)
      Recently researchers have started employing Monte Carlo-like line sample estimators in rendering, demonstrating dramatic reductions in variance (visible noise) for effects such as soft shadows, defocus blur, and participating ...
