    • 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 ...
