    • 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 ...
    • Nonlinearly Weighted First-order Regression for Denoising Monte Carlo Renderings 

      Bitterli, Benedikt; Rousselle, Fabrice; Moon, Bochang; Iglesias-Guitian, Jose A.; Adler, David; Mitchell, Kenny; Jarosz, Wojciech; Novak, Jan (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We address the problem of denoising Monte Carlo renderings by studying existing approaches and proposing a new algorithm that yields state-of-the-art performance on a wide range of scenes. We analyze existing approaches ...
    • 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 ...
    • Sparse High-degree Polynomials for Wide-angle Lenses 

      Schrade, Emanuel; Hanika, Johannes; Dachsbacher, Carsten (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Rendering with accurate camera models greatly increases realism and improves the match of synthetic imagery to real-life footage. Photographic lenses can be simulated by ray tracing, but the performance depends on the ...
