    • Combining Point and Line Samples for Direct Illumination 

      Salesin, Katherine; Jarosz, Wojciech (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We develop a unified framework for combining point and line samples in direct lighting calculations. While line samples have proven beneficial in a variety of rendering contexts, their application in direct lighting has ...

    • Microfacet Model Regularization for Robust Light Transport 

      Jendersie, Johannes; Grosch, Thorsten (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Today, Monte Carlo light transport algorithms are used in many applications to render realistic images. Depending on the complexity of the used methods, several light effects can or cannot be found by the sampling process. ...

    • Orthogonal Array Sampling for Monte Carlo Rendering 

      Jarosz, Wojciech; Enayet, Afnan; Kensler, Andrew; Kilpatrick, Charlie; Christensen, Per (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      We generalize N-rooks, jittered, and (correlated) multi-jittered sampling to higher dimensions by importing and improving upon a class of techniques called orthogonal arrays from the statistics literature. Renderers typically ...
