    • 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 ...

    • Real-time Image-based Lighting of Microfacet BRDFs with Varying Iridescence 

      Kneiphof, Tom; Golla, Tim; Klein, Reinhard (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      Iridescence is a natural phenomenon that is perceived as gradual color changes, depending on the view and illumination direction. Prominent examples are the colors seen in oil films and soap bubbles. Unfortunately, iridescent ...
