    • Efficient Ray Tracing Through Aspheric Lenses and Imperfect Bokeh Synthesis 

      Joo, Hyuntae; Kwon, Soonhyeon; Lee, Sangmin; Eisemann, Elmar; Lee, Sungkil (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present an efficient ray-tracing technique to render bokeh effects produced by parametric aspheric lenses. Contrary to conventional spherical lenses, aspheric lenses do generally not permit a simple closed-form solution ...

    • Forward Light Cuts: A Scalable Approach to Real-Time Global Illumination 

      Laurent, Gilles; Delalandre, Cyril; Rivière, Grégoire de La; Boubekeur, Tamy (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      We present Forward Light Cuts, a novel approach to real-time global illumination using forward rendering techniques. We focus on unshadowed diffuse interactions for the first indirect light bounce in the context of large ...

    • Perceptually Motivated BRDF Comparison using Single Image 

      Havran, Vlastimil; Filip, Jiri; Myszkowski, Karol (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      Surface reflectance of real-world materials is now widely represented by the bidirectional reflectance distribution function (BRDF) and also by spatially varying representations such as SVBRDF and the bidirectional texture ...

    • A Phenomenological Model for Throughfall Rendering in Real-time 

      Weber, Yoann; Jolivet, Vincent; Gilet, Guillaume; Nanko, Kazuki; Ghazanfarpour, Djamchid (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      This paper aims at rendering interactive visual effects inherent to complex interactions between trees and rain in real-time in order to increase the realism of natural rainy scenes. Such a complex phenomenon involves a ...

    • Product Importance Sampling for Light Transport Path Guiding 

      Herholz, Sebastian; Elek, Oskar; Vorba, Jiří; Lensch, Hendrik; Křivánek, Jaroslav (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      The efficiency of Monte Carlo algorithms for light transport simulation is directly related to their ability to importance-sample the product of the illumination and reflectance in the rendering equation. Since the optimal ...
