    • Extracting Microfacet-based BRDF Parameters from Arbitrary Materials with Power Iterations 

      Dupuy, Jonathan; Heitz, Eric; Iehl, Jean-Claude; Poulin, Pierre; Ostromoukhov, Victor (The Eurographics Association and John Wiley & Sons Ltd., 2015)
      We introduce a novel fitting procedure that takes as input an arbitrary material, possibly anisotropic, and automatically converts it to a microfacet BRDF. Our algorithm is based on the property that the distribution of ...

    • Fast Generation of Approximate Blue Noise Point Sets 

      Kalantari, Nima Khademi; Sen, Pradeep (The Eurographics Association and Blackwell Publishing Ltd., 2012)
      Poisson-disk sampling is a popular sampling method because of its blue noise power spectrum, but generation of these samples is computationally very expensive. In this paper, we propose an efficient method for fast generation ...
