    • 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 ...
