    • 3D for Studying Reuse in 19th Century Cairo: the Case of Saint-Maurice Residence 

      Baillet, Vincent; Mora, Pascal; Cou, Corentin; Tournon-Valiente, Sarah; Volait, Mercedes; Granier, Xavier; Pacanowski, Romain; Guennebaud, Gaël (The Eurographics Association, 2021)
      3D restitution is now a well-known tool to validate hypotheses on historical buildings that do not exist anymore. The present project takes the method a step further in order to explore the art historical topic of ornament ...

    • Comparative Study of Layered Material Models 

      Bati, Mégane; Pacanowski, Romain; Barla, Pascal (The Eurographics Association, 2019)
      The accurate reproduction of layered materials is an important part of physically-based rendering applications. Since no exact analytical model exists for any configuration of layer stacks, available models make approximations. ...

    • Interactive Exploration of Vivid Material Iridescence based on Bragg Mirrors 

      Fourneau, Gary; Pacanowski, Romain; Barla, Pascal (The Eurographics Association and John Wiley & Sons Ltd., 2024)
      Many animals, plants or gems exhibit iridescent material appearance in nature. These are due to specific geometric structures at scales comparable to visible wavelengths, yielding so-called structural colors. The most vivid ...

    • On Learning the Best Local Balancing Strategy 

      Murray, David; Benzait, Sofiane; Pacanowski, Romain; Granier, Xavier (The Eurographics Association, 2020)
      Fast computation of light propagation using Monte Carlo techniques requires finding the best samples from the space of light paths. For the last 30 years, numerous strategies have been developed to address this problem but ...

    • Reconstruction of Sparse Hyperspectral BRDF Measurements Preserving Their Physical and Topological Properties 

      Margall, François; Ceolato, Romain; Coiro, Eric; Mavromatis, Sébastien; Pacanowski, Romain (The Eurographics Association, 2024)
      The measurement of hyperspectral bidirectional reflectance distribution function (BRDF) of a material is a key issue in physically based spectral rendering. We present here a device for measuring BRDF, enabling high spectral ...
