Material Appearance Modeling: Recent submissions

  • Kurt, Murat (The Eurographics Association, 2017)
    The Bidirectional Scattering Distribution Function (BSDF) describes the appearance of an optically thin, translucent material by its interaction with light at a surface point. Various BSDF models have been proposed to ...
  • Lucat, Antoine; Hegedus, R.; Pacanowski, Romain (The Eurographics Association, 2017)
    Modern imaging techniques have proved to be very efficient to recover a scene with high dynamic range values. However, this high dynamic range can introduce star-burst patterns around highlights arising from the diffraction ...
  • Holzschuch, Nicolas; Pacanowski, Romain (The Eurographics Association, 2017)
    For material acquisition, we use digital cameras and process the pictures. We usually treat the cameras as perfect pinhole cameras, with each pixel providing a point sample of the incoming signal. In this paper, we study ...
  • Castillo, Carlos; Aliaga, Carlos; López-Moreno, Jorge (The Eurographics Association, 2017)
    The appearance of cloth is the result of complex light interactions within the structures present in textile materials, particularly challenging due to their multi-scale nature. In addition to the inherent complexity of ...
  • Brok, Dennis den; Weinmann, Michael; Klein, Reinhard (The Eurographics Association, 2017)
    We present preliminary results on our effort to combine sparse and illumination-multiplexed acquisition of bidirectional texture functions (BTFs) for material appearance. Both existing acquisition paradigms deal with a ...
  • Merzbach, Sebastian; Weinmann, Michael; Klein, Reinhard (The Eurographics Association, 2017)
    When relighting digitized objects, strong color deviations can arise depending on the illumination conditions if the object’s reflectance is only captured in RGB. To guarantee color-correct simulations, it is therefore of ...
  • Marco, Julio; Serrano, Ana; Jarabo, Adrian; Masia, Belen; Gutierrez, Diego (The Eurographics Association, 2017)
    Computer-generated imagery is ubiquitous, spanning fields such as games and movies, architecture, engineering, or virtual prototyping, while also helping create novel ones such as computational materials. With the increase ...
  • Ribardière, M.; Meneveaux, D.; Bringier, B.; Simonot, L. (The Eurographics Association, 2017)
    This paper presents the use of Student’s T-Distribution (STD) with interfaced Lambertian (IL) microfacets. The resulting model increases the range of materials while providing a very accurate adjustment of appearance. STD ...
  • Sztrajman, Alejandro; Krivánek, Jaroslav; Wilkie, Alexander; Weyrich, Tim (The Eurographics Association, 2017)
    Digital 3D content creation requires the ability to exchange assets across multiple software applications. For many 3D asset types, standard formats and interchange conventions are available. For material definitions, ...
  • Reinhard Klein; Holly Rushmeier (Eurographics Association, 2017)
  • Filip, J.; Havran, V.; Myszkowski, K. (The Eurographics Association, 2016)
    BRDFs are currently used as a standard representation of material surface reflectance properties either in the from of tabulated measurements or a parametric model. However, the compression of tabulated representations as ...
  • Havran, Vlastimil (The Eurographics Association, 2016)
    We present our experiences with using an autocollimator to set up the surface reflectance measurement for both BRDF and BTF. Assuming the measured material appearance is put on a locally flat surface, the autocollimator ...
  • Weinmann, Michael; Klein, Reinhard (The Eurographics Association, 2016)
    In this paper, we propose a novel approach for recovering illumination and reflectance from a single image. Our approach relies on the assumption that the surface geometry has already been reconstructed and a-priori knowledge ...
  • Yu, Jiyang; Xu, Zexiang; Mannino, Matteo; Jensen, Henrik Wann; Ramamoorthi, Ravi (The Eurographics Association, 2016)
    We acquire the data-driven spatially-varying (SV)BRDF of a flat sample from only a small number of images (typically 20). We generalize the homogenous BRDF acquisition work of Nielsen et al., who derived an optimal minmal ...
  • Muñoz-Pandiella, I.; Bosch, C.; Mérillou, N.; Pueyo, X.; Mérillou, S; Patow, G. (The Eurographics Association, 2016)
    In this paper, we propose to discuss on one of the main challenges in realistic rendering of urban scenes: changes in appearance over time within a urban context. After studying the previous work on weathering techniques, ...
  • Dal Corso, Alessandro; Frisvad, Jeppe Revall; Kjeldsen, Thomas Kim; Bærentzen, Jakob Andreas (The Eurographics Association, 2016)
    Juice appearance is important to consumers, so digital juice with a slider that varies a production parameter or changes juice content is useful. It is however challenging to render juice with scattering particles quickly ...
  • Hegedus, R.; Lucat, A.; Redon, J.; Pacanowski, R. (The Eurographics Association, 2016)
    Image-based BRDF measurements on spherical material samples present a great opportunity to shorten significantly the acquisition time with respect to more traditional, non-multiplexed measurement methods for isotropic ...
  • Reinhard Klein; Holly Rushmeier (Eurographics Association, 2016)
  • Holzschuch, N.; Pacanowski, R. (The Eurographics Association, 2015)
    There are two different physical models connecting the micro-geometry of a surface and its physical reflectance properties (BRDF). The first, Cook-Torrance, assumes geometrical optics: light is reflected and masked by the ...
  • Weinmann, M.; Klein, R. (The Eurographics Association, 2015)
    The complexity of visual material appearance as observed in the huge variation in material appearance under different viewing and illumination conditions makes material recognition a highly challenging task. In the scope ...
