  • 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 ...

  • 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 ...
  • Nielsen, J. B.; Eiriksson, E. R.; Kristensen, R. L.; Wilm, J.; Frisvad, J. R.; Conradsen, K.; Aanæs, H. (The Eurographics Association, 2015)
    In this positional paper, we discuss the potential benefits of using appearance models in additive manufacturing, metal casting, wind turbine blade production, and 3D content acquisition. Current state of the art in ...
  • Havran, V. (The Eurographics Association, 2015)
    The accurate BTF data representation requires specialized measurement gantries, some of them designed as gonireflectometers. These consist of an illumination source and a camera mounted on two robotic arms, one degree of ...
  • Brok, D. den; Weinmann, M.; Klein, R. (The Eurographics Association, 2015)
    Due to the richness of real-world materials, arguably one of the biggest challenges in rendering is to come up with models that describe their appearance well. The image-based bidirectional texture function (BTF) is known ...
  • Barla, P.; Belcour, L.; Pacanowski, R. (The Eurographics Association, 2015)
    In this paper, we extend the work of Neumann et al. [NNSK99] and Stark et al. [SAS05] to a pair of 4D BRDF parameterizations with explicit changes of variables. We detail their mathematical properties and relationships to ...
  • Mueller, Gero; Lamy, Francis (The Eurographics Association, 2015)
    In this short paper X-Rite proposes a new file format for exchanging digital material appearance. The format is a vital part of X-Rite's appearance initiative consisting of a new generation of appearance capturing devices ...
  • Kettner, L.; Raab, M.; Seibert, D.; Jordan, J.; Keller, A. (The Eurographics Association, 2015)
    We introduce the physically-based Material Definition Language (MDL). Based on the principle of strictly separating material definition and rendering algorithms, each MDL material is applicable across different rendering ...

  • Rushmeier, Holly (The Eurographics Association, 2014)
    Modeling the material appearance of physical materials requires access to the materials. Sets of identical physical material models were prepared for distribution at the workshop on material appearance modeling 2014 ...
  • Jakob, Wenzel (The Eurographics Association, 2014)
    In this talk, I will give an overview of one-dimensional Linear Transport Theory, which concerns itself with the study of random scattering and absorption processes and the inference of large-scale behavior from simple ...
  • Meyer, Gary (The Eurographics Association, 2014)
    Material appearance modeling should involve end user testing. These tests can be visual comparison experiments where decisions made with real physical samples are compared with choices done using computer graphic simulations. ...
