  • Towards a Principled Kernel Prediction for Spatially Varying BSSRDFs 

    Elek, Oskar; Krivánek, Jaroslav (The Eurographics Association, 2018)
    While the modeling of sub-surface translucency using homogeneous BSSRDFs is an established industry standard, applying the same approach to heterogeneous materials is predominantly heuristical. We propose a more principled ...

    Alejandre, Adrian; Aliaga, Carlos; Marco, Julio; Jarabo, Adrian; Muñoz, Adolfo (The Eurographics Association, 2018)
    Accurate representation of realistic cloth appearance is of high importance in many industry fields such as entertainment and textile design. However, microstructure of fibers and their optical properties generate very ...
  • Image-based Fitting of Procedural Yarn Models 

    Saalfeld, Alina; Reibold, Florian; Dachsbacher, Carsten (The Eurographics Association, 2018)
    While common in real life, rendering fiber and cloth accurately is challenging. Recent fiber-based, procedural rendering approaches proved to be able to capture a great amount of details of real yarn. However, the current ...
  • Iso Photographic Rendering 

    Porral, Philippe; Lucas, Laurent; Muller, Thomas; Randrianandrasana, Joël (The Eurographics Association, 2018)
    In the field of computer graphics, the simulation of the visual appearance of materials requires an accurate computation of the light transport equation. Consequently, material models need to take into account various ...
  • A Simple Diffuse Fluorescent BBRRDF Model 

    Jung, Alisa; Hanika, Johannes; Marschner, Steve; Dachsbacher, Carsten (The Eurographics Association, 2018)
    Fluorescence - the effect of a photon being absorbed at one wavelength and re-emitted at another - is present in many common materials such as clothes and paper. Yet there has been little research in rendering or modeling ...
  • On the Advancement of BTF Measurement on Site 

    Havran, Vlastimil; Hosek, Jan; Nemcova, Sarka; Cap, Jiri (The Eurographics Association, 2018)
    We present our progress to the on-site measurement of the spatially varying surface reflectance represented by bidirectional texture function (BTF). This requires a physical realization of a portable instrument that can ...
  • ICL Multispectral Light Stage: Building a Versatile LED Sphere with Off-the-shelf Components 

    Kampouris, Christos; Ghosh, Abhijeet (The Eurographics Association, 2018)
    We describe the design and implementation of a versatile multispectral light stage (LED sphere) consisting of 168 RGB and color temperature controllable white (W+) lamps, respectively. The light stage is powered with two ...
  • Frontmatter: Eurographics 2018 Workshop on Material Appearance Modeling 

    Klein, Reinhard; Rushmeier, Holly (The Eurographics Association, 2018)
  • Experimental Analysis of BSDF Models 

    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 ...
  • Diffraction Prediction in HDR Measurements 

    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 ...
  • The Effects of Digital Cameras Optics and Electronics for Material Acquisition 

    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 ...
  • Challenges in Appearance Capture and Predictive Modeling of Textile Materials 

    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 ...
  • Towards Sparse and Multiplexed Acquisition of Material BTFs 

    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 ...
  • High-Quality Multi-Spectral Reflectance Acquisition with X-Rite TAC7 

    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 ...
