    • 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 ...
