    • Linear Models for Material BTFs and Possible Applications 

      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 ...
    • Linear Transport Theory and Applications to Rendering 

      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 ...

    • MAM 2019: Frontmatter 

      Klein, Reinhard; Rushmeier, Holly (Eurographics Association, 2019)
    • The MAM2014 Sample Set 

      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 ...
    • The Material Definition Language 

      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 ...
    • Material Modeling with Physical Constraints 

      Weidlich, A.; Meseth, J. (The Eurographics Association, 2013)
      The workflows and interfaces of commercial rendering software are currently designed for believable rendering purposes. However, for predictive rendering other approaches are needed; for example, the usual approach to ...
    • A Method for Fitting Measured Car Paints to a Game Engine's Rendering Model 

      Kneiphof, Tom; Golla, Tim; Weinmann, Michael; Klein, Reinhard (The Eurographics Association, 2018)
      Car paints are visually complex materials that are of great importance for numerous real-time applications, including not only the game and movie industries but also virtual prototyping and design as well as advertisement. ...
    • Neural Appearance Synthesis and Transfer 

      Mazlov, Ilya; Merzbach, Sebastian; Trunz, Elena; Klein, Reinhard (The Eurographics Association, 2019)
      Appearance acquisition is a challenging problem. Existing approaches require expensive hardware and acquisition times are long. Alternative ''in-the-wild'' few-shot approaches provide a limited reconstruction quality. ...
    • 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 ...
    • On the Nature of Perceptual Translucency 

      Gigilashvili, Davit; Thomas, Jean-Baptiste; Hardeberg, Jon Yngve; Pedersen, Marius (The Eurographics Association, 2020)
      Translucency is an appearance attribute used to characterize materials with some degree of subsurface light transport. Although translucency as a radiative transfer inside the medium is relatively well understood, translucency ...
    • On Visual Attractiveness of Anisotropic Effect Coatings 

      Filip, Jiří; Kolafová, Martina (The Eurographics Association, 2019)
      With the global trend in customer preference towards achromatic car colors, color designers in coating industry strive to create novel design-critical appearances based on novel effect pigments. At microscopic scale, the ...
    • Perception of Car Shape Orientation and Anisotropy Alignment 

      Filip, Jiri; Kolafová, Martina (The Eurographics Association, 2018)
      The color designers are used to introduce customized product design, visually communicating the unique impression of a car. They always carefully observe harmony of color and body shape to obtain desired visual impression. ...
    • Practical Experiences with Using Autocollimator for Surface Reflectance Measurement 

      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 ...
