      We propose discussing the performance of appearance modeling in terms of supported material and illumination gamut. While we have a precise understanding of the cost of any given appearance modeling method, performance is ...
    • BTF-based Material Representations: Current Challenges 

      Ruiters, R.; Klein, R. (The Eurographics Association, 2013)
      The development of Bidirectional Texture Functions (BTFs) has made it possible for a wide range of different materials to acquire their characteristic appearance from a real-world counterpart and reproduce it faithfully ...

      Schroeder, K.; Zincke, A. (The Eurographics Association, 2013)
      In this position paper, we discuss the usability of different material representations for interactive appearance design in the context of visual prototyping. We emphasize the importance of methods explicitly considering ...
    • From Color to Appearance in the Real World 

      Ellens, M.; Mueller, G.; Lamy, F. (The Eurographics Association, 2013)
      X-Rite's declared ambition is to create a digital ecosystem for appearance; a daunting challenge that has many dimensions and has not been accomplished so far. In this short paper we sketch a path from color to full ...

      Schregle, R.; Denk, C.; Slusallek, P.; Glencross, M. (The Eurographics Association, 2013)
      Material reflectance definitions are core to high fidelity visual simulation of objects within a compelling 3D scene. In the automotive industry these are used across the entire business process: from conceptualisation of ...
    • DOME II: A Parallelized BTF Acquisition System 

      Schwartz, C.; Sarlette, R.; Weinmann, M.; Klein, R. (The Eurographics Association, 2013)
      Bidirectional Texture Functions (BTFs) provide a realistic depiction of the appearance of many real-world materials as they contain the spatially varying light scattering behavior of the material surface. Since editing of ...
    • 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 ...
    • 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 ...
    • The Role of Visual Comparison Testing in Material Appearance Modeling 

      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. ...
    • Statistical Characterization of Surface Reflectance 

      Havran, Vlastimil; Sbert, Mateu (The Eurographics Association, 2014)
      The classification of surface reflectance functions as diffuse, specular, and glossy has been introduced by Heckbert more than two decades ago. Many rendering algorithms are dependent on such a classification, as different ...
    • ALTA: A BRDF Analysis Library 

      Belcour, Laurent; Barla, Pascal; Pacanowski, Romain (The Eurographics Association, 2014)
      In this document, we introduce ALTA, a cross platform generic open-source library for Bidirectional Reflectance Distribution Function (BRDF) analysis. Among others, ALTA permits to estimate BRDF models parameters from ...
    • 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 ...
    • Scanning Gonio-Photometers for Asymmetric Acquisition of Fine-structured BSDF 

      Apian-Bennewitz, Peter (The Eurographics Association, 2014)
      Results of building and running out-of-plane scanning gonio-photometers for a number of years and projects are presented. Key concepts are a fast drive system and adaptive scan pattern to sample peaks at higher angular ...
    • Reducing Anisotropic BSDF Measurement to Common Practice 

      Ward, Greg; Kurt, Murat; Bonneel, Nicolas (The Eurographics Association, 2014)
      We address the problem of measuring and representing reflection and transmission for anisotropic materials without relying on mathematical models or a large sample database. By eliminating assumptions of material behavior, ...
