    • Adaptive Texture Space Shading for Stochastic Rendering 

      Andersson, Magnus; Hasselgren, Jon; Toth, Robert; Akenine-Möller, Tomas (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      When rendering effects such as motion blur and defocus blur, shading can become very expensive if done in a naïve way, i.e. shading each visibility sample. To improve performance, previous work often decouple shading from ...
    • Analogy-Driven 3D Style Transfer 

      Ma, Chongyang; Huang, Haibin; Sheffer, Alla; Kalogerakis, Evangelos; Wang, Rui (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Style transfer aims to apply the style of an exemplar model to a target one, while retaining the target s structure. The main challenge in this process is to algorithmically distinguish style from structure, a high-level, ...
    • Art-Photographic Detail Enhancement

      We present a novel method for enhancing details in a digital photograph, inspired by the principle of art photography. In contrast to the previous methods that primarily rely on tone scaling, our technique provides a ...
    • Automatic Generation of Tourist Brochures 

      Birsak, Michael; Musialski, Przemyslaw; Wonka, Peter; Wimmer, Michael (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We present a novel framework for the automatic generation of tourist brochures that include routing instructions and additional information presented in the form of so-called detail lenses. The first contribution of this ...
    • Clean Color: Improving Multi-filament 3D Prints 

      Hergel, Jean; Lefebvre, Sylvain (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Fused Filament Fabrication is an additive manufacturing process by which a 3D object is created from plastic filament. The filament is pushed through a hot nozzle where it melts. The nozzle deposits plastic layer after ...
    • Coded Exposure HDR Light-Field Video Recording 

      Schedl, David C.; Birklbauer, Clemens; Bimber, Oliver (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Capturing exposure sequences to compute high dynamic range (HDR) images causes motion blur in cases of camera movement. This also applies to light-field cameras: frames rendered from multiple blurred HDR lightfield ...
    • Compressing Dynamic Meshes with Geometric Laplacians 

      Vasa, Libor; Marras, Stefano; Hormann, Kai; Brunnett, Guido (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      This paper addresses the problem of representing dynamic 3D meshes in a compact way, so that they can be stored and transmitted efficiently. We focus on sequences of triangle meshes with shared connectivity, avoiding the ...
    • Content-Aware Surface Parameterization for Interactive Restoration of Historical Documents 

      Pal, Kazim; Schüller, Christian; Panozzo, Daniele; Sorkine-Hornung, Olga; Weyrich, Tim (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We present an interactive method to restore severely damaged historical parchments. When damaged by heat in a fire, such manuscripts undergo a complex deformation and contain various geometric distortions such as wrinkling, ...
    • Crack-free Rendering of Dynamically Tesselated B-Rep Models 

      Claux, Frédéric; Barthe, Loïc; Vanderhaeghe, David; Jessel, Jean-Pierre; Paulin, Mathias (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We propose a versatile pipeline to render B-Rep models interactively, precisely and without rendering-related artifacts such as cracks. Our rendering method is based on dynamic surface evaluation using both tesselation and ...
    • Crowd Sculpting: A Space-time Sculpting Method for Populating Virtual Environments 

      Jordao, Kevin; Pettré, Julien; Christie, Marc; Cani, Marie-Paule (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      We introduce "Crowd Sculpting": a method to interactively design populated environments by using intuitive deformation gestures to drive both the spatial coverage and the temporal sequencing of a crowd motion. Our approach ...
    • Deformation with Enforced Metrics on Length, Area and Volume 

      Jin, Shuo; Zhang, Yunbo; Wang, Charlie C. L. (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      Techniques have been developed to deform a mesh with multiple types of constraints. One limitation of prior methods is that the accuracy of demanded metrics on the resultant model cannot be guaranteed. Adding metrics ...
