      Leifman, George; Tal, Ayellet (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      This paper proposes a novel algorithm for colorization of meshes. This is important for applications in which the model needs to be colored by just a handful of colors or when no relevant image exists for texturing the ...
    • Procedural Texture Preview 

      Lasram, Anass; Lefebvre, Sylvain; Damez, Cyrille (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      Procedural textures usually require spending time testing parameters to realize the diversity of appearances. This paper introduces the idea of a procedural texture preview: A single static image summarizing in a limited ...
    • Rasterized Bounding Volume Hierarchies 

      Novák, Jan; Dachsbacher, Carsten (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      We present the rasterized bounding volume hierarchy (RBVH), a compact data structure that accelerates approximate ray casting of complex meshes and provides adjustable level of detail. During construction, we identify ...
    • A GPU-based Approach for Massive Model Rendering with Frame-to-Frame Coherence 

      Peng, Chao; Cao, Yong (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      Rendering massive 3D models in real-time has long been recognized as a very challenging problem because of the limited computational power and memory space available in a workstation. Most existing rendering techniques, ...
    • Interactive Editing of GigaSample Terrain Fields 

      Treib, Marc; Reichl, Florian; Auer, Stefan; Westermann, Rüdiger (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      Previous terrain rendering approaches have addressed the aspect of data compression and fast decoding for rendering, but applications where the terrain is repeatedly modified and needs to be buffered on disk have not been ...
    • Black is Green: Adaptive Color Transformation For Reduced Ink Usage 

      Shapira, Lior; Oicherman, Boris (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      A vast majority of color transformations applied to an image in the digital press industry are static and precalculated. In order to achieve the best quality on a wide variety of different images, these transformations ...
    • Real-time Realistic Rendering and Lighting of Forests 

      Bruneton, Eric; Neyret, Fabrice (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      Realistic real-time rendering and lighting of forests is an important aspect for simulators and video games. This is a difficult problem, due to the massive amount of geometry: aerial forest views display millions of trees ...
    • SMAA: Enhanced Subpixel Morphological Antialiasing 

      Jimenez, Jorge; Echevarria, Jose I.; Sousa, Tiago; Gutierrez, Diego (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      We present a new image-based, post-processing antialiasing technique, which offers practical solutions to the common, open problems of existing filter-based real-time antialiasing algorithms. Some of the new features include ...
    • SimpleFlow: A Non-iterative, Sublinear Optical Flow Algorithm 

      Tao, Michael; Bai, Jiamin; Kohli, Pushmeet; Paris, Sylvain (The Eurographics Association and John Wiley and Sons Ltd., 2012)
      Optical flow is a critical component of video editing applications, e.g. for tasks such as object tracking, segmentation, and selection. In this paper, we propose an optical flow algorithm called SimpleFlow whose running ...
