    • Generation of Folded Terrains from Simple Vector Maps 

      Michel, Elie; Emilien, Arnaud; Cani, Marie-Paule (The Eurographics Association, 2015)
      While several terrain generation methods focused on plausible watersheds, the fact that most mountains should not be isolated but rather be part of wider scale mountain ranges was seldom considered. In this work, we present ...
    • Separation of Manga Line Drawings and Screentones 

      Ito, Kota; Matsui, Yusuke; Yamasaki, Toshihiko; Aizawa, Kiyoharu (The Eurographics Association, 2015)
      Screentones are unique expressions of Japanese comics (manga), which enrich their visual expression. However, such screentones have a very different visual nature from that of line drawing areas; this prevents us from ...
    • Improving k-buffer Methods via Occupancy Maps 

      Vasilakis, Andreas A.; Papaioannou, Georgios (The Eurographics Association, 2015)
      In this work, we investigate an efficient approach to treat fragment racing when computing k-nearest fragments. Based on the observation that knowing the depth position of the k-th fragment we can optimally find the k-closest ...
    • Adaptive LightSlice for Virtual Ray Lights 

      Frederickx, Roald; Bartels, Pieterjan; Dutré, Philip (The Eurographics Association, 2015)
      We speed up the rendering of participating media with Virtual Ray Lights (VRLs) by clustering them in a preprocessing step. A subset of representative VRLs is then sampled from the clustering, which is used for the final ...
    • Interactive Pixel-Accurate Rendering of LR-Splines and T-Splines 

      Hjelmervik, Jon M.; Fuchs, Franz G. (The Eurographics Association, 2015)
      Flexible surface types on irregular grids, such as T-splines and LR-splines, are gaining popularity in science and industry due to the possibility for local grid refinement. We present a novel rendering algorithm for those ...
    • High-Quality Shadows for Streaming Terrain Rendering 

      Chajdas, Matthäus G.; Reichl, Florian; Dick, Christian; Westermann, Rüdiger (The Eurographics Association, 2015)
      Rendering of large, detailed 3D terrains on commodity hardware has become possible through the use of raycasting, data caching and prefetching. Adding dynamic shadows as they appear during a day-night cycle remais a challenge ...
    • Pixel Merge Unit 

      Sathe, Rahul; Akenine-Möller, Tomas (The Eurographics Association, 2015)
      Multi-sample anti-aliasing is a popular technique for reducing geometric aliasing (jagged edges) and is supported in all modern graphics processors. With multi-sampling anti-aliasing, visibility and depth are sampled more ...
    • An Interactive Editing System for Visual Appearances of Fire and Explosions 

      Dobashi, Yoshinori; Shibukawa, Yuhei; Tada, Munehiro; Sato, Syuhei; Iwasaki, Kei; Yamamoto, Tsuyoshi (The Eurographics Association, 2015)
      Synthetic volumetric fire and explosions are important visual effects used in many applications such as computer games and movies. For these applications, artists are often requested to achieve the desired visual appearance ...
    • Target Temperature Driven Dynamic Flame Animation 

      Cui, Qiaodong; Wu, Zhaohui; Xing, Chang; Zhou, Zhong; Wu, Wei (The Eurographics Association, 2015)
      Fire/flame plays an important role in virtual environment. Controlling the flame behavior in an intuitive yet precise manner remains a challenging open problem. In this paper, a target temperature driven simulation method ...
    • Individual Time Stepping for SPH Fluids 

      He, Liangliang; Ban, Xiaojuan; Liu, Xu; Wang, Xiaokun (The Eurographics Association, 2015)
      We present a novel adaptive stepping scheme for SPH fluids, in which particles have their own time-steps determined from local conditions, e.g. Courant condition. These individual time-steps are constrained for global ...
    • Eye-tracktive: Measuring Attention to Body Parts when Judging Human Motions 

      Ennis, Cathy; Hoyet, Ludovic; O'Sullivan, Carol (The Eurographics Association, 2015)
      Virtual humans are often endowed with human-like characteristics to make them more appealing and engaging. Motion capture is a reliable way to represent natural motion on such characters, thereby allowing a wide range of ...
    • Interactive HDR Environment Map Capturing on Mobile Devices 

      Kán, Peter (The Eurographics Association, 2015)
      Real world illumination, captured by digitizing devices, is beneficial to solve many problems in computer graphics. Therefore, practical methods for capturing this illumination are of high interest. In this paper, we present ...
    • Sketch-Based Controllers for Blendshape Facial Animation 

      Cetinaslan, Ozan; Orvalho, Verónica; Lewis, John (The Eurographics Association, 2015)
      The blendshape approach is a widely used technique to generate realistic facial animation. However, creating blendshape facial animations using traditional weight editing tools requires either memorizing the function of a ...
    • Content-Aware Projection for Tiny Planets 

      Brown, Matthew (The Eurographics Association, 2015)
      Tiny Planets visualise the world looking down at the ground, with physically unrealisable projections that curve the ground plane to look like small worlds. Whilst certain geometries, such as Stereographic, are known to ...
    • Fractured Object Reassembly via Robust Surface Registration 

      Mavridis, Pavlos; Andreadis, Anthousis; Papaioannou, Georgios (The Eurographics Association, 2015)
      The reassembly of fractured 3D objects from their parts is an important problem in cultural heritage and other domains.We approach reassembly from a geometric matching perspective and propose a pipeline for the automatic ...
