      Dobashi, Yoshinori; Matsuda, Yasuhiro; Yamamoto, Tsuyoshi; Nishita, Tomoyuki (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Recently, many techniques using computational fluid dynamics have been proposed for the simulation of natural phenomena such as smoke and fire. Traditionally, a single grid is used for computing the motion of fluids. When ...
    • Rendering Method for Flat Origami 

      Mitani, Jun (The Eurographics Association, 2008)
      In flat Origami (Origami which is folded flat), some cases exist that have a closed-loop in the overlap order of faces after they are folded. It is difficult to display this shape correctly on the screen when Origami is ...

      The area of illustrative visualization is concerned with developing methods to enhance the depiction of scientific data based on principles founded in traditional illustration. The illustration community has century-long ...
    • The Role of Perception for Computer Graphics 

      Bartz, Dirk; Cunningham, Douglas; Fischer, Jan; Wallraven, Christian (The Eurographics Association, 2008)
      Traditionally, computer graphics strived to achieve the technically best representation of the scenario or scene. For rendering, this lead to the preeminence of representations based on the physics of light interacting ...
    • Texture Synthesis From Photographs 

      Eisenacher, C.; Lefebvre, S.; Stamminger, M. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      The goal of texture synthesis is to generate an arbitrarily large high-quality texture from a small input sample. Generally, it is assumed that the input image is given as a flat, square piece of texture, thus it has to ...
    • CHC++: Coherent Hierarchical Culling Revisited 

      Mattausch, Oliver; Bittner, Jiri; Wimmer, Michael (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a new algorithm for efficient occlusion culling using hardware occlusion queries. The algorithm significantly improves on previous techniques by making better use of temporal and spatial coherence of visibility. ...
    • The Shadow Meets the Mask: Pyramid-Based Shadow Removal 

      Shor, Yael; Lischinski, Dani (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      In this paper we propose a novel method for detecting and removing shadows from a single image thereby obtaining a high-quality shadow-free image. With minimal user assistance, we first identify shadowed and lit areas on ...
    • Distortion-Free Steganography for Polygonal Meshes 

      Bogomjakov, Alexander; Gotsman, Craig; Isenburg, Martin (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a technique for steganography in polygonal meshes. Our method hides a message in the indexed rep-resentation of a mesh by permuting the order in which faces and vertices are stored. The permutation is relative ...
    • An Example-based Procedural System for Element Arrangement 

      Ijiri, Takashi; Mech, Radomir; Igarashi, Takeo; Miller, Gavin (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      We present a method for synthesizing two dimensional (2D) element arrangements from an example. The main idea is to combine texture synthesis techniques based-on a local neighborhood comparison and procedural modeling ...
    • Computer Graphics Curriculum: a Programming Approach 

      Sobczyk, Dominique; Touzeau, Marie-Solange; Bourdin, Jean-Jacques (The Eurographics Association, 2008)
      At University Paris 8 the computer science curriculum is focused on programming as a good technique to improve the skills of students and to improve the success of studies. It has been reinforced when France adopted the ...
    • Image-based Shaving 

      Nguyen, Minh Hoai; Lalonde, Jean-Francois; Efros, Alexei A.; De la Torre, Fernando (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Many categories of objects, such as human faces, can be naturally viewed as a composition of several different layers. For example, a bearded face with glasses can be decomposed into three layers: a layer for glasses, a ...
    • Image-based Aging Using Evolutionary Computing 

      Hubball, Daniel; Chen, Min; Grant, Phil W. (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Aging has considerable visual effects on the human face and is difficult to simulate using a universally-applicable global model. In this paper, we focus on the hypothesis that the patterns of age progression (and regression) ...
    • Knitty: 3D Modeling of Knitted Animals with a Production Assistant Interface 

      Igarashi, Yuki; Igarashi, Takeo; Suzuki, Hiromasa (The Eurographics Association, 2008)
      Knitty is an interactive design system for creating knitted animals. The user designs a 3D surface model using a sketching interface. The system automatically generates a knitting pattern and then visualizes the shape of ...
    • Visualizing Underwater Ocean Optics 

      Gutierrez, Diego; Seron, Francisco J.; Munoz, Adolfo; Anson, Oscar (The Eurographics Association and Blackwell Publishing Ltd, 2008)
      Simulating the in-water ocean light field is a daunting task. Ocean waters are one of the richest participating media, where light interacts not only with water molecules, but with suspended particles and organic matter ...
