      Characters are of paramount importance in computer graphics since they enrich 3D worlds with immersion and life, and extend the range of possible applications. They are also very complex objects to manage due to their ...
    • Spectral Methods for Mesh Processing and Analysis 

      Zhang, Hao; Kaick, Oliver van; Dyer, Ramsay (The Eurographics Association, 2007)
      Spectral methods for mesh processing and analysis rely on the eigenvalues, eigenvectors, or eigenspace projections derived from appropriately defined mesh operators to carry out desired tasks. Early works in this area can ...

      We present a novel software assistant that unlocks new potentials in neurosurgical planning and risk assessment. It allows surgeons to approach the task in an intuitive manner, by providing them with the possibility to ...
    • Virtual Agent Navigation in Open Spaces using Iterative Shrinking Polygons 

      Haciomeroglu, Murat; Laycock, Robert; Day, Andy (The Eurographics Association, 2007)
      Populating an urban environment with a virtual crowd provides a dynamic element to an otherwise static scene; bringing the virtual environment to life. One of the fundamental components governing the fidelity of the scene ...
    • Take a Stroll in Another World 

      Ruttkay, Zsofia; Orbons, Erik (The Eurographics Association, 2007)
      Another World II is a print by the famous Dutch artist M. C. Escher, depicting a cube with arch-like openings on each side. What makes the print interesting is that the depicted views in the arches are inconsistent, leaving ...
    • Spinoff - Transferring Energy between Real and Virtual Worlds 

      Groenegress, Christoph; Slater, Mel; Tamke, Martin; Thomsen, Mette Ramsgard (The Eurographics Association, 2007)
      There is a widening gap between interaction devices for Virtual Environments and other factors such as graphical realism, accessibility and complexity. To address this problem, we developed a Mixed Reality environment that ...
    • Bridging Semantic Web and Digital Shapes 

      Papaleo, Laura; Floriani, Leila De; Hendler, Jim (The Eurographics Association, 2007)
      Since the volume of multimedia content available on the Web is continuously increasing, a clear need for advanced techniques capable of performing an effective retrieval and management of such data. In this context, in ...
    • Pareto-Based Perceptual Metric for Imperceptible Simplification on Mobile Displays 

      Wu, Fan; Agu, Emmanuel; Lindsay, Clifford (The Eurographics Association, 2007)
      Graphics on mobile devices has become popular because untethered computing is convenient and increases pro- ductivity. Mobile displays come in different resolutions that affect the scene Level-of-Detail (LoD) that users ...
    • Real-Time 3D Lettering with a 2D Font Engine 

      Heise, Sebastian; Loviscach, Jörn (The Eurographics Association, 2007)
      Standard texturing shows a number of problems with 3D objects such as road signs, labels, or books. If letters are displayed at too large a scale, textures show blurred instead of hard edges; if letters are displayed at ...
    • Fast Hierarchical 3D Distance Transforms on the GPU 

      Cuntz, Nicolas; Kolb, Andreas (The Eurographics Association, 2007)
      This paper describes a fast approximate approach for the GPU-based computation of 3D Euclidean distance transforms (DT), i.e. distance fields with associated vector information to the closest object point. Our hierarchical ...
    • Liquid Diffusion Model that Accounts for a Variety of Dyeing Parameters 

      Yuki, Morimoto; Tanaka, Masayuki; Tsuruno, Reiji; Tomimatsu, Kiyoshi (The Eurographics Association, 2007)
      This paper describes a method for simulating and visualizing dyeing based on weave patterns and the physical parameters of the threads and the dye. We apply Fick s second law with a variable diffusion coefficient, which ...
    • Painterly Effects Rendering with Focus Based Level of Detail 

      Levente, Kovács; Tamás, Szirányi (The Eurographics Association, 2007)
      We present a novel method for automatically creating scalable and portable 2D non-photorealistically rendered (NPR) images with painterly effects, with level of detail control. The novelty of the approach lies both in using ...
