    • Adaptive Remeshing of Non-Manifold Surfaces 

      Zilske, Michael; Lamecker, Hans; Zachow, Stefan (The Eurographics Association, 2008)
      We present a unified approach for consistent remeshing of arbitrary non-manifold triangle meshes with additional user-defined feature lines, which together form a feature skeleton. Our method is based on local operations ...

      Battiato, Sebastiano; Blasi, Gianpiero Di; Gallo, Giovanni; Guarnera, Giuseppe Claudio; Puglisi, Giovanni (The Eurographics Association, 2008)
      In this paper a novel approach for artificial mosaic generation is proposed. Gradient Vector Flow computation together with heuristics to maximise the covered mosaic area are used. The high frequency details are managed ...

      Fu, Yan; Zhou, Bingfeng (The Eurographics Association, 2008)
      We present a Boolean operation algorithm for free-form solid models represented in geometry images. By taking advantage of the regular data organization of geometry images, our algorithm can perform efficient surface ...

      Duriez, Christian; Courtecuisse, Hadrien; Alcalde, Juan-Pablo de la Plata; Bensoussan, Pierre-Jean (The Eurographics Association, 2008)
      In this paper, we propose a new approach to model interactions through a skinning method. Skinning is a frequently used technique to animate a mesh based on skeleton motion. In the case of a hand motion sequence used to ...
    • Crowds in Context: Evaluating the Perceptual Plausibility of Pedestrian Orientations 

      Peters, Christopher; Ennis, Cathy; McDonnell, Rachel; O'Sullivan, Carol (The Eurographics Association, 2008)
      We describe a work-in-progress evaluating the plausibility of pedestrian orientations. While many studies have focused on creating accurate or fast crowd simulation models for populating virtual cities or other environments, ...
    • Efficient Soft Tissue Modelling Using Charged Particle Control Points 

      Buckley, Oliver; John, Nigel W. (The Eurographics Association, 2008)
      As the performance levels of personal computers increases so does the desire for more realistic and immersive software and simulation. An area where this is particularly the case is that of medical training simulation, ...
    • Efficient Spherical Harmonics Lighting with the Preetham Skylight Model 

      Habel, Ralf; Mustata, Bogdan; Wimmer, Michael (The Eurographics Association, 2008)
      We present a fast and compact representation of a skylight model for spherical harmonics lighting, especially for outdoor scenes. This representation allows dynamically changing the sun position and weather conditions on ...
    • Efficient Visualization of Architectural Models from a Structure and Motion Pipeline 

      Farenzena, Michela; Fusiello, Andrea; Gherardi, Riccardo (The Eurographics Association, 2008)
      State of the art three dimensional reconstruction pipelines can nowadays produce models up to several million polygons without any human intervention from a set of digital images or video. Such models are able to stretch ...
    • Evaluation of a Mobile MR Geovisualisation Interface 

      Liarokapis, Fotis (The Eurographics Association, 2008)
      This paper presents experimental results of a mobile mixed reality interface designed for geovisualization of 3D realistic urban environments which allows dynamic switching between three visualization domains: a virtual ...
    • FMDistance: A Fast and Effective Distance Function for Motion Capture Data 

      Onuma, Kensuke; Faloutsos, Christos; Hodgins, Jessica K. (The Eurographics Association, 2008)
      Given several motion capture sequences, of similar (but not identical) length, what is a good distance function? We want to find similar sequences, to spot outliers, to create clusters, and to visualize the (large) set of ...
    • A Fragile Watermarking Scheme for Authentication of Semi-regular Meshes 

      Wang, Kai; Lavoue, Guillaume; Denis, Florence; Baskurt, Atilla (The Eurographics Association, 2008)
      This paper presents a fragile watermarking scheme for authentication of 3D semi-regular meshes. After one wavelet decomposition, the watermark is inserted by slightly modifying the norms and orientations of the obtained ...
    • Identification of Dynamic Mass Spring Parameters for Deformable Body Simulation 

      Lloyd, Bryn; Kirac, S.; Szekely, Gabor; Harders, Matthias (The Eurographics Association, 2008)
      Mass spring systems (MSS) are frequently used to simulate deformable objects because of their conceptual sim- plicity and computational speed. Unfortunately, the model parameters (spring coefficients, masses) are not related ...
    • Improving Interaction Performance for Ray Tracing 

      Kurz, Daniel; Lux, Christopher; Springer, Jan P.; Froehlich, Bernd (The Eurographics Association, 2008)
      We have developed an approach for improving the performance of object manipulation in ray tracing systems. We assume that users alternate between navigating the scene and manipulating objects in the scene. We divide the ...
    • Interactive Stroke-Based NPR using Hand Postures on Large Displays 

      Grubert, Jens; Carpendale, Sheelagh; Isenberg, Tobias (The Eurographics Association, 2008)
      We explore the use of hand postures to interact with stroke-based rendering (SBR) on touch-sensitive large displays. In contrast to traditional WIMP interfaces, we allow people to directly engage with and influence a ...
