    • Real-Time Volumetric Tests Using Layered Depth Images 

      Trapp, Matthias; Doellner, Juergen (The Eurographics Association, 2008)
      This paper presents a new approach for performing efficiently 3D point-in-volume tests for solid and arbitrary complex shapes. It classifies a 3D point as inside or outside of a solid specified by 3D polygonal geometry. ...
    • Artificial Mosaics by Gradient Vector Flow 

      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 ...
    • Measuring and Enhancing the Legibility of GPU-rendered Text 

      Tycowicz, Christoph von; Loviscach, Joern (The Eurographics Association, 2008)
      Whereas the rendering of tiny typefaces in 2D applications has been perfected over decades, the legibility of text in 3D visualizations has rarely been addressed. This affects road signs, meters, screens, and books in ...
    • 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 ...
    • A Novel Approach to Support Quality of Experience in Remote Visualization on Mobile Devices 

      Paravati, Gianluca; Sanna, Andrea; Lamberti, Fabrizio; Ciminiera, Luigi (The Eurographics Association, 2008)
      This paper proposes a novel approach to support Quality of Experience (QoE) in remote visualization on mobile devices. Image resolution, frame rate, compression ratio, color depth, and device throughput are simultaneously ...
    • 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, ...
    • 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 ...
    • Post Facto Registration Tools for Urban Modelling 

      Morvan, Yann; Hinks, Tommy; Carr, Hamish; Laefer, Debra F.; O'Sullivan, Carol; Morrish, W. Sean (The Eurographics Association, 2008)
      Urban modelling applications require high-precision geometric models both for graphical rendering and for engineering purposes. While geometric models, photographic images and laser-scanned point clouds are ideally ...
    • Physically-Based Interactive Sand Simulation 

      Pla-Castells, Marta; García-Fernandez, Ignacio; Martinez-Dura, Rafael J. (The Eurographics Association, 2008)
      The interactive simulation of 3D terrains has been approached from several perspectives. Due to the complexity of the system involved, most of the models proposed focus on a visually realistic animation of the scene, rather ...
    • Physically Based Modeling of Ice with Bubbles 

      Madrazo, Carlos; Okada, Minoru (The Eurographics Association, 2008)
      Bubbles are an important characteristic that determine the appearance of ice. In this paper the authors propose a strategy in order to construct geometric representations of ice that integrates bubbles in an ice cube and ...
    • 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 ...
    • 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, ...
    • 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 ...
    • Boolean Operations for Free-form Models Represented in Geometry Images 

      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 ...
