    • 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 ...

      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 ...

    • 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 ...

    • Laziness is a Virtue: Motion Stitching Using Effort Minimization 

      Li, Lei; McCann, James; Faloutsos, Christos; Pollard, Nancy (The Eurographics Association, 2008)
      Given two motion-capture sequences that are to be stitched together, how can we assess the goodness of the stitching? The straightforward solution, Euclidean distance, permits counter-intuitive results because it ignores ...

    • Level of Detail Flow Simulation 

      Klar, Gergely (The Eurographics Association, 2008)
      In this paper we present a framework to simulate visually plausible large scale flow of fluids or smoke. To maintain real-time speed, we define the simulation over a coarse grid which is refined with a more detailed grid ...

    • 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 ...

    • Microquad Soft Shadow Mapping Revisited 

      Schwarz, Michael; Stamminger, Marc (The Eurographics Association, 2008)
      Recently, real-time soft shadow research saw many important contributions from the class of soft shadow mapping algorithms, where approximate occluder geometry is reconstructed from a shadow map and backprojected onto the ...

      Meng, Jingjing; Yuan, Junsong; Hans, Mat; Wu, Ying (The Eurographics Association, 2008)
      Mining frequently occurring temporal motion patterns (motion motifs) is important for understanding, organizing and retrieving motion data. However, without any a priori knowledge of the motifs, such as their lengths, ...
