      This paper presents a novel approach towards training with game elements in an interactive environment by means of OpenCrimeScene, a virtual 3D training system for crime scene investigation (CSI). The application is designed ...

    • Generation and Tessellation of Tree Stems 

      Skjermo, Jo (The Eurographics Association, 2008)
      When visualizing tree stems and branches for use in interactive applications, the polygon models resolution are usually as low as possible to achieve a high frame rate. Also, to ease animation and mesh generation, each ...

    • GPU-based Visualisation of Protein Secondary Structure 

      Krone, Michael; Bidmon, Katrin; Ertl, Thomas (The Eurographics Association, 2008)
      The increasing number of protein 3D structure information available makes the high-quality visualisation of this information play a more and more important role. Beside element-based representations the secondary-structurebased ...

    • Grammatical Evolution for Gait Retargeting 

      Murphy, James E.; Carr, Hamish; O'Neill, Michael (The Eurographics Association, 2008)
      Artists and scientists require tools to construct physics-based animal models. However, animating these models requires motion data for realistic movement. Motion data may either be measured from real-life animals-in-motion ...

    • A Haptic Rendering Algorithm for Drilling into Volume Data 

      Liu, Yu; Laycock, S. D. (The Eurographics Association, 2008)
      With the developments of volume visualisation technology for complex data sets comes new challenges in terms of user interaction and information extraction. Volume haptics has proven itself to be an effective way of ...

    • Image Abstraction by Structure Adaptive Filtering 

      Kyprianidis, Jan Eric; Döllner, Jürgen (The Eurographics Association, 2008)
      In this work we present a framework of automatic non-photorealistic image processing techniques that create simplified stylistic illustrations from color images, videos and 3D renderings. To smooth low-contrast regions ...

    • Interactive Grid Based Binning for Information Visualization 

      Longshaw, S. M.; Turner, M. J.; Hewitt, W. T. (The Eurographics Association, 2008)
      Clutter within information visualization (infovis) systems is an area of continuing concern and is receiving increasing research interest. Solutions to the problem vary in their approach, ranging from novel visualizations ...
