    • Aesthetic-Interaction: Exploring the Importance of the Visual Aesthetic in the Creation of Engaging Photorealistic VR Environments 

      Carroll, Fiona (The Eurographics Association, 2009)
      Nearly forty years since its conception, the medium of VR is still an enigma. In many ways, it is a medium that still lacks its own uniform language. VR, and particularly photorealistic VR, is a medium that is so occupied ...
    • An Aliasing Theory of Shadow Mapping 

      Zhang, Fan; Zhao, Chong; Sun, Hanqiu (The Eurographics Association, 2009)
      Shadow mapping is a popular image-based technique for real-time shadow rendering. Although numerous improvements have been made to help anti-aliasing in shadow mapping, there is a lack of mathematical tools that allow us ...
    • Automatically Generating Virtual Humans using Evolutionary Algorithms 

      Albin-Clark, Adrian; Howard, Toby (The Eurographics Association, 2009)
      Abstract Virtual Humans are used in many applications either as an embodiment of a real person (an "avatar"), or under the control of a computer program (an "agent" or "non-player character"). The automatic generation of ...
    • Calibrating a COTS Monitor to DICOM Standard 

      Grimstead, Ian J.; Avis, Nick J. (The Eurographics Association, 2009)
      Abstract We present a method for calibrating a commodity, off-the-shelf (COTS) monitor (costing in the region of £200) to produce a greyscale image approximately calibrated to the DICOM standard, rather than require a ...
    • Coastal Shelf Visualization using VTK and OpenDX of Hydro-Informatic Numerical Models 

      George, Richard L. S. F.; Roberts, Jonathan C. (The Eurographics Association, 2009)
      Scientific visualization has an important role in climate change analysis, especially by creating dynamic interactive environments. The earth sciences, such as oceanography, utilize many numerical models; experts wish to ...
    • Design and Evaluation of a Hardware Accelerated Ray Tracing Data Structure 

      Steffen, Michael; Zambreno, Joseph (The Eurographics Association, 2009)
      The increase in graphics card performance and processor core count has allowed significant performance accel- eration for ray tracing applications. Future graphics architectures are expected to continue increasing the ...
    • Developing an Application to Provide Interactive Threedimensional Visualisation of Bone Fractures 

      Wilson, Arline F.; Musgrove, Peter B.; Buckley, Kevan A.; Pearce, Gill; Geoghegan, John (The Eurographics Association, 2009)
      The main research question for this work is: What are the factors involved in developing a three-dimensional (3D) interactive model of a bone fracture and how best may these be addressed? This paper presents work in progress ...
    • Diffusion and Fractional Diffusion Based Image Processing 

      Blackledge, Jonathan Michael (The Eurographics Association, 2009)
      We consider the background to describing strong scattering in terms of diffusive processes based on the diffusion equation. Intermediate strength scattering is then considered in terms of a fractional diffusion equation ...
    • Discrete Element Modelling Using a Parallelised Physics Engine 

      Longshaw, Stephen M.; Turner, Martin J.; Finch, Emma; Gawthorpe, Robert (The Eurographics Association, 2009)
      Discrete Element Modelling (DEM) is a technique used widely throughout science and engineering. It offers a convenient method with which to numerically simulate a system prone to developing discontinuities within its ...
    • Distance Based Feature Detection on 3D Point Sets 

      Ramli, Ahmad; Ivrissimtzis, Ioannis (The Eurographics Association, 2009)
      We propose a distance based algorithm for implicit feature detection on 3D point sets. Instead of directly determining whether a point belongs to a feature of the 3D point set or not, we first compute the distance between ...
    • An Edge-based Approach to Adaptively Refining a Mesh for Cloth Deformation 

      Simnett, Timothy J. R.; Laycock, Stephen D.; Day, Andy M. (The Eurographics Association, 2009)
      Simulating cloth in real-time is a challenging endeavour due to the number of triangles necessary to depict the potentially frequent changes in curvature, in combination with the physics calculations which model the ...
