    • Localised Topology Correction for Hypertextured Terrains 

      Gamito, Manuel N.; Maddock, Steve C. (The Eurographics Association, 2008)
      Terrains for computer graphics have traditionally been modelled with height fields. In the case of procedurally defined terrains, the height field is generated by a displacement map z

    • Contouring with Uncertainty 

      Osorio, R. S. Allendes; Brodlie, K. W. (The Eurographics Association, 2008)
      The visualization of uncertainty remains one of the major challenges for the visualization community. To achieve this, we need to understand and develop methods that allow us not only to consider uncertainty as an extra ...

    • Self-Organising Maps for Implicit Surface Reconstruction 

      Yoon, Mincheol; Ivrissimtzis, Ioannis; Lee, Seungyong (The Eurographics Association, 2008)
      This paper proposes an implicit surface reconstruction algorithm based on Self-Organising Maps (SOMs). The SOM has the connectivity of a regular 3D grid, each node storing its signed distance from the surface. At each ...

    • 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 ...

    • Segmenting the External Surface of a Human Skull in MR Data 

      Salas, M.; Maddock, S. (The Eurographics Association, 2008)
      A method is presented to extract the outline of the skull region in coronal Magnetic Resonance (MR) images from the Visible Human Project. The starting point is the formulation of a Gradient Vector Flow (GVF) snake extended ...

    • Light Field Rendering for Games 

      Todt, S.; Rezk-Salama, C.; Kolb, A. (The Eurographics Association, 2008)
      This paper studies the problem of integrating high-quality light field rendering into state-of-the-art real-time computer games. We present a complete production pipeline for generation of light fields from arbitrary complex ...

    • Efficient Representation of Layered Depth Images for Real-time Volumetric Tests 

      Trapp, Matthias; Döllner, Jürgen (The Eurographics Association, 2008)
      Representing Layered Depth Images (LDI) as 3D texture can be used to approximate complex, arbitrarily shaped volumes on graphics hardware. Based on this concept, a number of real-time applications such as collision detection ...

    • A Physical Model for the Polarized Scattering of Light 

      Brayford, David; Turner, Martin; Hewitt, W. T. (The Eurographics Association, 2008)
      The change in polarization state due to the interaction of light with the surface and beneath the surface of an object has become increasingly important in realistic image synthesis of materials such as metallic, iridescent ...

    • Interactive Out-of-Core Exploration of Large Volume Datasets in VTK-Based Visualisation Systems 

      Agrawal, A.; Kohout, J.; Clapworthy, G. J.; McFarlane, N. J. B.; Dong, F.; Viceconti, M.; Taddei, F.; Testi, D. (The Eurographics Association, 2008)
      The Visualisation ToolKit (VTK) has become a very popular tool for scientific data visualisation and it is used as a base in many existing visualisation systems. Scientific datasets produced nowadays by complex scientific ...

    • Steering Chemistry in the Right Direction! 

      Davies, R. A. (The Eurographics Association, 2007)
      The development of novel molecular visualization and computational steering applications is described in this paper. Improvements to the Molecular Visualizer application, jointly developed between the schools of Chemistry ...

    • Anatomy Education using Rapid Prototyping 

      Thomas, Rhys G.; John, Nigel W.; Lim, Ik Soo (The Eurographics Association, 2007)
      Rapid Prototyping is a technique which is rapidly gaining interest amongst the medical community for many different purposes. In this paper we present a novel tool that uses rapidly prototyped models to serve as an interaction ...

    • A 3D Visualisation Environment Modelling the Evolution of North-West Europe since the Last Glacial Maximum 

      Wainwright, Adam; Varsamidis, Thomas; Scourse, James (The Eurographics Association, 2007)
      This work in progress aims to provide an interactive 3D visualisation allowing real time manipulation of glacial isostatic adjustment (GIA) model output data which reconstructs the ice distribution and coastline position ...

    • Streaming and Data Enrichment 

      McDerby, Mary J.; Hewitt, William T.; Turner, Martin J. (The Eurographics Association, 2007)
      Data is being created at a continuously increasing rate. Scientists are drowning in their data . So much so they cannot visualize the data to see the big picture. This work-in-progress paper describes a data capture and ...

    • Using 3D Visualisation in the Repair of Intra-articular Fractures 

      Wilson, A. F.; Musgrove, P. B.; Buckley, K. A.; Pearce, G.; Geoghegan, J. (The Eurographics Association, 2007)
      The overall aim of this work in progress is to use visualisation to provide a tool for pre-operative planning of surgery on complex fractures, in particular for intra-articular fractures. Currently, a patient suffering ...

    • Level of Detail for Physically Based Fire 

      Gundersen, Odd Erik; Tangvald, Lars (The Eurographics Association, 2007)
