    • 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 ...
    • 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 ...
    • 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 ...
    • Space-free Shader Programming: Automatic Space Inference and Optimization for Real-time Shaders 

      Lejdfors, Calle; Ohlsson, Lennart (The Eurographics Association, 2008)
      The graphics processing units (GPUs) used in todays personal computers can be programmed to compute the visual appearance of three-dimensional objects in real time. Such programs are called shaders and are written in ...
    • Time Handling in Inverse Daylighting for CAAD 

      Tourre, Vincent; Martin, Jean-Yves; Hégron, Gérard (The Eurographics Association, 2008)
      This paper presents an integration of time dimension in an inverse natural lighting model. This model allows to aid the design of building openings starting from the designed volume and lighting intentions. As natural ...
    • Time-varying Image Data Visualization Framework for Application in Cardiac Catheterization Procedures 

      Ma, Ying Liang; Rhode, Kawal S.; King, Andy P.; Gao, Gang; Chinchapatnam, Phani; Schaeffter, Tobias; Razavi, Reza; Saetzler, Kurt (The Eurographics Association, 2008)
      Visualization plays an important role in image guided surgery. This paper presents a real-time 3D motion visualization method where pre-computed meshes of the beating heart are synchronized with and overlaid onto live X-ray ...
    • Towards Image Rendering using models of Image Manifolds 

      Woodland, A.; Labrosse, F. (The Eurographics Association, 2008)
      Building computer representations of real objects, which could be archaeological artifacts or planned buildings, is a very active research area. Typically objects are represented in computer memory as a collection of ...
