    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
