    • Efficient Path Matching Motion Generation Algorithm for Multi Agent Environment 

      Lau, Newman; Chow, Chapmann; Lee, Pouro; Iu, Bartholomew (The Eurographics Association, 2008)
      This paper presents an efficient method to generate a large amount of continuous motion data from motion captured data. Given user defined way point lists for each agent, the algorithm can automatically generate collision ...

    • A New Method for Interacting with Multi-Window Applications on Large, High Resolution Displays 

      Rooney, Chris; Ruddle, Roy A. (The Eurographics Association, 2008)
      Physically large display walls can now be constructed using off-the-shelf computer hardware. The high resolution of these displays (e.g., 50 million pixels) means that a large quantity of data can be presented to users, ...

    • A Lemon is not a Monstar: Visualization of Singularities of Symmetric Second Rank Tensor Fields in the Plane 

      Liu, J.; Hewitt, W. T.; Lionheart, W. R. B.; Montaldi, J.; Turner, M. (The Eurographics Association, 2008)
      In the visualization of the topology of second rank symmetric tensor fields in the plane one can extract some key points (degenerate points), and curves (separatrices) that characterize the qualitative behaviour of the ...

    • 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 ...

    • 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

    • Modes of Virtual Environments Integrated within Collaborative Environments 

      McDerby, M. J.; Turner, M. J.; Leaver, G. W. (The Eurographics Association, 2008)
      This paper describes the timeline of large display virtual environments used by Manchester Visualization Centre and a few of the main applications of such systems. Moreover, it describes a few simple common modes of use ...

    • 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 Benchmarking Framework for Static Collision Detection 

      Diktas, Engin Deniz; Sahiner, Ali Vahit (The Eurographics Association, 2008)
      Performanceof static collision detection queries depends on the type of the hierarchy chosen as well as the relative positioning of the colliding objects. In order to evaluate the performance of bounding volume hierarchies, ...
