    • Data Driven Graphical Applications: A Fluid Approach 

      Jones, A.; Mantle, C.; Cornford, D. (The Eurographics Association, 2007)
      The inclusion of high-level scripting functionality in state-of-the-art rendering APIs indicates a movement toward data-driven methodologies for structuring next generation rendering pipelines. A similar theme can be seen ...

    • Delivering Effective and Usable Interactive 3D Visualization on Lightweight Mobile Devices 

      Holmes, I. R.; Kalawsky, R. S. (The Eurographics Association, 2007)
      3D visualization has significantly enhanced scientists ability to discover important new insights into their data. In this paper we focus specifically on associated HCI and human factors of remote 3D visualization. We ...

    • A Distance Hierarchy to Detect Collisions Between Deformable Objects 

      Madera, Francisco A.; Day, Andy M.; Laycock, Stephen D. (The Eurographics Association, 2007)
      To detect collisions between deformable objects we introduce an algorithm that computes the closest distances between certain feature points defined in their meshes. The strategy is to divide the objects into regions and ...

    • The Dynamic Animation of Ambulatory Arthropods 

      Cenydd, Llyr ap; Teahan, William (The Eurographics Association, 2007)
      Whilst advances in real-time computer graphics continue to permit the development of increasingly vivid virtual worlds, the degree of interaction between the environment and the animated characters within remains relatively ...

    • A Flexible Approach to High Performance Visualization Enabled Augmented Reality 

      Hughes, Chris J.; John, Nigel W. (The Eurographics Association, 2007)
      Commonly registration and tracking within Augmented Reality (AR) applications have been built around computer vision techniques that use limited bold markers, which allow for their orientation to be estimated in real-time. ...

    • GPU-Based Wind Animation of Trees 

      Skjermo, Jo (The Eurographics Association, 2007)
