      This work-in-progress paper describes some of the issues, and lists proposed use-case scenarios, for the development of a real-time multi-participant 3D enhanced videoconferencing system. We are interested in creating a ...
    • Advantages of allowing Hexagonal Pixels to be used as a Boundary Description Format 

      Turner, Martin J. (The Eurographics Association, 2007)
      This paper considers some algorithmic extensions and some specific advantages when using a hexagonal pixel array as compared with the usual practice of using a rectangular or square pixel raster array. Discussed are some ...
    • Aesthetic-Interaction: Exploring the Importance of the Visual Aesthetic in the Creation of Engaging Photorealistic VR Environments 

      Carroll, Fiona (The Eurographics Association, 2009)
      Nearly forty years since its conception, the medium of VR is still an enigma. In many ways, it is a medium that still lacks its own uniform language. VR, and particularly photorealistic VR, is a medium that is so occupied ...
    • Agent-based Large Scale Simulation of Pedestrians With Adaptive Realistic Navigation Vector Fields
