      This paper presents an alternative to existing methods for remotely accessing Virtual Reality (VR) systems. Common solutions are based on specialised software and/or hardware capable of rendering 3D content, which not only ...
    • skML a Markup Language for Distributed Collaborative Visualization 

      Duce, D. A.; Sagar, M. (The Eurographics Association, 2005)
      This paper describes a reference model and a markup language for representing processing and dataflow in distributed collaborative visualization applications. The language, skML, enables processing to be represented at ...
    • Towards Realism in Facial Image Prototyping: Results of a Wavelet MRF Method 

      Tiddeman, Bernard; Stirrat, Michael; Perrett, David (The Eurographics Association, 2005)
      The ability to combine multiple images to produce a composite that is representative of the set has applications in psychology research, medical imaging and entertainment. Current techniques using a combination of image ...
    • Simulation and Visualization of a large scale Real Time Multi-Robot system 

      Al-Hudhud, G.; Ayesh, A.; Istance, H. (The Eurographics Association, 2005)
      This paper describes the software implementation and the visualization aspects of an interaction-communication protocol within a large scalable multi-robot system. It investigates the current communication protocols within ...
    • Visualization of Smoothed Particle Hydrodynamics for Astrophysics 

      Walker, Rick; Kenny, Peter; Miao, Jingqi (The Eurographics Association, 2005)
      Scientific visualization still presents a number of challenges. Effective visualization straddles several problem domains - the data structures needed to support visualization of large data sets, rendering techniques for ...
    • Freehand 3D Curve Recognition and Oversketching 

      Han, Li; Amicis, Raffaele De; Conti, Giuseppe (The Eurographics Association, 2005)
      In the CAD/CAS field, the increasing domination of spline-based graphic objects has driven a great attention to methods focusing on the management of free-form curves. Based on the quick brainstorm illustration and stepwise ...
    • Integrating Abstract and Physical Molecular Model Interaction 

      Thorne, Dave; Pettifer, Steve; Attwood, Terri (The Eurographics Association, 2005)
      Historically, bioinformaticians have carried out protein analysis in one of two ways: by concentrating on either the physical structural representation of the subject data or a more abstract sequential representation. This ...
    • Click and Brush: A Novel Way of Finding Correlations and Relationships in Visualizations 

      Wright, Michael A. E.; Roberts, Jonathan C. (The Eurographics Association, 2005)
      Brushing is a commonly used interaction technique that allows users to select items or an area of the visualization as the user moves the mouse. Brushing is often used with multiple views, where any co-related information ...
    • Arachnid Simulation: Scaling Arbitrary Surfaces 

      Cenydd, L. ap; Teahan, W. (The Eurographics Association, 2005)
      There has been little research done into the realistic simulation of creatures with the ability to crawl across arbitrary surfaces, clamber up walls and walk across ceilings. Realistic simulation of such feats would be of ...
