    • Comparison of Different Types of Visemes using a Constraint-based Coarticulation Model 

      Lazalde, Oscar M. Martinez; Maddock, Steve (The Eurographics Association, 2010)
      A common approach to producing visual speech is to interpolate the parameters describing a sequence of mouth shapes, known as visemes, where visemes are the visual counterpart of phonemes. A single viseme typically represents ...
    • Computer Graphics Education and the understanding of pixel plotting algorithms using Growth Aggregation models 

      Roberts, Jonathan (The Eurographics Association, 2010)
      It is sometimes difficult to teach fundamental aspects of computer graphics, especially pixel plotting techniques, as some students fail to engage with the material. In this paper we describe a constructionist approach to ...
    • Computer Modelling of Theatrical Sets 

      Stephenson, Ian; Pride, Rebecca (The Eurographics Association, 2010)
      Here we discuss the design and implementation of a modelling tool specifically targeted for use by designers of theatrical sets. By applying domain specific knowledge and contraints to the design of the software, we ...
    • Craniofacial Reconstruction Based on Skull-face Models Extracted from MRI Datasets 

      Salas, Miguel; Maddock, Steve (The Eurographics Association, 2010)
      We present a method for extracting skull and face models from MRI datasets and show how the resulting dataset is used in a craniofacial reconstruction (CFR) system. Datasets for 60 individuals are used to produce a database ...
    • The Effect of Discretised and Fully Converged Spatialised Sound on Directional Attention and Distraction 

      Harvey, Carlo; Walker, Steve; Bashford-Rogers, Thomas; Debattista, Kurt; Chalmers, Alan (The Eurographics Association, 2010)
      A major challenge in Virtual Reality (VR) is to be able to provide interactive rates of realism. However this is very computationally demanding and only recently has high-fidelity rendering become close to interactive rates ...
    • Efficient Image Blur in Web-Based Applications 

      Kraus, Martin (The Eurographics Association, 2010)
      Scripting languages require the use of high-level library functions to implement efficient image processing; thus, real-time image blur in web-based applications is a challenging task unless specific library functions are ...
    • Evaluation of A Viseme-Driven Talking Head 

      Dey, Priya; Maddock, Steve; Nicolson, Rod (The Eurographics Association, 2010)
      This paper introduces a three-dimensional virtual head for use in speech tutoring applications. The system achieves audiovisual speech synthesis using viseme-driven animation and a coarticulation model, to automatically ...
    • An Evaluation of the use of Clustering Coefficient as a Heuristic for the Visualisation of Small World Graphs 

      McGee, Fintan; Dingliana, John (The Eurographics Association, 2010)
      Many graphs modelling real-world systems are characterised by a high edge density and the small world properties of a low diameter and a high clustering coefficient. In the "small world" class of graphs, the connectivity ...
    • From Tabular Data to Metaphoric Landscape Visualisation - A Template-based Approach 

      Mohamed, Farhan; Chen, Min; Grant, Phil W. (The Eurographics Association, 2010)
      This paper presents a template-based approach to the generation of metaphoric visualisation from tabular data. This technique allows a coherent transformation between a relatively abstract visual representation (e.g., a ...
    • ID-Based Rendering of Silhouettes on GPU 

      Diktas, Engin Deniz; Sahiner, Ali Vahit (The Eurographics Association, 2010)
      When rendering object-silhouettes preprocessing is generally done primarily on the CPU. To this end primitive normals must be made consistent and the silhouette-edges need to be extracted every time the view-point is ...
    • Implicit Surface Reconstruction and Feature Detection with a Learning Algorithm 

      Kaye, David; Ivrissimtzis, Ionnis (The Eurographics Association, 2010)
      We propose a new algorithm for implicit surface reconstruction and feature detection. The algorithm is based on a self organising map with the connectivity of a regular 3D grid that can be trained into an implicit ...
    • An Improved Discrete Level of Detail Model Through an Incremental Representation 

      Ribelles, Jose; López, Angeles; Belmonte, Oscar (The Eurographics Association, 2010)
      Real-time applications such as computer and video games, virtual reality and scientific simulation require rendering of complex models for realism. Graphics rendering engines include multiresolution modelling techniques ...
    • Integrating Haptic Interaction Into An Existing Virtual Environment Toolkit 

      Scopes, Peter; Smith, Shamus P. (The Eurographics Association, 2010)
      There is increasing demand for haptic, or touch-based, interaction in virtual environments. Although many haptic devices come with APIs to enable the development of haptic-based applications, many do not provide the same ...
    • Interval Based Data Structure Optimization 

      Duffy, Brian; Carr, Hamish (The Eurographics Association, 2010)
      Isosurface extraction is a widely exploited visualization technique for volumetric data on all manner of grid representation. The basic technique is often used to explore and measure many properties of data sets of ever ...
    • A Multi-Windows Approach for Sketch-Based Conceptual Design System 

      Gharib, Islam; Qin, Shengfeng (The Eurographics Association, 2010)
      Sketching plays a very important role in conceptual design. In this early stage of the design process, designers have developed some ways to help them to explore designs. Sketching is one of these methods. In this paper, ...
