  • 3D Modelling of Complex Biological Structures: The Oviduct 

    Burkitt, Mark; Romano, Daniela M.; Walker, Dawn C.; Fazeli, Alireza (The Eurographics Association, 2010)
    A novel technique using a particle system constrained by Newtonian forces is presented for the algorithmic construction of small scale, complex 3D biological structures based on real world biological data. This allows ...
  • Anatomically Plausible Surface Alignment and Reconstruction 

    Paulsen, Rasmus R.; Larsen, Rasmus (The Eurographics Association, 2010)
    With the increasing clinical use of 3D surface scanners, there is a need for accurate and reliable algorithms that can produce anatomically plausible surfaces. In this paper, a combined method for surface alignment and ...
  • 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 ...
  • Using the Discrete Fourier Transform for Character Motion Blending and Manipulation - a Streamlined Approach 

    Molnos, Michael R. L.; Laycock, Stephen D.; Day, Andy M. (The Eurographics Association, 2010)
    Motion capture data allows natural-looking motion to be bestowed upon simulated characters. Research has sought ways of extending the range of motions it can reproduce. One such method involves blending between captured ...
  • Animating Horse Gaits and Transitions 

    Murphy, James E.; Carr, Hamish; O'Neill, Michael (The Eurographics Association, 2010)
    Animations of horses are commonly used for entertainment purposes. A realistic animated model must move with a gait appropriate to its velocity. We present a kinematic animation system in which a horse model moves using ...
  • Sketch-Based Posing of 3D Faces for Facial Animation 

    Gunnarsson, Orn; Maddock, Steve (The Eurographics Association, 2010)
    This paper presents a novel approach to creating 3D facial animation using a sketch-based interface where the animation is generated by interpolating a sequence of sketched key poses. The user does not need any knowledge ...
  • 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 ...
  • 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 ...
  • 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, ...
  • 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 ...
  • Audio-Visual Animation of Urban Space 

    Richmond, Paul; Smyrnova, Yuliya; Maddock, Steve; Kang, Jian (The Eurographics Association, 2010)
    We present a technique for simulating accurate physically modelled acoustics within an outdoor urban environment and a tool that presents the acoustics alongside a visually rendered counterpart. Acoustic modelling is ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Remote Scientific Visualization for Large Datasets 

    Turner, Martin; Leaver, George; Perrin, James (The Eurographics Association, 2010)
    Remote scientific visualization, where rendering services are provided by larger scale systems than are available on the desktop, are becoming increasingly important as dataset sizes increase beyond the capabilities of ...
  • 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 ...
  • Pattern Recognition in Cytopathology for Papanicolaou Screening 

    Blackledge, Jonathan; Dubovitskiy, D. A. (The Eurographics Association, 2010)
    A unique space oriented filer is presented in order to detect and isolate the cell of a nucleus for applications in cytopathology. A classification method for nuclei is then considered based on the application of a set of ...
  • 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 ...
  • 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 ...
