An Evaluation of the use of Clustering Coefficient as a Heuristic for the Visualisation of Small World Graphs
(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 ... -
A Thin-plate CAD Mesh Model Splitting Approach Based on Fitting Primitives
(The Eurographics Association, 2010)Extracting structural information from mesh models is crucial for Simulation Driven Design (SDD) in industrial applications. Focusing on thin-plate CAD mesh models (the most commonly used parts in electronic products such ... -
Computer Graphics Education and the understanding of pixel plotting algorithms using Growth Aggregation models
(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 ... -
Sketch-Based Posing of 3D Faces for Facial Animation
(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 ... -
Multiresolution Modeling Using Fractal Image Compression Techniques
(The Eurographics Association, 2010)This work presents a new approach to the multiresolution modeling of polygonal meshes. This approach is based on the theoretically well-established fractal image compression techniques. A polygonal mesh is represented as ... -
The Effect of Discretised and Fully Converged Spatialised Sound on Directional Attention and Distraction
(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 ... -
Anatomically Plausible Surface Alignment and Reconstruction
(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 ... -
Audio-Visual Animation of Urban Space
(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 ... -
Integrating Haptic Interaction Into An Existing Virtual Environment Toolkit
(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 ... -
Pattern Recognition in Cytopathology for Papanicolaou Screening
(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 ... -
Surfel Based Geometry Reconstruction
(The Eurographics Association, 2010)We propose a method for retrieving a piecewise smooth surface from noisy data. In data acquired by a scanning process sampled points are almost never on the discontinuities making reconstruction of surfaces with sharp ... -
Remote Scientific Visualization for Large Datasets
(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 ... -
Perception of Clones in Forest Rendering
(The Eurographics Association, 2010)The application of instanced clones represents a powerful technique for reducing the time and space requirements of the storage and visualization of large populations of similar objects. This paper presents the results of ... -
3D Modelling of Complex Biological Structures: The Oviduct
(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 ... -
Screen Space Re-Rendering for the Simulation of Concert Lighting
(The Eurographics Association, 2010)The visualisation of modern concert lighting requires complex illumination models to be calculated at interactive frame rates. Each light may have 20 or more parameters which are all changing in real time. Here we present ... -
Evaluation of A Viseme-Driven Talking Head
(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 ... -
Computer Modelling of Theatrical Sets
(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 ... -
Comparison of Different Types of Visemes using a Constraint-based Coarticulation Model
(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 ... -
Approximating Poisson Disk Distributions by Means of a Stochastic Dither Array
(The Eurographics Association, 2010)Achieving blue noise point set distributions has been a common goal of two largely separate research communities: computer graphics and digital halftoning. Computer graphics research has focused largely on geometric solutions ... -
Efficient Image Blur in Web-Based Applications
(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 ...
