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 ... -
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 ... -
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 ... -
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 ... -
From Tabular Data to Metaphoric Landscape Visualisation - A Template-based Approach
(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
(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
(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
(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
(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
(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
(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, ... -
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 ... -
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 ... -
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 ... -
Real-Time Traffic Simulation Using Cellular Automata
(The Eurographics Association, 2010)In this paper, we present a method to simulate large-scale traffic networks, at real-time frame-rates. Our novel contributions include a method to automatically generate a road graph from real-life data, and our extension ... -
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 ... -
Rendering Large Point Datasets with GPU Shaders
(The Eurographics Association, 2010)This paper demonstrates how programmable GPUs are a powerful tool to display large point datasets at an interactive frame rate. Point datasets are commonly used to analyse and solve complex problems, but rendering them is ... -
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 ... -
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 ... -
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 ...
