Design and Evaluation of a Hardware Accelerated Ray Tracing Data Structure
(The Eurographics Association, 2009)The increase in graphics card performance and processor core count has allowed significant performance accel- eration for ray tracing applications. Future graphics architectures are expected to continue increasing the ... -
Developing an Application to Provide Interactive Threedimensional Visualisation of Bone Fractures
(The Eurographics Association, 2009)The main research question for this work is: What are the factors involved in developing a three-dimensional (3D) interactive model of a bone fracture and how best may these be addressed? This paper presents work in progress ... -
Diffusion and Fractional Diffusion Based Image Processing
(The Eurographics Association, 2009)We consider the background to describing strong scattering in terms of diffusive processes based on the diffusion equation. Intermediate strength scattering is then considered in terms of a fractional diffusion equation ... -
Discrete Element Modelling Using a Parallelised Physics Engine
(The Eurographics Association, 2009)Discrete Element Modelling (DEM) is a technique used widely throughout science and engineering. It offers a convenient method with which to numerically simulate a system prone to developing discontinuities within its ... -
Distance Based Feature Detection on 3D Point Sets
(The Eurographics Association, 2009)We propose a distance based algorithm for implicit feature detection on 3D point sets. Instead of directly determining whether a point belongs to a feature of the 3D point set or not, we first compute the distance between ... -
An Edge-based Approach to Adaptively Refining a Mesh for Cloth Deformation
(The Eurographics Association, 2009)Simulating cloth in real-time is a challenging endeavour due to the number of triangles necessary to depict the potentially frequent changes in curvature, in combination with the physics calculations which model the ... -
Facial Expression Transferring with a Deformable Model
(The Eurographics Association, 2009)This paper presents an automated approach to transferring facial expressions from a generic facial model onto various individual facial models without requiring any prior correspondences and manual interventions during the ... -
Fast and Accurate Finite Element Method for Deformation Animations
(The Eurographics Association, 2009)We present a matrix clustering method for speeding up finite element computations for non-rigid object animation. The method increases the efficiency of computing deformation dynamics through a compression scheme that ... -
A Framework for Physically Based Forest Fire Animation
(The Eurographics Association, 2009)Abstract In this paper, we propose a conceptual framework for animating physically based forest fires. Animating forest fire is a computationally demanding task as trees are intricate structures and fire is a highly complex ... -
A Haptic System for Drilling into Volume Data with Polygonal Tools
(The Eurographics Association, 2009)With the developments of volume visualization technology for complex data sets comes new challenges in terms of user interaction and information extraction. Volume haptics has proven itself to be an effective way of ... -
Hardware Accelerated Shaders Using FPGAs
(The Eurographics Association, 2009)We demonstrate that Field Programable Gate Arrays (FPGAs) can be used to accelerate shading of surfaces for production quality rendering (a task standard interactive graphics hardware is generally ill-suited to) by allowing ... -
Higher Dimensional Vector Field Visualization: A Survey
(The Eurographics Association, 2009)Vector field visualization research has evolved very rapidly over the last two decades. There is growing consensus amongst the research community that the challenge of two-dimensional vector field visualization is virtually ... -
An Improved Precise Multi-contact Haptic Visualization
(The Eurographics Association, 2009)We present an improved multi-contact haptic visualization method based on the Spatialized Normal Cone Hier- archies (SNCH). Though this approach is not entirely new, we have implemented several improvements in order to ... -
Influencing User Attention Using Real-Time Stylised Rendering
(The Eurographics Association, 2009)In this paper, we present a series of experiments that were conducted to further understand how using adaptive levels of artistic abstraction within an interactive 3D scene can influence user gaze behaviour. We found that ... -
Interactive Relighting for Stage Use
(The Eurographics Association, 2009)Re-lighting by combining images taken under known lighting conditions to synthesise new lighting configurations is a simple, but powerful technique capable of producing impressive results. However it has found little ... -
Markerless Visual Human Movement Tracking for HCI: What Frequency?
(The Eurographics Association, 2009)This paper tries to establish a minimal tracking frequency limit for visual human movement tracking algorithms that intend to be useful for the realization of some kind Human-Computer-Interaction (HCI) metaphor. More ... -
Multimodal Visualization with Interactive Closeups
(The Eurographics Association, 2009)Abstract Closeups are used in illustrations to provide detailed views on regions of interest. They are integrated into the rendering of the whole structure in order to reveal their spatial context. In this paper we present ... -
Near-correct Ocular Accommodation Responses to a 3d Display, Using Multiple Image Planes and Depth Filtering
(The Eurographics Association, 2009)Conventional stereo displays provide incorrect focus cues because the image is presented on a single surface. This is known to cause a number of aversive symptoms in users, including fatigue and discomfort. Multiple-focal-plane ... -
Object Interaction Using Tabulated Spheres Subsets
(The Eurographics Association, 2009)Tabulated Sphere Subsets (TSSs) provide a fast way to approximate collision tests between objects whose motion is constrained. A TSS is a subset of a set of spheres that approximate the shape of two objects that might ... -
Real-time Rendering of Deformable Translucent Objects
(The Eurographics Association, 2009)This paper introduces an efficient real-time shading model to simulate light transport in translucent materials. In this work no pre-processing step is needed, allowing us to deform translucent objects at interactive rates. ...
