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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Touching The Invisible - Molecular Haptics
(The Eurographics Association, 2009)
Novel, simple, cost-effective applications combining haptics and computer graphics for the study of key chemical concepts such as reactivity and periodicity at AS/A-level and undergraduate level are described.
Uncertain Flow Visualization using LIC
(The Eurographics Association, 2009)
In this paper we look at the Line Integral Convolution method for flow visualization and ways in which this can be applied to the visualization of two dimensional, steady flow fields in the presence of uncertainty. To ...
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 ...
Coastal Shelf Visualization using VTK and OpenDX of Hydro-Informatic Numerical Models
(The Eurographics Association, 2009)
Scientific visualization has an important role in climate change analysis, especially by creating dynamic interactive environments. The earth sciences, such as oceanography, utilize many numerical models; experts wish to ...
