SVG Linearization and Accessibility
(Blackwell Publishers, Inc and the Eurographics Association, 2002)The usage of SVG (Scaleable Vector Graphics) creates new possibilities as well as new challenges for theaccessibility of Web sites. This paper presents a metadata vocabulary to describe the information content ofan SVG ... -
Towards Interactive Real-Time Crowd Behavior Simulation
(Blackwell Publishers, Inc and the Eurographics Association, 2002)While virtual crowds are becoming common in non-real-time applications, the real-time domain is still relativelyunexplored. In this paper we discuss the challenges involved in creating such simulations, especially the ... -
Hierarchical Impostors for the Flocking Algorithm in 3D
(Blackwell Publishers, Inc and the Eurographics Association, 2002)The availability of powerful and affordable 3D PC graphics boards has made the rendering of rich immersiveenvironments possible at interactive speeds. The scene update rate and the appropriate behaviour of objects withinthe ... -

Visualizing Crowds in Real-Time
(Blackwell Publishers, Inc and the Eurographics Association, 2002)Real-time crowd visualization has recently attracted quite an interest from the graphics community and, asinteractive applications become even more complex, there is a natural demand for new and unexplored applicationscenarios. ... -
A Spoken Dialogue System for Navigation in Non-Immersive Virtual Environments
(Blackwell Publishers, Inc and the Eurographics Association, 2002)Navigation is the process by which people control their movement in virtual environments and is a corefunctional requirement for all virtual environment (VE) applications. Users require the ability to move, controllingorientation, ... -
Synthetic Vision and Memory for Autonomous Virtual Humans
(Blackwell Publishers, Inc and the Eurographics Association, 2002)A memory model based on 'stage theory', an influential concept of memory from the field of cognitive psychology,is presented for application to autonomous virtual humans. The virtual human senses external stimuli througha ... -
A Skeleton-based Approach for Detection of Perceptually Salient Features on Polygonal Surfaces
(Blackwell Publishers, Inc and the Eurographics Association, 2002)The paper presents a skeleton-based approach for robust detection of perceptually salient shape features. Given ashape approximated by a polygonal surface, its skeleton is extracted using a three-dimensional Voronoi ... -
Vortex Tracking and Visualisation in a Flow Past a Tapered Cylinder
(Blackwell Publishers, Inc and the Eurographics Association, 2002)In this paper we explore a novel combined application of two of our existing visualisation techniques to thetracking of 3D vortex tubes in an unsteady flow. The applied techniques are the winding-angle vortex extractiontechnique ... -
