This paper describes a technique to allow the real-time simulation of snowfall accumulation in a dynamic 3D environment. The implementation maps surface-bound accumulation buffers to each object in the scene, forming height-maps of accumulated snow cover. The environment is rendered from above similar to the way shadow mapping is typically ...

As scanning technologies improve new approaches to digitizing cultural heritage artefacts emerge. The use of micro--computed tomography (micro-CT) presents an interesting approach as it is capable of high-resolution scans of not just the surface of the artifact but also the intricate internal structures and volumes leading to more complete digitization ...

Haptic assistance is an emerging field of research that is designed to improve human-computer interaction (HCI) by reducing error rates and targeting times through the use of force feedback. Haptic feedback has previously been investigated to assist motion-impaired computer users, however, limitations such as target distracters have hampered its integration ...

Laser scanning has been widely adopted for the digital preservation and study of cultural heritage artifacts. However, surface scans alone are not sufficient for a variety of intricate objects such as the Cantonese chess pieces that were delicately carved from ivory throughout the 19th Century. These pieces incorporate a puzzle ...

To create traffic simulations of high visual-fidelity, each component part needs to be designed and modelled in great detail. Roads can be created manually, but this can become a time-consuming and laborious process when modelling large-scale networks. Therefore, automated techniques for generating road networks efficiently and effectively, is highly desirable ...

In recent years, typical desktop computer screen sizes and resolutions have increased significantly. The result of this is that a pointing device has to travel a much greater distance to navigate the whole of a computer screen. For motion-impaired operators that suffer from fatigue or have a limited range of ...

Haptic assistance is the process of using force feedback to aid the operator in human-computer interaction (HCI). This may take the form of guiding the operator toward a target or assisting them in its selection. Haptic feedback has previously been investigated to assist motion-impaired computer users; however, limitations of previous ...

To create traffic simulations of high visual-fidelity, each road needs to be designed and modelled in great detail to conform with the governing rules and regulations of highway design. Roads could be created manually, but this can become a time-consuming and laborious process when modelling large-scale networks. Therefore, automated techniques ...

Archive cartography and archaeologist's sketches are invaluable resources when analysing a historic town or city. A virtual reconstruction of a city provides the user with the ability to navigate and explore an environment which no longer exists to obtain better insight into its design and purpose. However, the process of ...

A haptic feedback device enables a user to manipulate three dimensional structures and feel forces contained within complex data-sets such as those resulting from computational biology. However, as the data-set grows in size it becomes difficult to ensure that the user can easily interact with every part of it. One ...

A discrete collision detection algorithm to detect self-collisions between deformable objects is presented, this is built up using a Bounding Volume Hierarchy (BVH) and a Feature-based method. The deformations are represented by the features of the mesh, which are withinthe bounding volumes and consequently the updating time for the BVH ...

Reconstructions of large cultural heritage sites, at multiple time periods, facilitate public awareness, enable the visualisation of regeneration proposals, and assist archaeologists in establishing the validity of a particular hypothesis within context. This paper focuses on the reconstruction of sites that no longer exist, where archived cartography and archaeologist's sketches ...

An algorithm to detect collisions between both rigid and deformable objects is presented. The approach exploits benefits of a Bounding Volume Hierarchy (BVH) and a Feature-based method. The BVH decomposes the three dimensional polygonal objects into a hierarchy of spheres. The lowest level of the hierarchy is formed utilising spheres ...

Haptic rendering is the process of calculating and displaying physical forces to a user. Used concomitantly with a virtual environment it can further enhance a user's immersive experience whilst they interact with computer graphics. Haptic Feedback has been applied to the study of molecular systems for several years, however, computation ...

Visualising in real-time high quality virtual environments, which are suitable for cultural heritage and virtual tourism, is often a challenging endeavour. This is primarily, due to the cost of rendering complex architectural structures. Incorporating the sense of touch into real time environments enhances a user's experience, leading towards a higher ...
