Visual Saliency for Smell Impulses and Application to Selective Rendering
(The Eurographics Association, 2011)A major challenge in generating high-fidelity virtual environments is to be able to provide interactive rates of realism. However this is very computationally demanding and only recently visual perception has been used in ... -
Dynamic Video Face Transformation Using Multilinear and Autoregressive Models
(The Eurographics Association, 2011)In this paper we present a prototype system for altering perceived attributes of faces in video sequences, such as the apparent age, sex or emotional state. The system uses multilinear models to decompose the parameters ... -
Evaluation of a Reconfigurable Tangible Device for Collaborative Manipulation of Objects in Virtual Reality
(The Eurographics Association, 2011)In this paper we introduce an evaluation of a Reconfigurable Tangible Device (RTD) for collaborative manipulation of objects in virtual environments. The considered RTD, called RTD-3, has a triangular shape that naturally ... -
A Low-Cost Single-Pixel Thermographic Camera
(The Eurographics Association, 2011)A working prototype of single-pixel thermographic camera which can be built for 100 Euros is presented. It is based on a pyrometer's sensor (thermopile with optics) and two mirrors mounted on servos to scan horizontally ... -
Airborne Ultrasound Pulse Force Device for Palpation Simulation
(The Eurographics Association, 2011)This research is investigating the use of acoustic radiation pressure from ultrasound emitters to produce tactile feedback in medical simulators. An initial application would be to simulate a pulse palpation where the ... -
Morphological Analysis from Images of Hyphal Growth using a Fractional Dynamic Model
(The Eurographics Association, 2011)The development of methods capable of accurately characterising the morphology of filamentous microbes represents a significant challenge to biotechnologists. This is because the productivity of many industrial fermentation ... -
A Desktop Multi-Touch Interface for Posing Characters
(The Eurographics Association, 2011)Multi-touch, direct manipulation interfaces have become common in mobile media applications, but their use on the desktop is limited. In this paper we propose that multi touch direct manipulation is well suited to the ... -
Simple and Efficient Normal Encoding with Error Bounds
(The Eurographics Association, 2011)Normal maps and bump maps are commonly used techniques to make 3D scenes more realistic. Consequently, the efficient storage of normal vectors is an important task in computer graphics. This work presents a fast, lossy ... -
Visualisation of Blockplay in Early Childhood
(The Eurographics Association, 2011)Observation of young children is common in educational settings. For trainee practitioners however, access to children is infrequent, and even then, only small amounts of observable activity can be captured. We have developed ... -
Model and Visualise the Relationship between Energy Consumption and Temperature Distribution in Cold Rooms
(The Eurographics Association, 2011)In the area of food and pharmacy cold storage, temperature distribution is considered as a key factor. Inappropriate distribution of temperature during the cooling process in cold rooms will cause the deterioration of the ... -
Remodelling of Botanical Trees for Real-Time Simulation
(The Eurographics Association, 2011)This paper proposes a technique to use virtual trees created with an industry recognised modelling tool. Initially the skeletal structure is extracted and processed to generate a continuous mesh suitable for high quality, ... -
Terrain Models for Mass Movement Erosion
(The Eurographics Association, 2011)In this paper we present a particle-based method for large scale long time progressive simulation of terrain erosion containing wet granular particles. The wetting process and the propagation through granular material is ... -
Advantages of 3D Extraction and Spatial Awareness within a Videoconferencing Environment
(The Eurographics Association, 2011)This work-in-progress paper describes some of the issues, and lists proposed use-case scenarios, for the development of a real-time multi-participant 3D enhanced videoconferencing system. We are interested in creating a ... -
Memory Efficient Surface Reconstruction Based on Self Organising Maps
(The Eurographics Association, 2011)We propose a memory efficient, scalable surface reconstruction algorithm based on self organising maps (SOMs). Following previous approaches to SOM based implicit surface reconstruction, the proposed SOM has the geometry ... -
Interactive Computer Visualisations of Time and Place
(The Eurographics Association, 2011)This paper describes research into the development of a composition portfolio themed on interactive computer-based visualisations of time and place. The application of various computer graphics techniques are discussed ... -
Pixel-Level Algorithms for Drawing Curves
(The Eurographics Association, 2011)This paper introduces new pixel level algorithms for parametric curves. The optimal value of the steps is first derived when rastrerizing parametric curves. A double-step algorithm using only integer arithmetic is presented ... -
Enabling Visualization of Massive Datasets Through MPP Database Architecture
(The Eurographics Association, 2011)We are developing a novel visualization architecture which is specifically designed to render very large (terabyte scale) datasets. Our method differs from the classic visualization pipeline of Harber and McNabb. In ... -
Building a Video Wall for Earth Observation Data
(The Eurographics Association, 2011)Earth observation satellites are generating large amounts of data as they monitor the earth' environment. Large scale visualisation represents a powerful mechanism to explore and communicate this data; however, conventional ... -
Compositing Shaders in X3D
(The Eurographics Association, 2011)We present a new approach for implementing effects using the GPU shading languages. Our effects seamlessly cooperate with each other and with the shaders used internally by the 3D application. Thus the effects are reusable, ...
