Accurate Simplification of Multi-Chart Textured Models
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Scanning and acquisition methods produce highly detailed surface meshes that need multi-chart parameterizations to reduce stretching and distortion. From these complex shape surfaces, high-quality approximations are ... -
Application of Visual Analytics for Thermal State Management in Large Data Centres
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Today s large data centres are the computational hubs of the next generation of IT services. With the advent of dynamic smart cooling and rack level sensing, the need for visual data exploration is growing. If administrators ... -
Arbitrary Importance Functions for Metropolis Light Transport
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present a generalization of the scalar importance function employed by Metropolis Light Transport (MLT) and related Markov chain rendering algorithms. Although MLT is known for its user-designable mutation rules, we ... -
Binary Shading Using Appearance and Geometry
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In the style of binary shading, shape and illumination are depicted using two colours, typically black and white, which form coherent lines and regions in the image. We formulate the problem of assigning colours in the ... -
BqR-Tree: A Data Structure for Flights and Walkthroughs in Urban Scenes with Mobile Elements
(The Eurographics Association and Blackwell Publishing Ltd, 2010) -
Computational Aesthetics 2010 in London, England, June 14-15, 2010, sponsored by Eurographics, in collaboration with ACM SIGGRAPH
(The Eurographics Association and Blackwell Publishing Ltd, 2010) -
A Copula-Based BRDF Model
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In this paper, we introduce a novel approach for modeling surface reflection. We focus on using a family of probability distributions called Archimedean copulas as BRDF models. The Archimedean representation has an attractive ... -
Designing a Highly Immersive Interactive Environment: The Virtual Mine
(The Eurographics Association and Blackwell Publishing Ltd, 2010)To achieve a full-scale simulation of a pyrite mine, a highly immersive environment becomes necessary and this research has led to a complex system enabling users to walk through a virtual mine in real time, presenting all ... -
Elastic Tubes: Modeling Elastic Deformation of Hollow Tubes
(The Eurographics Association and Blackwell Publishing Ltd, 2010)The Cosserat theory of elastic rods has been used in a wide range of application domains to model and simulate the elastic deformation of thin rods. It is physically accurate and its implementations are efficient for ... -
Geometry-Driven Local Neighbourhood Based Predictors for Dynamic Mesh Compression
(The Eurographics Association and Blackwell Publishing Ltd, 2010) -
Guest Editorial
(The Eurographics Association and Blackwell Publishing Ltd, 2010) -
Hierarchical Structure Recovery of Point-Sampled Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We focus on the class of regular models defined by Varady et al. for reverse engineering purposes. Given a 3D surface represented through a dense set of points, we present a novel algorithm that converts to a hierarchical ... -
Letters to the Editors

Measuring Complexity in Lagrangian and Eulerian Flow Descriptions
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Automatic detection of relevant structures in scientific data sets is still one of the big challenges in visualization. Techniques based on information theory have shown to be a promising direction to automatically highlight ... -
New EUROGRAPHICS Fellows
(The Eurographics Association and Blackwell Publishing Ltd, 2010) -
Optical Image Processing Using Light Modulation Displays
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We propose to enhance the capabilities of the human visual system by performing optical image processing directly on an observed scene. Unlike previous work which additively superimposes imagery on a scene, or completely ... -
Over Two Decades of Integration-Based, Geometric Flow Visualization
(The Eurographics Association and Blackwell Publishing Ltd, 2010)With ever increasing computing power, it is possible to process ever more complex fluid simulations. However, a gap between data set sizes and our ability to visualize them remains. This is especially true for the field ... -
Poisson-Based Weight Reduction of Animated Meshes
(The Eurographics Association and Blackwell Publishing Ltd, 2010)While animation using barycentric coordinates or other automatic weight assignment methods has become a popular method for shape deformation, the global nature of the weights limits their use for real-time applications. ... -
Reducing Plenoptic Camera Artifacts
(The Eurographics Association and Blackwell Publishing Ltd, 2010)The focused plenoptic camera differs from the traditional plenoptic camera in that its microlenses are focused on the photographed object rather than at infinity. The spatio-angular tradeoffs available with this approach ... -
Resampling Strategies for Deforming MLS Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Moving-least-squares (MLS) surfaces undergoing large deformations need periodic regeneration of the point set (point-set resampling) so as to keep the point-set density quasi-uniform. Previous work by the authors dealt ...
