Embedded Implicit Stand-Ins for Animated Meshes: A Case of Hybrid Modelling
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In this paper, we address shape modelling problems, encountered in computer animation and computer games development that are difficult to solve just using polygonal meshes. Our approach is based on a hybrid-modelling ... -
Hybrid Booleans
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In this paper, we present a novel method to compute Boolean operations on polygonal meshes. Given a Boolean expression over an arbitrary number of input meshes we reliably and efficiently compute an output mesh which ... -
Time-Dependent 2-D Vector Field Topology: An Approach Inspired by Lagrangian Coherent Structures
(The Eurographics Association and Blackwell Publishing Ltd, 2010)This paper presents an approach to a time-dependent variant of the concept of vector field topology for 2-D vector fields. Vector field topology is defined for steady vector fields and aims at discriminating the domain of ... -
SPC: Fast and Efficient Scalable Predictive Coding of Animated Meshes
(The Eurographics Association and Blackwell Publishing Ltd, 2010) -
Fast Gauss Bilateral Filtering
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In spite of high computational complexity, the bilateral filter and its modifications and extensions have recently become very popular image and shape processing tools. In this paper, we propose a fast and accurate ... -
Modelling the Appearance and Behaviour of Urban Spaces
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Urban spaces consist of a complex collection of buildings, parcels, blocks and neighbourhoods interconnected by streets. Accurately modelling both the appearance and the behaviour of dense urban spaces is a significant ... -
Meshless Shape and Motion Design for Multiple Deformable Objects
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present physically based algorithms for interactive deformable shape and motion modelling. We coarsely sample the objects with simulation nodes, and apply a meshless finite element method to obtain realistic deformations ... -
Simplifying Character Skins with Analytic Error Metrics
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Traditionally, levels of detail (LOD) for animated characters are computed from a single pose. Later techniques refined this approach by considering a set of sample poses and evaluating a more representative error metric. ... -
Evaluation of an Augmented Reality Supported Picking System Under Practical Conditions
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Order picking is one of the most important process steps in logistics. Because of their flexibility, human beings cannot be replaced by machines. But if workers, in order, picking systems are equipped with a head-mounted ... -

Topology-based Smoothing of 2D Scalar Fields with C1-Continuity
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Data sets coming from simulations or sampling of real-world phenomena often contain noise that hinders their processing and analysis. Automatic filtering and denoising can be challenging: when the nature of the noise is ... -
Multi-layer Depth Peeling by Single-Pass Hardware Rasterisation for Faster Isosurface Raytracing on a GPU
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Empty-space skipping is an essential acceleration technique for volume rendering. Image-order empty-space skipping is not well suited to GPU implementation, since it must perform checks on, essentially, a per-sample basis, ... -
Non-iterative Second-order Approximation of Signed Distance Functions for Any Isosurface Representation
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Signed distance functions (SDF) to explicit or implicit surface representations are intensively used in various computer graphics and visualization algorithms. Among others, they are applied to optimize collision detection, ... -
Visualization and Analysis-Oriented Reconstruction of Material Interfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Reconstructing boundaries along material interfaces from volume fractions is a difficult problem, especially because the under-resolved nature of the input data allows for many correct interpretations. Worse, algorithms ... -
A Salience-based Quality Metric for Visualization
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Salience detection is a principle mechanism to facilitate visual attention. A good visualization guides the observer s attention to the relevant aspects of the representation. Hence, the distribution of salience over a ... -
Understanding Interactive Legends: a Comparative Evaluation with Standard Widgets
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Interactive information visualization systems rely on widgets to allow users to interact with the data and modify the representation. We define interactive legends as a class of controls combining the visual representation ... -
The Readability of Path-Preserving Clusterings of Graphs
(The Eurographics Association and Blackwell Publishing Ltd., 2010)Graph visualization systems often exploit opaque metanodes to reduce visual clutter and improve the readability of large graphs. This filtering can be done in a path-preserving way based on attribute values associated with ... -
The Perception of Correlation in Scatterplots
(The Eurographics Association and Blackwell Publishing Ltd., 2010) -
Toward a Lagrangian Vector Field Topology
(The Eurographics Association and Blackwell Publishing Ltd., 2010)In this paper we present an extended critical point concept which allows us to apply vector field topology in the case of unsteady flow.We propose a measure for unsteadiness which describes the rate of change of the ...
