Mandatory Critical Points of 2D Uncertain Scalar Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2014)This paper introduces a novel, non-local characterization of critical points and their global relation in 2D uncertain scalar fields. The characterization is based on the analysis of the support of the probability density ... -
Many Plans: Multidimensional Ensembles for Visual Decision Support in Flood Management
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Uncertainties in flood predictions complicate the planning of mitigation measures. There is a consensus that many possible incident scenarios should be considered. For each scenario, a specific response plan should be ... -
Methods for Compensating Contrast Effects in Information Visualization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Color, as one of the most effective visual variables, is used in many techniques to encode and group data points according to different features. Relations between features and groups appear as visual patterns in the ... -
Metro Transit-Centric Visualization for City Tour Planning
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In general, city trip planning consists of two main steps: knowing Points-Of-Interest (POIs), and then planning a tour route from the current point to next preferred POIs. We mainly consider the metro for traveling around ... -
Networks of Names: Visual Exploration and Semi-Automatic Tagging of Social Networks from Newspaper Articles
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Understanding relationships between people and organizations by reading newspaper articles is difficult to manage for humans due to the large amount of data. To address this problem, we present and evaluate a new visual ... -
Opacity Optimization for Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In flow visualization, integral surfaces rapidly tend to expand, fold and produce vast amounts of occlusion. While silhouette enhancements and local transparency mappings proved useful for semi-transparent depictions, they ... -
Papilio: Visualizing Android Application Permissions
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We introduce Papilio, a new visualization technique for visualizing permissions of real-world Android applications. We explore the development of layouts that exploit the directed acyclic nature of Android application ... -
Parallel Irradiance Caching for Interactive Monte-Carlo Direct Volume Rendering
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We propose a technique to build the irradiance cache for isotropic scattering simultaneously with Monte Carlo progressive direct volume rendering on a single GPU, which allows us to achieve up to four times increased ... -
Preface and Table of Contents

RBF Volume Ray Casting on Multicore and Manycore CPUs
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Modern supercomputers enable increasingly large N-body simulations using unstructured point data. The structures implied by these points can be reconstructed implicitly. Direct volume rendering of radial basis function ... -
Semi-Automatic Editing of Graphs with Customized Layouts
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Usually visualization is applied to gain insight into data. Yet consuming the data in form of visual representation is not always enough. Instead, users need to edit the data, preferably through the same means used to ... -
Sets of Globally Optimal Stream Surfaces for Flow Visualization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Stream surfaces are a well-studied and widely used tool for the visualization of 3D flow fields. Usually, stream surface seeding is carried out manually in time-consuming trial and error procedures. Only recently automatic ... -
SimilarityExplorer: A Visual Inter-Comparison Tool for Multifaceted Climate Data
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Inter-comparison and similarity analysis to gauge consensus among multiple simulation models is a critical visualization problem for understanding climate change patterns. Climate models, specifically, Terrestrial Biosphere ... -
Sparse Representation and Visualization for Direct Numerical Simulation of Premixed Combustion
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Direct Numerical Simulations of premixed combustion produce terabytes of raw data, which are prohibitively large to be stored, and have to be analyzed and visualized. A simultaneous and integrated treatment of data storage, ... -
Stability of Dissipation Elements: A Case Study in Combustion
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Recently, dissipation elements have been gaining popularity as a mechanism for measurement of fundamental properties of turbulent flow, such as turbulence length scales and zonal partitioning. Dissipation elements segment ... -
Towards an Unbiased Comparison of CC, BCC, and FCC Lattices in Terms of Prealiasing
(The Eurographics Association and John Wiley and Sons Ltd., 2014)In the literature on optimal regular volume sampling, the Body-Centered Cubic (BCC) lattice has been proven to be optimal for sampling spherically band-limited signals above the Nyquist limit. On the other hand, if the ... -
Visual Analysis of Sets of Heterogeneous Matrices Using Projection-Based Distance Functions and Semantic Zoom
(The Eurographics Association and John Wiley and Sons Ltd., 2014)Matrix visualization is an established technique in the analysis of relational data. It is applicable to large, dense networks, where node-link representations may not be effective. Recently, domains have emerged in which ... -
Visual Analysis of Time-Series Similarities for Anomaly Detection in Sensor Networks
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a system to analyze time-series data in sensor networks. Our approach supports exploratory tasks for the comparison of univariate, geo-referenced sensor data, in particular for anomaly detection. We split the ... -
Visual Multiplexing
(The Eurographics Association and John Wiley and Sons Ltd., 2014)The majority of display devices used in visualization are 2D displays. Inevitably, it is often necessary to overlay one piece of visual information on top of another, especially in applications such as multi-field visualization ... -
Visual-interactive Exploration of Interesting Multivariate Relations in Mixed Research Data Sets
(The Eurographics Association and John Wiley and Sons Ltd., 2014)The analysis of research data plays a key role in data-driven areas of science. Varieties of mixed research data sets exist and scientists aim to derive or validate hypotheses to find undiscovered knowledge. Many analysis ...
