Tablorer - An Interactive Tree Visualization System for Tablet PCs
(The Eurographics Association and Blackwell Publishing Ltd., 2011)A variety of mobile devices are available today, but there is no dominant tree visualization system in the devices. This paper proposes Tablorer, a novel interactive tree visualization system for medium-sized mobile devices, ... -
In-situ Sampling of a Large-Scale Particle Simulation for Interactive Visualization and Analysis
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We describe a simulation-time random sampling of a large-scale particle simulation, the RoadRunner Universe MC3 cosmological simulation, for interactive post-analysis and visualization. Simulation data generation rates ... -
Visualizing the Evolution of Community Structures in Dynamic Social Networks
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Social network analysis is the study of patterns of interaction between social entities. The field is attracting increasing attention from diverse disciplines including sociology, epidemiology, and behavioral ecology. An ... -
Visual Recommendations for Network Navigation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Understanding large, complex networks is important for many critical tasks, including decision making, process optimization, and threat detection. Existing network analysis tools often lack intuitive interfaces to support ... -
ImPrEd: An Improved Force-Directed Algorithm that Prevents Nodes from Crossing Edges
(The Eurographics Association and Blackwell Publishing Ltd., 2011)PrEd [Ber00] is a force-directed algorithm that improves the existing layout of a graph while preserving its edge crossing properties. The algorithm has a number of applications including: improving the layouts of planar ... -
A Gradient-Based Comparison Measure for Visual analysis of Multifield Data
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We introduce a multifield comparison measure for scalar fields that helps in studying relations between them. The comparison measure is insensitive to noise in the scalar fields and to noise in their gradients. Further, ... -
Pathway Preserving Representation of Metabolic Networks
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Improvements in biological data acquisition and genomes sequencing now allow to reconstruct entire metabolic networks of many living organisms. The size and complexity of these networks prohibit manual drawing and thereby ... -
Uncertainty-Aware Exploration of Continuous Parameter Spaces Using Multivariate Prediction
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Systems projecting a continuous n-dimensional parameter space to a continuous m-dimensional target space play an important role in science and engineering. If evaluating the system is expensive, however, an analysis is ... -
Structural Decomposition Trees
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Researchers and analysts in modern industrial and academic environments are faced with a daunting amount of multi-dimensional data. While there has been significant development in the areas of data mining and knowledge ... -
Temporal Visualization of Boundary-based Geo-information Using Radial Projection
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This work is concerned with a design study by an interdisciplinary team on visualizing a 10-year record of seasonal and inter-annual changes in frontal position (advance/retreat) of nearly 200 marine terminating glaciers ... -
Visualization of Time-Series Data in Parameter Space for Understanding Facial Dynamics
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Over the past decade, computer scientists and psychologists have made great efforts to collect and analyze facial dynamics data that exhibit different expressions and emotions. Such data is commonly captured as videos and ... -
Visualizing the Positional and Geometrical Variability of Isosurfaces in Uncertain Scalar Fields
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a novel approach for visualizing the positional and geometrical variability of isosurfaces in uncertain 3D scalar fields. Our approach extends recent work by Pöthkow and Hege [PH10] in that it accounts for ... -
Fast Extraction of High-quality Crease Surfaces for Visual Analysis
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a novel algorithm for the efficient extraction and visualization of high-quality ridge and valley surfaces from numerical datasets. Despite their rapidly increasing popularity in visualization, these so-called ... -
Assisted Descriptor Selection Based on Visual Comparative Data Analysis
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Exploration and selection of data descriptors representing objects using a set of features are important components in many data analysis tasks. Usually, for a given dataset, an optimal data description does not exist, as ...
