Illustrative Multivariate Visualization for Geological Modelling
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper, we present a novel illustrative multivariate visualization for geological modelling to assist geologists and reservoir engineers in visualizing multivariate datasets in superimposed representations, in ... -
Interactive Analysis of Word Vector Embeddings
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Word vector embeddings are an emerging tool for natural language processing. They have proven beneficial for a wide variety of language processing tasks. Their utility stems from the ability to encode word relationships ... -
Interactive Investigation of Traffic Congestion on Fat-Tree Networks Using TREESCOPE
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Parallel simulation codes often suffer from performance bottlenecks due to network congestion, leaving millions of dollars of investments underutilized. Given a network topology, it is critical to understand how different ... -
Interactive Visual Exploration of Local Patterns in Large Scatterplot Spaces
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Analysts often use visualisation techniques like a scatterplot matrix (SPLOM) to explore multivariate datasets. The scatterplots of a SPLOM can help to identify and compare two-dimensional global patterns. However, local ... -
Key Time Steps Selection for Large-Scale Time-Varying Volume Datasets Using an Information-Theoretic Storyboard
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Key time steps selection is essential for effective and efficient scientific visualization of large-scale time-varying datasets. We present a novel approach that can decide the number of most representative time steps while ... -
Landscaper: A Modeling System for 3D Printing Scale Models of Landscapes
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Landscape models of geospatial regions provide an intuitive mechanism for exploring complex geospatial information. However, the methods currently used to create these scale models require a large amount of resources, which ... -
Maps and Globes in Virtual Reality
(The Eurographics Association and John Wiley & Sons Ltd., 2018)This paper explores different ways to render world-wide geographic maps in virtual reality (VR). We compare: (a) a 3D exocentric globe, where the user's viewpoint is outside the globe; (b) a flat map (rendered to a plane ... -
Multiscale Visualization and Exploration of Large Bipartite Graphs
(The Eurographics Association and John Wiley & Sons Ltd., 2018)A bipartite graph is a powerful abstraction for modeling relationships between two collections. Visualizations of bipartite graphs allow users to understand the mutual relationships between the elements in the two collections, ... -
The Perception of Graph Properties in Graph Layouts
(The Eurographics Association and John Wiley & Sons Ltd., 2018)When looking at drawings of graphs, questions about graph density, community structures, local clustering and other graph properties may be of critical importance for analysis. While graph layout algorithms have focused ... -
PixelSNE: Pixel-Aligned Stochastic Neighbor Embedding for Efficient 2D Visualization with Screen-Resolution Precision
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Embedding and visualizing large-scale high-dimensional data in a two-dimensional space is an important problem, because such visualization can reveal deep insights of complex data. However, most of the existing embedding ... -
Rendering and Extracting Extremal Features in 3D Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Visualizing and extracting three-dimensional features is important for many computational science applications, each with their own feature definitions and data types. While some are simple to state and implement (e.g. ... -
Representative Consensus from Limited-Size Ensembles
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Characterizing the uncertainty and extracting reliable visual information from ensemble data have been persistent challenges in various disciplines, specifically in simulation sciences. Many ensemble analysis and visualization ... -
SetCoLa: High-Level Constraints for Graph Layout
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Constraints enable flexible graph layout by combining the ease of automatic layout with customizations for a particular domain. However, constraint-based layout often requires many individual constraints defined over ... -
Spatio-Temporal Contours from Deep Volume Raycasting
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We visualize contours for spatio-temporal processes to indicate where and when non-continuous changes occur or spatial bounds are encountered. All time steps are comprised densely in one visualization, with contours allowing ... -
ThreadReconstructor: Modeling Reply-Chains to Untangle Conversational Text through Visual Analytics
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present ThreadReconstructor, a visual analytics approach for detecting and analyzing the implicit conversational structure of discussions, e.g., in political debates and forums. Our work is motivated by the need to ... -
Time Lattice: A Data Structure for the Interactive Visual Analysis of Large Time Series
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Advances in technology coupled with the availability of low-cost sensors have resulted in the continuous generation of large time series from several sources. In order to visually explore and compare these time series at ... -
