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 ... -
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. ... -
Visualizing the Phase Space of Heterogeneous Inertial Particles in 2D Flows
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In many scientific disciplines, the motion of finite-sized objects in fluid flows plays an important role, such as in brownout engineering, sediment transport, oceanology or meteorology. These finite-sized objects are ... -
ChangeCatcher: Increasing Inter-author Awareness for Visualization Development
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We introduce an approach for explicitly revealing changes between versions of a visualization workbook to support version comparison tasks. Visualization authors may need to understand version changes for a variety of ... -
Baseball Timeline: Summarizing Baseball Plays Into a Static Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In sports, Play Diagrams are the standard way to represent and convey information. They are widely used by coaches, managers, journalists and fans in general. There are situations where diagrams may be hard to understand, ... -
Fast and Accurate CNN-based Brushing in Scatterplots
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Brushing plays a central role in most modern visual analytics solutions and effective and efficient techniques for data selection are key to establishing a successful human-computer dialogue. With this paper, we address ... -
Explorative Blood Flow Visualization using Dynamic Line Filtering based on Surface Features
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Rupture risk assessment is a key to devise patient-specific treatment plans of cerebral aneurysms. To understand and predict the development of aneurysms and other vascular diseases over time, both hemodynamic flow patterns ... -
Exploring High-Dimensional Structure via Axis-Aligned Decomposition of Linear Projections
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Two-dimensional embeddings remain the dominant approach to visualize high dimensional data. The choice of embeddings ranges from highly non-linear ones, which can capture complex relationships but are difficult to interpret ... -
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 ... -
Visual and Quantitative Analysis of Great Arteries' Blood Flow Jets in Cardiac 4D PC-MRI Data
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Flow in the great arteries (aorta, pulmonary artery) is normally laminar with a parabolic velocity profile. Eccentric flow jets are linked to various diseases like aneurysms. Cardiac 4D PC-MRI data provide spatio-temporally ... -
Exploring the Visualization Design Space with Repertory Grids
(The Eurographics Association and John Wiley & Sons Ltd., 2018)There is an ongoing discussion in the visualization community about the relevant factors that render a visualization effective, expressive, memorable, aesthetically pleasing, etc. These factors lead to a large design space ... -
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 ... -
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 ... -
Chart Constellations: Effective Chart Summarization for Collaborative and Multi-User Analyses
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Many data problems in the real world are complex and require multiple analysts working together to uncover embedded insights by creating chart-driven data stories. How, as a subsequent analysis step, do we interpret and ... -
Cosine-Weighted B-Spline Interpolation on the Face-Centered Cubic Lattice
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Cosine-Weighted B-spline (CWB) interpolation [Csé13] has been originally proposed for volumetric data sampled on the Body-Centered Cubic (BCC) lattice. The BCC lattice is well known to be optimal for sampling isotropically ... -
