Improved Sparse Seeding for 3D Electrostatic Field Lines
(The Eurographics Association, 2015)
We present an improved seeding strategy for sparse visualization of electrostatic fields. By analyzing the curvature of the field lines, we extract points of extremal field strength between charges of different sign and ...
MVN-Reduce: Dimensionality Reduction for the Visual Analysis of Multivariate Networks
(The Eurographics Association, 2017)
The analysis of Multivariate Networks (MVNs) can be approached from two different perspectives: a multidimensional one, consisting of the nodes and their multiple attributes, or a relational one, consisting of the network's ...
Total Euler Characteristic as a Noise Measure to aid Transfer Function Design
(The Eurographics Association, 2013)
For image-based, semi- or fully automated design of transfer functions for direct volume rendering, it is beneficial to have an estimation of the noise level in the rendered image. A topology-motivated noise measure is ...
Space Bundling for Continuous Parallel Coordinates
(The Eurographics Association, 2016)
Continuous Parallel Coordinates (CPC) are a visualization technique used to perform multivariate analysis of different scalar fields defined on the same domain. While classic Parallel Coordinates draws a line for each ...
Marching Pentatopes for Continuous Morphing of Isosurfaces From Four Dimensional Data in HTML5/WebGL
(The Eurographics Association, 2017)
Animations which show three dimensional volumes continuously changing over time facilitate the exploration and analysis of complex data sets such as calcium image data of neural activity and phase contrast magnetic resonance ...
On Establishing Visualization Requirements: A Case Study in Product Costing
(The Eurographics Association, 2017)
The process of identifying visualization requirements is an important part of every visualization researcher's and practitioner's job. Nevertheless, the scientific literature is rather sparse on this topic, usually resorting ...
Visualizing Contour Distributions in 2D Ensemble Data
(The Eurographics Association, 2013)
Overlaid plots of iso-contours in individual members of a scalar ensemble field are a popular concept to visualize the data uncertainty. However, such plots do not allow inferring on the spatial cumulative probability ...
Spiral Theme Plot
(The Eurographics Association, 2016)
We introduce a new visualization method for temporal data, Spiral Theme Plot, by combining ThemeRiver method, spiral patterns, and scatter plot technique. Similar to ThemeRiver, data in different categories (themes) are ...
Time-Ray Maps: Visualization of Spatial and Temporal Evolution of News Stories
(The Eurographics Association, 2017)
Time-Ray maps (see Figure 1) are designed to represent the temporal and spatial evolution of the reporting of a single news story. The visualization presents a compact representation that tells the story of the story in ...
A Quality-Preserving Cartesian to Body-Centered Cubic Downsampling Transform
(The Eurographics Association, 2015)
The body-centered cubic lattice is the optimal sampling lattice in three dimensions. However, most volumetric datasets are acquired on the well-known Cartesian cubic lattice. In order to leverage the approximation capabilities ...
