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 ...
Bilateral Depth Filtering for Enhanced Vessel Reformation
(The Eurographics Association, 2014)
Curved Planar Reformation is a powerful visualization technique for the diagnosis of vascular diseases. It allowsan accurate centerline-driven investigation of vessel lumen while providing valuable anatomical context.Extended ...
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 ...
Per-Fragment Image-based Flow Visualization using Interactive Surface Extraction from Unstructured Grids
(The Eurographics Association, 2014)
We present a method for image-based visualization of flow fields on unstructured grids. For interactive explorationof flow data from CFD simulations, we combine GPU-accelerated surface extraction methods and line ...
OceanPaths: Visualizing Multivariate Oceanography Data
(The Eurographics Association, 2015)
Geographical datasets are ubiquitous in oceanography. While map-based visualizations are useful for many different domains, they can suffer from cluttering and overplotting issues when used for multivariate data sets. As ...
