Selecting Coherent and Relevant Plots in Large Scatterplot Matrices
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
The scatterplot matrix (SPLOM) is a well‐established technique to visually explore high‐dimensional data sets. It is characterized by the number of scatterplots (plots) of which it consists of. Unfortunately, this number ...
Decoupled Opacity Optimization for Points, Lines and Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Displaying geometry in flow visualization is often accompanied by occlusion problems, making it difficult to perceive information that is relevant in the respective application. In a recent technique, named opacity ...
Linear Discriminative Star Coordinates for Exploring Class and Cluster Separation of High Dimensional Data
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
One main task for domain experts in analysing their nD data is to detect and interpret class/cluster separations and outliers. In fact, an important question is, which features/dimensions separate classes best or allow a ...
The State of the Art in Topology‐Based Visualization of Unsteady Flow
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Vector fields are a common concept for the representation of many different kinds of flow phenomena in science and engineering. Methods based on vector field topology are known for their convenience for visualizing and ...
Opacity Optimization for Surfaces
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
In flow visualization, integral surfaces rapidly tend to expand, fold and produce vast amounts of occlusion. While silhouette enhancements and local transparency mappings proved useful for semi-transparent depictions, they ...
Global Selection of Stream Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Stream surfaces are well-known and widely-used structures for 3D flow visualization. A single surface can be sufficient to represent important global flow characteristics. Unfortunately, due to the huge space of possible ...
Uncertain 2D Vector Field Topology
(The Eurographics Association and Blackwell Publishing Ltd, 2010)
We introduce an approach to visualize stationary 2D vector fields with global uncertainty obtained by considering the transport of local uncertainty in the flow. For this, we extend the concept of vector field topology to ...
Hierarchical Opacity Optimization for Sets of 3D Line Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Abstract The selection of meaningful lines for 3D line data visualization has been intensively researched in recent years. Most approaches focus on single line fields where one line passes through each domain point. This ...
Advected Tangent Curves: A General Scheme for Characteristic Curves of Flow Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
We present the first general scheme to describe all four types of characteristic curves of flow fields - stream, path, streak, and time lines - as tangent curves of a derived vector field. Thus, all these lines can be ...
General Projective Maps for Multidimensional Data Projection
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
To project high-dimensional data to a 2D domain, there are two well-established classes of approaches: RadViz and Star Coordinates. Both are well-explored in terms of accuracy, completeness, distortions, and interaction ...
