Topological Construction and Visualization of Higher Order 3D Vector Fields
(The Eurographics Association and Blackwell Publishing, Inc, 2004)
We present the first algorithm for constructing 3D vector fields based on their topological skeleton. The skeleton itself is modeled by interactively moving a number of control polygons. Then a piecewise linear vector field ...
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 ...
An Approximate Parallel Vectors Operator for Multiple Vector Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
The Parallel Vectors (PV) Operator extracts the locations of points where two vector fields are parallel. In general, these features are line structures. The PV operator has been used successfully for a variety of problems, ...
Core Lines in 3D Second-Order Tensor Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Vortices are important features in vector fields that show a swirling behavior around a common core. The concept of a vortex core line describes the center of this swirling behavior. In this work, we examine the extension ...
The State of the Art in Vortex Extraction
(© 2018 The Eurographics Association and John Wiley & Sons Ltd., 2018)
Vortices are commonly understood as rotating motions in fluid flows. The analysis of vortices plays an important role in numerous scientific applications, such as in engineering, meteorology, oceanology, medicine and many ...
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 ...
An Enhanced Spring Model for Information Visualization
(Blackwell Publishers Ltd and the Eurographics Association, 1998)
In this paper we present a new technique for visualizing multidimensional information. We describe objects of a higher dimensional information space as small closed free-form-surfaces in the visualization. The location, ...
Exact Isosurfaces for Marching Cubes
(Blackwell Publishers Ltd and the Eurographics Association, 2002)
In this paper we study the exact contours of a piecewise trilinear scalar field. We show how to represent these contours exactly as trimmed surfaces of triangular rational cubic Bezier patches. As part of this, we introduce ...
