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 ...
Towards Glyphs for Uncertain Symmetric Second-Order Tensors
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Measured data often incorporates some amount of uncertainty, which is generally modeled as a distribution of possible samples. In this paper, we consider second-order symmetric tensors with uncertainty. In the 3D case, ...
Static Visualization of Unsteady Flows by Flow Steadification
(The Eurographics Association, 2020)
Finding static visual representations of time-varying phenomena is a standard problem in visualization. We are interested in unsteady flow data, i.e., we want to find a static visualization - one single still image - that ...
The Parallel Eigenvectors Operator
(The Eurographics Association, 2018)
The parallel vectors operator is a prominent tool in visualization that has been used for line feature extraction in a variety of applications such as ridge and valley lines, separation and attachment lines, and vortex ...

Uncertain Stream Lines
(The Eurographics Association, 2023)
We present a new approach for the visual representation of uncertain stream lines in vector field ensembles. While existing approaches rely on a particular seed point for the analysis of uncertain streamlines, our approach ...
Autonomous Particles for In-Situ-Friendly Flow Map Sampling
(The Eurographics Association, 2023)
Computing and storing flow maps is a common approach to processing and analyzing large flow simulations in a Lagrangian way. Accurate Lagrangian-based visualizations require a good sampling of the flow map. We present an ...
OptFlowCam: A 3D-Image-Flow-Based Metric in Camera Space for Camera Paths in Scenes with Extreme Scale Variations
(The Eurographics Association and John Wiley & Sons Ltd., 2024)
Interpolation between camera positions is a standard problem in computer graphics and can be considered the foundation of camera path planning. As the basis for a new interpolation method, we introduce a new Riemannian ...
