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 ...
Implicit Integral Surfaces
(The Eurographics Association, 2012)
We present an implicit method for globally computing all four classic types of integral surfaces - stream, path, streak, and time surfaces - in 3D time-dependent vector fields. Our novel formulation is based on the ...
A View-Dependent and Inter-Frame Coherent Visualization of Integral Lines using Screen Contribution
(The Eurographics Association, 2011)
In vector field visualization, integral lines like stream, path, or streak lines are often used to examine the behavior of steady and unsteady flows. In 3D, however, visualizing integral lines is problematic since the ...
A Clustering-based Visualization Technique to Emphasize Meaningful Regions of Vector Fields
(The Eurographics Association, 2011)
This paper proposes a vector field visualization approach that extracts and visualizes grouped regions of static 3D vector fields of similar curvature behavior. These regions are argued to ease the recognition of regions ...
Pose Correction by Space-Time Integration
(The Eurographics Association, 2011)
The deformation of a given model into different poses is an important problem in computer graphics and computer animation. In a typical workflow, a carefully designed reference surface is deformed into a couple of poses, ...
Continuous Deformations of Implicit Surfaces
(The Eurographics Association, 2010)
We introduce an approach for the continuous deformation of implicit surfaces which considers properties of all isosurfaces of a volume data set simultaneously. This is achieved by integrating divergence-free vector fields ...
Singularities of the Inertial Flow Map Gradient
(The Eurographics Association, 2016)
Inertial particles are finite-sized objects that are carried by flows, for example sand particles in air. In contrast to massless tracer particles, the trajectories of inertial particles can intersect in space-time. When ...
Finite Time Steady Vector Field Topology - Theoretical Foundation and 3D Case
(The Eurographics Association, 2017)
Vector Field Topology is the standard approach for the analysis of asymptotic particle behavior in a vector field flow: A topological skeleton is separating the flow into regions by the movement of massless particles for ...
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 ...
