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 ...
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 ...
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 ...
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 ...
Trajectory Density Projection for Vector Field Visualization
(The Eurographics Association, 2013)
Trajectory visualization is an important tool to capture intrinsic characteristics of vector fields. However, often this class of geometric visualization suffers from visual clutter due to the number of curves that occlude ...
Inertial Steady 2D Vector Field Topology
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Vector field topology is a powerful and matured tool for the study of the asymptotic behavior of tracer particles in steady flows. Yet, it does not capture the behavior of finite-sized particles, because they develop inertia ...
MCFTLE: Monte Carlo Rendering of Finite-Time Lyapunov Exponent Fields
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Traditionally, Lagrangian fields such as finite-time Lyapunov exponents (FTLE) are precomputed on a discrete grid and are ray casted afterwards. This, however, introduces both grid discretization errors and sampling errors ...
Finite-Time Mass Separation for Comparative Visualizations of Inertial Particles
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
The visual analysis of flows with inertial particle trajectories is a challenging problem because time-dependent particle trajectories additionally depend on mass, which gives rise to an infinite number of possible ...
