Improved Sparse Seeding for 3D Electrostatic Field Lines
(The Eurographics Association, 2015)
We present an improved seeding strategy for sparse visualization of electrostatic fields. By analyzing the curvature of the field lines, we extract points of extremal field strength between charges of different sign and ...
Local Extraction of Bifurcation Lines
(The Eurographics Association, 2013)
We present local extraction of bifurcation lines together with extraction of their manifolds, a topological feature that has not yet been sufficiently recognized in scientific visualization. The bifurcation lines are ...
Visualizing Solar Dynamics Data
(The Eurographics Association, 2012)
Solar dynamics data, particularly those from the Solar Dynamics Observatory, are now available in a sheer volume that is hard to investigate with traditional visualization tools, which mainly display 2D images. While the ...
Visualization of 2DWave Propagation by Huygens' Principle
(The Eurographics Association, 2015)
We present a novel technique to visualize wave propagation in 2D scalar fields. Direct visualization of wave fronts is susceptible to visual clutter and interpretation difficulties due to space-time interference and global ...
Space-Time Bifurcation Lines for Extraction of 2D Lagrangian Coherent Structures
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We present a novel and efficient technique to extract Lagrangian coherent structures in two-dimensional time-dependent vector fields. We show that this can be achieved by employing bifurcation line extraction in the ...
