Direct Visualization of Particle-Partition of Unity Data
(The Eurographics Association, 2011)
Direct visualization of higher-order data provides manifold advantages over the traditional approach, which is based on resampling and subsequent visualization by interpolation-based techniques. Most important, it avoids ...
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 ...
Toward Wall Function Consistent Interpolation of Flow Fields
(The Eurographics Association, 2013)
In this paper we provide a first step toward simulation-consistent visualization techniques. We focus on wall functions modeling near-wall flow in computational fluid dynamics (CFD) using the law of the wall. By integrating ...
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 ...
FTLE Computation Beyond First-Order Approximation
(The Eurographics Association, 2012)
We present a framework for different approaches to finite-time Lyapunov exponent (FTLE) computation for 2D vector fields, based on the advection of seeding circles. On the one hand it unifies the popular flow map approach ...
Visualization of Advection-Diffusion in Unsteady Fluid Flow
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Advection has been the standard transport mechanism in flow visualization. Diffusion, in contrast, has not been considered important in visual flow field analysis so far, although it is inherent to many physical processes. ...
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 ...
Photoelasticity Raycasting
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present a novel physically-based method to visualize stress tensor fields. By incorporating photoelasticity into traditional raycasting and extending it with reflection and refraction, taking into account polarization, ...
