Interactive Computation and Rendering of Finite-Time Lyapunov Exponent Fields
Found in: IEEE Transactions on Visualization and Computer Graphics
By Samer Barakat,C. Garth,X. Tricoche
Issue Date:August 2012
pp. 1368-1380
In this paper, we present a novel technique that allows for the coupled computation and visualization of salient flow structures at interactive frame rates. Our approach is built upon a hierarchical representation of the Finite-time Lyapunov Exponent (FTLE...
 
Cubic Gradient-Based Material Interfaces
Found in: IEEE Transactions on Visualization and Computer Graphics
By I. Prilepov,H. Obermaier,E. Deines,C. Garth,K. I. Joy
Issue Date:October 2013
pp. 1687-1699
Multifluid simulations often create volume fraction data, representing fluid volumes per region or cell of a fluid data set. Accurate and visually realistic extraction of fluid boundaries is a challenging and essential task for efficient analysis of multif...
 
Visualization and Analysis of Vortex-Turbine Intersections in Wind Farms
Found in: IEEE Transactions on Visualization and Computer Graphics
By S. Shafii,H. Obermaier,R. Linn, Eunmo Koo,M. Hlawitschka,C. Garth,B. Hamann,K. I. Joy
Issue Date:September 2013
pp. 1579-1591
Characterizing the interplay between the vortices and forces acting on a wind turbine's blades in a qualitative and quantitative way holds the potential for significantly improving large wind turbine design. This paper introduces an integrated pipeline for...
 
Analysis of Time-Dependent Flow-Sensitive PC-MRI Data
Found in: IEEE Transactions on Visualization and Computer Graphics
By H. Krishnan,C. Garth,J. Guhring,M. A. Gulsun,A. Greiser,K. I. Joy
Issue Date:June 2012
pp. 966-977
Many flow visualization techniques, especially integration-based methods, are problematic when the measured data exhibit noise and discretization issues. Particularly, this is the case for flow-sensitive phase-contrast magnetic resonance imaging (PC-MRI) d...

Moment Invariants for the Analysis of 2D Flow Fields
Found in: IEEE Transactions on Visualization and Computer Graphics
By M. Schlemmer,M. Heringer,F. Morr,I. Hotz,M.-H. Bertram,C. Garth,W. Kollmann,B. Hamann,H. Hagen
Issue Date:November 2007
pp. 1743-1750
We present a novel approach for analyzing two-dimensional (2D) flow field data based on the idea of invariant moments. Moment invariants have traditionally been used in computer vision applications, and we have adapted them for the purpose of interactive e...
 
Efficient Computation and Visualization of Coherent Structures in Fluid Flow Applications
Found in: IEEE Transactions on Visualization and Computer Graphics
By C. Garth,F. Gerhardt,X. Tricoche,H. Hagen
Issue Date:November 2007
pp. 1464-1471
The recently introduced notion of Finite-Time Lyapunov Exponent to characterize Coherent Lagrangian Structures provides a powerful framework for the visualization and analysis of complex technical flows. Its definition is simple and intuitive, and it has a...
 
Listener-based Analysis of Surface Importance for Acoustic Metrics
Found in: IEEE Transactions on Visualization and Computer Graphics
By F. Michel,E. Deines,M. Hering-Bertram,C. Garth,H. Hagen
Issue Date:November 2007
pp. 1680-1687
Acoustic quality in room acoustics is measured by well defined quantities, like definition, which can be derived from simulated impulse response filters or measured values. These take into account the intensity and phase shift of multiple reflections due t...
