Topology-Based Visualization of Time-Dependent 2D Vector Fields
(The Eurographics Association, 2001)
Topology-based methods have been successfully applied to the visualization of instantaneous planar vector fields. In this paper, we present the topology-based visualization of time-dependent 2D flows. Our method tracks ...
Vector and Tensor Field Topology Simplification on Irregular Grids
(The Eurographics Association, 2001)
Topology-based visualization of planar turbulent flows results in visual clutter due to the presence of numerous features of very small scale. In this paper, we attack this problem with a topology simplification method for ...
Surface Techniques for Vortex Visualization
(The Eurographics Association, 2004)
This paper presents powerful surface based techniques for the analysis of complex flow fields resulting from CFD simulations. Emphasis is put on the examination of vortical structures. An improved method for stream surface ...
Lagrangian Visualization of Flow-Embedded Surface Structures
(The Eurographics Association and Blackwell Publishing Ltd., 2008)
The notions of Finite-Time Lyapunov Exponent (FTLE) and Lagrangian Coherent Structures provide a strong framework for the analysis and visualization of complex technical flows. Their definition is simple and intuitive, and ...
Automatic Detection and Visualization of Distinctive Structures in 3D Unsteady Multi-fields
(The Eurographics Association and Blackwell Publishing Ltd., 2008)
Current unsteady multi-field simulation data-sets consist of millions of data-points. To efficiently reduce this enormous amount of information, local statistical complexity was recently introduced as a method that identifies ...
