Vector Field Topology Visualization Research at NAS

History
Topology research at the NAS Research Branch began when Creon Levit developed
two interactive programs to interactively investigate critical points (zeros in
a vector field) and associated stable and unstable manifolds in 2D and 3D
analytic vector fields.
The branch subsequently funded Jim Helman and Bert Hessilink's work in vector
field topology visualization resulting in the papers:
- "Surface Representation of Two- and Three-Dimensional Fluid Flow Topology,"
(abstract)
Proc. Visualization '90, San Francisco, IEEE Computer Society Press (1990),
which won best paper,
- Analysis and Representation of Complex Structures in Separated Flows,"
(abstract)
SPIE Conference on Extracting Meaning From Complex Data, San Jose, (1991)
- "Representiation and Display of Vector Field Topology in Fluid Flow Data Sets,"
IEEE Computer, pp. 27-36, Aug. 1989.
The paper A Tool for Visualizing the Topology of Three-Dimensional Vector Fields
by A. Globus, C. Levit, and T. Lasinski was presented at Visualization '91
(abstract)
(pictures).
This paper describes a
FAST (Flow Analysis Software Toolkit) module
the visualize that visualizes the topology of flows on curvilinear and
multizone, iblank grids.
This work contributed topology visualization available in a general purpose visualization
system, display of the off-surface eigenvector of surface critical points, and
location and display of vortex cores.
In 1992 and 1993, D. Asimov, A. Globus, and C. Levit gave vector field topology
tutorials at the Vis' conferences. From this work you can examine:
