(a) LIC images at 3 different time slices. (b) Tracking the locations of critical points as
stream lines (red/blue/yellow); local
bifurcations: Hopf bifurcations (green
spheres), fold bifurcations (gray spheres).
(c) Global bifurcations: saddle connections
(red/blue flow ribbons), tracked closed stream
lines (green surfaces).

Topological methods aim at the segmentation of a vector field into
