The goal of topology-based visualization of scalar fields is to
automatically locate parameter-free, intrinsic features of the data. In
the case of scalar fields, ridge-valley structures can be extracted
according to several definitions. For vector fields, the topological
analysis starts with the extraction of critical points. Critical points
are useful for controlling the seeding of streamlines or particles, and
the critical type classification and the local inspection of critical
points gives a good overview over a dataset. Based on critical points,
the set of separatrices yields a partical segmentation of the vector
field into regions of similar behavior. The extension of
topology-based visualization methods to time-dependent vector fields
is a current focus of our research.
