Abstract / Description:We describe an approach to visually analyzing the dynamic behavior of 3D
time-dependent flow fields by considering the behavior of the path lines. At
selected positions in the 4D space-time domain, we compute a number of local
and global properties of path lines describing relevant features of them. The
resulting multivariate data set is analyzed by applying state-of-the-art
information
visualization approaches in the sense of a set of linked views (scatter
plots, parallel coordinates, etc.) with interactive brushing and focus+context
visualization. The selected path lines with certain properties are integrated
and visualized as colored 3D curves. This approach allows an interactive
exploration
of intricate 4D flow structures. We apply our method to a number
of flow data sets and describe how path line attributes are used for describing
characteristic features of these flows.
