Research efforts have been devoted to extraction and visualization of vortices in an unsteady (turbulent) flow. Characterizing the behaviors of the flow, vortices are identifiable as regions using a vortex detector known as the lambda2-criterion. Isosurface visualization renders vortex regions based on a chosen isovalue. However, it is highly challenging to choose one isovalue suitable for visualizing...
Visualization of flow features, such as vortices, aids in analyzing complex unsteady (turbulent) flows and thus facilitate human cognition of flow phenomena. Typical data of unsteady flows are vector fields of velocity in four spatiotemporal dimensions (4D). Often empirical data of unsteady flows suffer from unknown measurement errors (i.e., undesired vectors). The undesired vectors lead to clutter...
