Figure 1 : Flow behind a circular cylinder. Shown are vortex core lines in a certain frame of reference. Their evolution over time is tracked by our algorithm and depicted using transparent surfaces. Red color encodes the past while gray shows the future. ABSTRACT We introduce an approach to tracking vortex core lines in timedependent 3D flow fields which are defined by the parallel vectors approach. They build surface structures in the 4D space-time domain. To extract them, we introduce two 4Ddoi:10.1109/vis.2005.36 fatcat:t6qirzpnyfdabczqq77x3djjuq
