Hierarchical Vorticity Skeletons

Sebastian Eberhardt, Steffen Weissmann, Ulrich Pinkall, Nils Thuerey We propose a novel method to extract hierarchies of vortex filaments from given three-dimensional flow velocity fields. We call these collections of filaments Hierarchical Vorticity Skeletons (HVS). They extract multi-scale information from the input velocity field, which is not possible with any previous filament extraction approach. Once computed, these HVSs […]
