M. Jiang, R. Machiraju, and D. Thompson, "A Novel Approach to Vortex Core Region Detection," Joint Eurographics-IEEE TCVG Symposium on Visualization, Barcelona, Spain, May 2002, pp. 217-225.
In this paper we present a simple and efficient vortex core region detection algorithm based on ideas derived from combinatorial topology. These ideas originated from Sperner s lemma, which by itself is of little value to detecting vortex cores. However, we take these ideas from the lemma and apply them in a point-based fashion to detecting vortex core regions. The resulting algorithms for both 2D and 3D are quite simple and very efficient compared to existing ones. We applied our algorithms to both numerically simulated and procedurally generated datasets to illustrate the efficacy of our approach.
