Abstract

An essential part of visualization of massive time-dependent data sets is to identify, quantify and track important regions and structures (objects of interest). This is true for almost all disciplines since the crux of understanding the original simulation, experiment or observation is the study of the evolution of the 'objects' present. Some well known examples include tracking the progression of a storm, the motion and change of the 'ozone hole', or the movement of vortices shed by the meandering Gulf stream. In this paper, we describe work-in- progress on extracting and tracking three dimensional evolving objects in time dependent simulations. The simulations are from ongoing research in computational fluid dynamics (CFD), however, the tracking procedures are general and are appropriate for many other disciplines.
