Abstract

We present two new vortex-summarization techniques designed to portray vortex motion over an entire simulation and over an ensemble of simulations in a single image. Linear “vortex core timelines” with cone glyphs summarize flow over all time steps of a single simulation, with color varying to indicate time. Simplified “ribbon summarizations” with hue nominally encoding ensemble membership and saturation encoding time enable direct visual comparison of the distribution of vortices in time and space for a set of simulations.
