Geometric flow visualization techniques for CFD simulation data
Robert S. Laramee, Helwig Hauser · 2005
Visualization of CFD simulation data on unstructured, threedimensional grids poses several challenges.The wide range of realworld data set sizes and the geometric versatility within individual, CFD simulation models present challenges to the engineers analyzing simulation results.Users also face perceptual problems such as occlusion, visual complexity, lack of directional cues, and lack of depth cues.We present a collection of geometric flow visualization techniques that address these challenges including oriented streamlines, streamlets, and a streamrunner tool.Two novel approaches are included: a real-time animated streamline technique and streamcomets.We place special emphasis on necessary measures required in order for geometric techniques to be applicable to real-world data sets.
