Dynamic Flow Volumes using Particle Level Sets
Background
Typically, flow volumes are represented and visualized by describing their boundary as the iso-surface of a level set function. The particle level set (PLS) method combines the advantages of both grid- and particle-based level set representations.This work demonstrates that the PLS method can be adapted to volumetric dye advection via streak volumes, and to the visualization by time surfaces and path volumes. This is achieved with a modified and extended PLS, including a model for dye injection. A new algorithmic interpretation of PLS is introduced in order to exploit the efficiency of modern graphics hardware, leading to an interactive visualization. Finally, the high quality and usefulness of PLS flow visualization is demonstrated by providing quantitative results on volume preservation and by discussing typical applications of 3D flow visualization.
