Abstract

In flow simulations the behavior and properties of particle trajectories often depend on the physical geometry containedin the simulated environment. Understanding the flow in and around the geometry itself is an important part of analyzing the data.Previous work has often utilized focus+context rendering techniques, with an emphasis on showing trajectories while simplifyingor illustratively rendering the physical areas. Our research instead emphasizes the local relationship between particle paths andgeometry by using a projected multi-field visualization technique. The correlation between a particle path and its surrounding areais calculated on-the-fly and displayed in a non-intrusive manner. In addition, we support visual exploration and comparative analysisthrough the use of linked information visualization, such as manipulatable curve plots and one-on-one similarity plots. Our techniqueis demonstrated on particle trajectories from a groundwater simulation and a computer room airflow simulation, where the flow ofparticles is highly influenced by the dense geometry.
