流动的分析和可视化是可视化的核心问题。近年来，基于拓扑的方法得到了越来越多的关注。本文介绍了一种检测三维流动中闭合流线的方法。它是基于一个特殊的处理情况下，流线重新进入一个细胞，以防止无限循环在流线计算。该算法检查可能的出口循环的交叉面，并检测结构稳定的封闭流线。传统的拓扑结构和特征检测算法无法检测到这些全局特征。
The analysis and visualization of flows is a central problem in visualization. Topology based methods have gained increasing interest in recent years. This article describes a method for the detection of closed streamlines in 3D flows. It is based on a special treatment of cases where a streamline reenters a cell to prevent infinite cycling during streamline calculation. The algorithm checks for possible exits of a loop of crossed faces and detects structurally stable closed streamlines. These global features are not detected by conventional topology and feature detection algorithms.
