For visualizing unsteady flow data, the tracing and representation of particle trajectories or path lines is a standard approach. Treating path lines is still less researched than considering stream lines, leading to the fact that stream line based techniques are much better developed than path line techniques.This project provides a generic approach to convert path lines of an unsteady vector field V to stream lines of another (steady or unsteady) vector field W. With this, existing stream line techniques can be used to visually analyze the path line behavior in V. Based on this, we will develop an approach to texture based Flow Visualization that allows to study the path line behavior in a single image. Also, we intend to contribute to interactive particle tracing in large 3D unsteady flow data sets. Finally, a user study will be designed and carried out to evaluate the perception of path lines 2D unsteady vector fields.

为了可视化不稳定的流数据，粒子轨迹或路径线的跟踪和表示是标准方法。与考虑流线相比，处理路径线的研究仍然不那么研究，这使得基于流线的技术比路径线技术要好得多。该项目提供了一种通用方法，可以将不稳定矢量字段V的路径线转换为另一个（稳定或不稳定的）矢量W的流线线的流线线，从而将基于此的流媒体技术用于该线路，以开发该线路，从而在vertinure中使用该线路，从而在vertine上进行了访问，从而将线路用于v。允许在单个图像中研究路径线行为。此外，我们打算为大型3D非稳态流数据集中的交互式粒子追踪做出贡献。最后，将设计和进行用户研究，以评估路径线2D不稳定矢量场的感知。
