项目摘要
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.
对于非定常流数据的可视化,粒子轨迹或路径线的跟踪和表示是一种标准方法。处理路径线的研究仍然少于考虑流线的研究,导致基于流线的技术比路径线技术发展得更好。本项目提供了一种通用的方法,将非定常矢量场V的路径线转换为另一个(定常或非定常)矢量场W的流线。在此基础上,我们将开发一种基于纹理的流动可视化方法,允许研究路径线行为在一个单一的图像。此外,我们打算在大型三维非定常流数据集的交互式粒子跟踪作出贡献。最后,将设计并进行用户研究,以评估路径线2D不稳定矢量场的感知。
