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 streamlines of another (steady or unsteady) vector field w. With this, existing stream line techniques can be used to 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 to evaluate the perception of path lines 2D unsteady vector fields.
