Visualization of time-dependent 2D vector fields based on topological method
基于拓扑法的与时间相关二维矢量场的可视化

In the visualization of time-dependent 2D vector fields, closed streamlines detection was dependent on grid and could not locate closed streamline accurately. An improved method was proposed. It tracked critical point with feature flow field and integrated stream surfaces with saddle connector. The results demonstrate that the scheme is valid in offering a general framework for the visualization of parameter-dependent 2D vector fields.
