%X 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.
