The streamline is of great importance for the visualization of 3D vector field. In order to solve those problems of streamline occlusion and visual confusion caused by of excessive streamlines. Meanwhile the streamlines have to present the variation law and important features of vector field exactly. In this paper, a view-dependent and physical feature-preservation streamline simplification method for 3D vector field visualization is proposed. Firstly, streamline set of 3D vector field is generated by particle tracking. Secondly, view-dependent mapping of the streamline set is implemented. Finally, the streamline set is simplified effectively following an iterative feature-preservation computation and view-dependent computation. The experiment results show that the streamlines are visually enhanced meanwhile the physical features of vector field are effectively maintained.
