| description | Streamline generation is an important technique for vector field visualization. Streamline uniform placement algorithm can make streamline distribution evenly and express vector information better. An effective streamline placement method should effectively express the characteristics of vector field, make the streamline distribution uniform, and allow the streamline length to be as long as possible. In this paper, a dynamic seed placement algorithm based on critical points and grid points is proposed. The algorithm firstly finds and retains the key points to ensure the key information of vector field, and then introduces uniform grids to control the streamline density of vector fieldso as to guarantee that the streamlines are evenly distributed. The experimental results show that the proposed algorithm can display the characteristic information of vector field well, makes the streamline distribution uniform, and allows the length of streamline to be long. As a result, there are almost no short streamlines. |
