Keywords-streamline placement, seeding strategy, boundary extending of vector field, vector field topology, virtual control grid, vector field visualization I.  ...  Initial streamlines segment the field into topological areas.

Topology-Aware Evenly Spaced Streamline Placement

Keqin Wu, Zhanping Liu, Song Zhang, Robert J Moorhead
2010 IEEE Transactions on Visualization and Computer Graphics  
In each region, a seeding path is selected from a set of streamlines integrated in the orthogonal flow field.  ...  The uniform sample points on this path are then used as seeds to generate streamlines in the original flow field. Additional seeds are placed where a large gap between adjacent streamlines occurs.  ...  ACKNOWLEDGEMENTS This work was supported in part by the Northern Gulf Institute, a NOAA Cooperative Institute.  ...
