摘要

Streamline querying is one of the important research directions in flow visualization, which can be widely used in streamline clustering, feature detection, etc. And the querying accuracy is the key to this field. So this paper proposes a new querying method with higher accuracy for streamlines in 3D flow visualization than the state-of-the-art methods. We define the finite substructures which are constructed by four neighboring equidistant sampling points from the streamlines. Firstly, we propose a new uniform segmentation method to transform the streamline to substructure sets. Then, by regarding the substructure as the character' and the substructure sets as string,' we evaluate the similarity of each streamline with the edit distance of strings. Finally, we specially design an algorithm for streamline querying by control functions so as to demonstrate the effectiveness of our new method.
