Abstract

The invention relates to an edge sampling and edge binding method based on an optimal transmission theory, and belongs to the field of graphics and visualization. The method comprises the following steps: S1, inputting a node connection graph, and clustering edges based on directions and distances by utilizing a hierarchical clustering algorithm and using different distance functions; S2, samplinga common edge from each type of edge set as a skeleton by using an optimal transmission theory; S3, respectively selecting end points and gravity center points of the edges as control points to drawtwo cubic Bezier curves, and connecting end points of the curves; S4, setting low transparency for the Bezier curve part, setting high transparency for the end point connecting line part, directly drawing short edges and setting extremely low transparency; and S5, measuring the excessive drawing number of each pixel, and further emphasizing binding by using an OpenGL rendering technology. The method has a good binding effect, the clustering number can be changed to control the binding tightness, and a user can recognize the main skeleton structure of the whole data set at a higher layer.

Description

technical field [0001] The invention belongs to the field of graphics and visualization, and relates to a side-sampling and side-binding method based on optimal transmission theory. Background technique [0002] Data visualization mainly uses graphical means to explain data, so that users can conduct in-depth observation and analysis of data. There are many visualization methods today, and different data types can use different visualization methods. Among the many visualized objects, the node connection graph is a basic and important structure. It is composed of vertices and edges and is suitable for representing entities and entities. The relationship between entities is represented by vertices, and the relationship between entities is represented by edges. The node connection graph is widely used, and many problems can be solved by establishing a node connection graph model, such as hierarchical structure and network structure. However, as the scale of data increases da...
