Background technique
All there is partition data in many application fields, i.e., the plane domain for having clear boundary and shape is subdivided into more
A smaller region, the zonule after subdivision are known as segmenting the child partition of forefoot area.Each child partition is also each to have the bright of oneself by oneself
True boundary and shape.This subregion usually not only level-one, but there is multistage subdivision, constitute a partition tree.Such as political affairs
Area, country can be subdivided into multiple provinces, and each province is divided into multiple cities, and city is divided into multiple counties, and county is divided into multiple townshiies, constitute province,
City, county, township's level Four subregion.
The partition tree data of multiple levels are usually required graphically to express, form multistage subregion special topic
Figure.Display for the partition tree comprising two or more levels, at present mainly include the following types:
It is traversed along tree construction, only shows present node every time.This mode is convenient for expressing the shape, big of highlighted subregion itself
The information such as small, but the topological inclusion relation that is beyond expression between highlighted subregion and its ancestors' subregion, the highlighted subregion that is also beyond expression exist
Absolute position in its ancestors' subregion at different levels；
In the same plane simultaneously show partition tree multiple levels or whole tree.This mode can be expressed easily
The absolute position of topological inclusion relation and each subregion between different subregions out.But multiple partition levels are expressed in the same plane
It when other, needs through serial of methods such as line width, Fill Colors, visually explicitly distinguishes which grade some subregion belongs to
Not, which subregion belongs to same rank etc., and is illustrated by legend.This visual means need to compare legend to manage
Solution, poor intuition, and with the other increase of partition level for needing while showing, intuitive can further be deteriorated.
Therefore, multistage subregion topological relation, absolute position, shape and good can preferably be expressed by needing one kind
The ladder special topic drawing generating method of intuitive.
Summary of the invention
