Additionally it is possible to link a business object with its graphical representation, e.g.room can be represented by a polygon, computer by an appropriate icon. 另外,也可以连接一个商业对象到它的图形表示,比如房间能表示为多边形等等。
The improvements for both the computation of visible polygon for given point in a simple polygon and the minimum link distance path between given vertex pair in a simple polygon have been made, which are used in the fast polygon decomposition algorithm based on point visibility. 对基于顶点可见性的凹多边形快速凸分解算法中所涉及的多边形中给定点的可见多边形的求解、给定顶点间的最短链路的求解等关键问题进行修改和完善。
