有向图几何约束搜索技术的研究

RESEARCH ON THE SEARCH FOR GEOMETRIC CONSTRAINT OF DIRECTIONAL GRAPH

本文提出一种有向图几何约束搜索方法,通过约束识别,使原先互不相联系各元素对象建立起拓扑约束关系,完成了对图形的自动识别和理解,文中重点介绍了有向图的几何约束搜索算法,并给出了它在离线参数化设计中的应用。

A promising approach to off-line-parametric design based on the search for geometric constraint of directional graph has been put forward. By the search of geometric constraint, it sets up the topology constraint relation on the different element object, and achieves the identify for directional graph. The paper describes the algorithm of geometric constraint in detail, in the same time, gives the application for off-line parametric design on dimension-driven.
