Research on Tracking Topological Changes in Family of Objects Model
跟踪对象族模型拓扑结构变化研究

A novel algorithm of tracking topological changes of family of object models was imposed,relations between parameters and topology of models were established, critical values of parameters were computed, dependent entities of models were determined, stable intervals and parametric ranges were computed, and at last topological changes of family of object models were tracked accurately in this system. The algorithm was used in our HUST-CA)D system,and intelligent of system was improved, parametric ranges was determined for designers.
