交互式三维包装纸盒CAD数据结构研究

Research on Data Structure Used in Interactive 3D Packaging Box CAD

根据三维包装纸盒结构特点和交互操作的要求,提出了纸盒结构树的数据结构,并给出了纸盒结构树的定义,讨论了纸盒结构树的数据结构及盒型面创建、修改的算法。实践证明,该数据结构能够简单直观地描述盒型面的拓扑关系,并且可以较为便利地实现交互式设计。

According to the structural features of 3D packaging box and the requirements to interactive operation,the data structure of box structure tree was put forward,the definition of box structure tree was given,and the data structure of box structure tree and algorithm for creation and modification of plane were discussed.The practice shows that the data structure can easily describe the topology of planes and handily achieve interactive design.
