| 摘 要： | 在交互式三维包装纸盒CAD中,需要以对象的拾取为基础来对每个纸盒基本构成对象进行操作。给出满足三维包装纸盒交互设计的数据结构和对于面、面内线段、面内点3个层次对象的拾取方法,并开发了交互式三维包装纸盒CAD系统。实践证明,此方法可以很好地实现层次对象的拾取,满足系统对各种交互操作的需要。

| Abstract: | The operation on basic constitutive object based on object pickup was required in interactive 3D box CAD. Data structure used for interactive design of 3D box CAD and pickup methods of three-level objects in plane,line in a plane,and point in a plane were introduced. The interactive 3D paper box CAD system was developed. The practice showed that the methods can realize pickup of different level object,and meet the requirement of interactive operation. |
