摘要
在分析图形实体几何约束的基础上 ,总结了基于各种关系构造图形实体集合的基本图素类型 ,提出了一种基于关系的参数化模型 ,建立了用基本图素类型构造图形之间关系相连的满约束的图形实体集合的数据结构 ,并在 PC机上采用面向对象编程技术用 Visual C++完成具体的存储和运算 ,实现了全参数化图形的建模、编辑和拓扑结构的修改及尺寸驱动 .
The elementary graphic element types for constructing graphic entity sets based on various kinds of relations are summarized by the analysis of geometric constraints of graphic entities. A parameterization model based on the relation is presented. The data structure of fully constrained graphic entity set by relational connection is built. The graphic entity set is constructed with the elementary graphic element types. The concrete storage and operation are completed with writing a program in Visual C++ language using object oriented programming technology on PC. The modeling, editing, modifying of topology structure and dimension driving of fully parametric graphics are realized.
