| 摘 要： | 变量化二维草图器（２ＤＳｋｅｔｃｈｅｒ）是一个基于约束图的参数化变量化图形设计系统。该系统采用一面向对象的数据模型系统表示几何元素与约束；采用了基于图的约束求解机构，通过对约束图的构建、分解、规组，并用递归的方法求解方程组；最后由用户在交互方式下选择所需的无二义的解

| Abstract: | D Sketcher is one of the variational design system which based on constraint graph.This system uses a date model which orient to object to present the geometric element and constraint.And uses a constraint solving system based on graph,with the construction of the constraint graph and the reduction of the constraint graph and the construction of cluster,and through the recursion algorithm to solve the equation.At last,we can get the unique root through one Root Select System which iterative and based on ruler. |
