基于图论和游离自由度的平面几何约束系统建立与求解的研究

On Establishment and Approach of Constraint Solving System Based on Graph Theory and Float DOF

为描述平面几何约束模型的求解系统,将游离自由度概念运用到图论中来表示系统的约束状态,并通过建立变量传递规则使数据的变化在图中合理流动,以实现清晰的表达参数系统的目的,达到参数变化快速驱动图形系统变化的效果。

To describe the solving system of plane geometry constraints, the concept of float DOF is applied in graph theory to represent the state of the constraints system. And through the establishment of the variable passing n^les, changes of the parameters can make rational flow in the graph so that the system can give a clarity expression and achieve the effect of fast driven of the graphics system changes.
