摘要

由于特征模型对约束的强烈依赖和当前约束求解器速度的缓慢

对特征模型的直接操作并没有得到广泛应用.本文提出了一种新方法

把原始约束模型编辑成操作约束模型

基于操作约束模型在修改特征参数时能够最大限度地减少需要求解约束的数目

在此基础上对约束的求解采用自由度分析的方法

能够对特征模型直接操作中的约束进行最优化求解

从而使操作结果能够得到实时反馈

增强了操作的直观性.

Abstract

Due to the strong reliance of such systems on constraints and lack of speed of current constraint solvers

support for direct manipulation of features is not commonly available.This paper presents a new technique that optimally reduces the number of constraints to be solved when modifying a particular constraint variable

base on this solve constraints with degrees of freedom analysis

optimally solves constraints

so can obtain the real-time feedback on the consequences of the operation and enhance the intuiti...
