摘要
在对几何约束进行求解时,一般先要进行适当分解,然后再根据分解得到的求解次序进行依次求解。当同时进行求解的约束数量较多时,必须采用数值解法。如果这样的循环约束中变量的数量较多,则采用全部变量迭代的方法会导致计算不稳定,且计算时间较长。本文提出了部分变量进行迭代的方法,大大降低了迭代变量的个数,增加了计算的稳定性,缩短了计算时间。
When solving a geometric constraint, we usually decompose it with proper methods. Then, it can be computed according to the sequences of decomposition. If there are many constraints to be solved at the same time, numerical methods must be applied. If all the variables in the concurrent constraint problem are iterated, the calculation process will become unstable and slow. This article presents a method with only partial variables iterated during the calculation process, which greatly reduces the number of variables to be iterated. So, the calculation process will be stable, and the calculation time will be shortened.
