摘要
针对织物动画模拟中的实时性问题,采用质点-弹簧模型来描述整个织物运动系统,并提出了MDFP和MBFGS两种新的基于拟牛顿的实时数值解法用于织物动画的实时模拟.为保证收敛速度,给出一个选择策略,根据实时状态对两种算法进行自动选择.实验表明,本文算法在收敛速度和整体性能上均优于已有算法.
This paper presented two real-time numerical solutions, which are based on the quasi-Newton method, of cloth animation in which a mass-spring model is applied. To get more efficiency, a way on how to do with the tolerance was given to deal with the different situation by integrating the two algorithms. The experiment shows that the real-time numerical solutions are much more efficient on both the speed of convergence and the general performance.
