| 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.

| Abstract: | This paper presented two real-time numerical solutions,which are based on the quasi-Newton method,of cloth animation in which a massspring 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. |
