基于可变积分步长的布料仿真

在布料仿真中,积分步长的大小直接影响仿真的效率和稳定性,因此采用较为常用的弹簧—质点系统建模,利用中点积分方法模拟布料的动态过程。在发生碰撞时,采用可变积分步长的方法提高系统的稳定性。实验表明,该方法在不影响仿真效率的情况下,提高了仿真的稳定性。

Cloth Simulation Based on Variable Integration Step

In cloth simulation,integration step direcdy influences the simulation system's efficient and stability. Therefore we uses the mass-spring model,which is used popularly,and middle-point Integration method to simulate the cloth.When the collision happens,we use the method of changeable integration step to improve the simulation system's stability.Experiments show that the method actually improves the system's stability without reducing the efficiency.
