摘要
研究织物变形特定性优化问题,针对织物形状动态改变提出了一种基于物理模型方法仿真织物变形,对织物采用质点-弹簧模型进行建模,解决织物变形在实际中的真实特用性,对质点-弹簧模型作了简化,即在模型中减少一部分剪切弹簧。在求解模型中,采用简单的显式欧拉积分法来求解织物的变形方程。同时对织物与环境之间进行了碰撞检测与处理。仿真结果表明,设计的模型稳定性和实时性好,为实际实现提供了参考。
Simulation of the motion of cloth is an important part in virtual animation.The computational costs are still high.Cloth-object computer deformation simulation is an important research topic in the Computer Graphics.This paper presents a physics-based simulation of fabric deformation model approach,using a simplified mass-spring model for the cloth-object.To cope with the requirements such as real-time and stability cloth deformation,this paper makes the mass-spring model simple.This dynamic equation of the cloth-object model is worked out by the Euler integration method.Experimental results show that the model is good in stability and real time,and easy to implement.
