摘要
讨论了一种基于弹簧质点模型的织物变形仿真技术,并提出了一种变形约束技术.在建立弹簧质点模型的基础上,通过受力分析得到织物变形的动力学方程,采用RungeKutta算法结合变形约束求解其方程,实现了织物变形仿真.用很少的运算时间取得了满意的仿真结果,证明了本弹簧质点模型的实时性.
The paper presents the simulation technology of cloth modeling based on mass spring model. A new method on deformation constraint to avoid super-elastic effect is proposed. A cloth object is approximated to a deformable surface composed of a network of masses and springs, the movement of which is evaluated using the numerical integration of the fundamental law of dynamics. The equation results are obtained using Runge-Kutta algorithm with strain restriction condition. The paper shows good simulation result with little run-time and the good practicability of mass spring model.
