【摘要】 针对织物物理建模的计算效率和稳定性问题,提出基于约束的织物弹簧一质点模型。以简单几何实体球和圆柱为例,说明处理织物可变形体与环境对象碰撞的总体策略,结合实体碰撞对物理模拟流程进行总结性描述。同时,本文还提出了与已有建模方法进行了改进,即该模型并不包含对内力和质点速度项的显式计算,从而大大减少了计算量,在保证系统稳定性的前提下,较好的提高了计算效率。更多还原

【Abstract】 For computational efficiency and stability of cloth physical modeling,proposed a cloth mass-spring model based on constraint.Taking geometry sphere and cylinder as examples,the paper explains the whole strategy which is used to deal with cloth deformable bodies colliding with environment object.The procedure of physically based simulation is described.At the same time,this article also raised the improved method,that is,the model does not apply to the internal forces of particle and speed of the explicit terms,and greatly reducing the amount of calculation,to ensure the stability of the system,it is Good to improve the efficiency of the calculation.更多还原
