织物物理模拟与三维服装实时仿真技术

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质点弹簧模型。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。实验结果表明,该建模方法相对于织物的几何复杂度有接近线性的计算效率,因此很适合于实时仿真环境。将上述研究成果集成应用到三维服装仿真环境中,给出了验证实例。

Cloth physical modeling and 3-D garment real-time simulation

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.The experimental results reveal that the computed data according to the model is very close to the actual values in spite of the complexity of the cloth geometry and it is suitable for real-time simulation.The above research results are applied to 3-D garment simulation environment,and examples are presented.
