虚拟衣物仿真为网络购物提供了很大便利。首先通过建立衣物的物理模型，将柔性衣物离散为分布均匀的质点，进而进行动力学受力分析。为获得高效且稳定的算法，采用隐式积分方法对微分方程进行数值求解。碰撞检测问题是布料仿真研究中的重要内容。针对具体碰撞对象设计了高效的碰撞检测方法，采用建立AABB层次包围盒树作为碰撞响应算法。最后进行布料产生碰撞后趋于稳定及滑落的动态仿真演示和穿衣过程仿真演示。该方法在达到较高计算效率的基础上，确保了仿真系统的稳定性。

Virtual clothing simulation greatly facilitates online shopping.First, we disperse the flexible clothing into evenly distributed mass points by building the physical model of clothing, and then carry out dynamics stress analysis.To achieve efficient and stable algorithm, implicit integration method ( IIM) is employed for the numerical solution of the differential equation.In research of cloth simulation, collision detection is important.We design an effective collision detection method targeted at the specific colliding objects, and use AABB hierarchical bounding box tree as the collision corresponding algorithm.Finally, we present the dynamic simulation displays for the situation of the cloths coming to still or slipping to ground after being collided and for the dressing process.This method ensures the stability of the simulation systemon the basis of achieving higher computation efficiency.
