摘　　要：柔性物体形状的变化通常很复杂,如何实现柔性物体形状的实时更新是一个难点,以随风飘扬的旗子为例,给出了一种联合使用粒子系统和弹簧结构实时构造柔性物体的方法,为了提高场景渲染速度,又提出了一种快速计算顶点法线的简化算法,还介绍了柔性物体实时可视化仿真所涉及到的关键技术。The form of flexible object is changing with no definite rule and the changing is very complex, so it is very difficult to implement the update of the flexible object＇s form. To make the model real time in the program, this article gives a method to simulation flexibility in real time by using the particle system and springs structure. Furthermore, to spthe vertex normal of flexible object need update real time too, this article uses a rapid method of calculating the vertex normal to improve the performance of visualization simulation.
