本文介绍了一个实时的连杆机构动态仿真系统。该系统的开发是为了模拟VR应用中的机械行为。开发了一个3D建模工具的扩展，它提供了对VR场景建模的可能性，包括所有刚体的几何形状和机械参数以及它们之间的关节属性。对于动态仿真，使用基于脉冲的方法。该方法的特点是通过脉冲的迭代计算来满足各种约束条件。这种迭代技术的优点是它是快速和准确的结果可以实现。动态仿真系统采用高效的碰撞检测方法。对于检测到的每个碰撞，确定对象之间的接触区域以提供准确的碰撞响应。
This paper describes a system for dynamic simulation of linked rigid bodies in real-time. The system was developed to simulate mechanical behaviour in VR applications. An extension for a 3D modelling tool was developed which provides the possibility to model a VR scene including the geometries and mechanical parameters of all rigid bodies and the properties of the joints between them easily. For the dynamic simulation an impulse-based method is used. The distinguishing feature of this method is that all kind of constraints are satisfied with the iterative computation of impulses. The advantage of this iterative technique is that it is fast and accurate results can be achieved. The dynamic simulation system uses efficient collision detection methods. For every collision that is detected a contact region between the objects is determined to provide an accurate collision response.
