摘要
提出了一种时序处理技术,用以控制场景中物体的运动轨迹,顺序,时间的。它是轨道交通警用地理信息系统的关键技术之一。根据用户定义的关键节点和时间,创建时序类。在播放时序动作时,调用时序类的相关方法实时计算时序定义的运动路径上的各个点。建立一个控制类,控制协调所有时序的计算处理。由此可以控制物体在各自定义的路径上运动。
A scheduling process technology is designed and developed, to control the movement of models in 3D scene. Scheduling process is one of key technology in track traffic GIS for police. The scheduling object is created according the key points and time which user defined. Then it compute every way points by calling the method of scheduling object. At last, a controller class is design to manipulate all scheduling objects. As a result, the model is controlled to move in definated way.
