摘　　要：在分析X3D(Extensible3D)与VRML异同点的基础上,对X3D的系统运行内部机制进行了讨论,并使用SAI(SceneAccessInterface)的方法对虚拟场景进行交互。对通过外部原型操作物体定性运动进行了分析,并说明了具体实现的方法。以X3D-EDIT作为原型系统的开发工具,给出了虚拟环境中实现人机交互的应用实例。The internal running mechanism of X3D was discussed after analyzing the similarities and differences of X3D (Extensible 3D) and VRML. The virtual scene was manipulated by the means of SAI (Scene Access Interface). The qualitative motion was analyzed by External Prototype and the realization method was illustrate in detail. The application instance of man-machine interaction in the virtual environment was illustrated with using X3D-EDIT as the development tool of prototype system.
