【摘要】 探讨了在SGI公司的Onxy4可视化系统下基于OpenGL Performer^TM视景开发工具包构建虚拟现实仿真系统的流程;设计了用于运动仿真和交互的虚拟环境场景图（Scene Graph）和节点（Nodes）;研究了利用Performer对场景图中对象进行运动仿真的方法;探讨了场景中对象之间的交互规则、事件触发和反馈的方法;分别以虚拟人交互模型、某型号车系加工中心及某型号泥水平衡全断面盾构机为例构建了运动仿真与交互的运行实例。更多还原

【Abstract】 A simulation procedure founded on SGI Onxy4 visualization system and SGI OpenGL Performer^TM visualization development toolkit was discussed;a scene graph in accordance with its node configuration motion and man-machine interaction simulation were designed;based on OpenGL Performer,a transforming algorithm for scene graph object moving simulation was studied;the interaction rules between scene objects,the event triggering and feedback method of the simulation procedure was discussed and designed;and finally,separately took examples by a virtual man interaction module,a numerical lathing-milling machining center and a mud-water balanced tunnel boring machine,three operation instances for moving simulation and interaction were programmed and realized.更多还原
