虚拟样机工程中的虚拟现实系统研究

为了提高虚拟现实(简写为VR)系统的性能，采用了虚拟场景显示与信息、交换分开的多层体系结构，利用可变长队列数据结构的并行扩展策略来提取虚拟样机产品的层次结构，并依据计算机视觉原理，利用二维视图和三维场景中点的对应关系，设计出了性能良好的路径编辑器，在提高VR系统性能方面提出了切实可行的措施，结果表明，在虚拟样机工程的实践中运用这些方法所设计的虚拟现实系统具有性能高的特点，证实了这些方法策略的有效性。

Virtual reality system for prototyping

In order to improve performance of virtual reality system, a multilayer systematic structure with se-purate virtual scene and information exchange is separate, a paralleling strategy of using changing queue is proposed. To extract the hiberarchy of a virtual prototyping product, a well performance path editor is designed using the corresponding of two dimension point and the dimension point. Measures are put forward to improve the virtual reality system. Results show that these measures are effective. A high performance virtual reality system is designed using these methods.
