摘　　要：为了使仿真设计用户高效、快速地制作各类仿真应用系统,采用OSG(Open Scene Graph)技术,开发了一个实用方便的三维仿真设计平台(简称3DVR)。该平台在OSG基础上加以扩展,采用底层模块隐藏封装、模块整合等技术,构成一个使用更加方便的高级API函数库,在必要时可以使用底层函数进行二次开发。文中具体介绍了该平台各模块功能和特点、体系结构、相应关键技术以及应用实例,提供了一种可供进一步研发复杂仿真系统与应用的标准中间件的的方法,封装了各种通用的复杂仿真算法,使编程工作变得简洁明快。This paper studies the development of an useful and convenient design platform of 3D simulation （3DVR） using OSG（ Open Scene Graph） , as it can make the design clients construct different kinds of simulation application systems efficiently and quickly. The platform is extended based on OSG to form a more convenient advanced function base of API, by using the technologies such as bottom module hiding and packaging, modules integration and so on. The second development can be carried out using the bottom functions,if necessary. This paper introduces each module＇ s characteristics, architecture, key technologies and examples. The development of this platform gives a method for supporting the development of other complicated simulation systems and standard middleware. It packs various generic complicated simulation algorithms, and makes the programming work simple and quick.
