基于OSG的体育场馆三维展示系统

The 3D Exhibition System of Gymnasiums and Stadiums Based on Open Scene Garph

基于OSG技术设计实现了体育场馆的三维展示系统,对体育场馆和比赛场景建模。在该系统中,管理员可以对体育场馆的不同比赛场景进行编辑,对体育器械的摆放区域进行设定,用户可以多种方式和路径漫游体育场馆,如自动和手动漫游场馆,可以自己编辑漫游路线,也可以在权限范围内编辑场景,模拟训练。在本系统中,提出采用知识描述的方法来确定场馆内体育器械允许摆放的位置,并采用四元数来描述器械摆放的角度。该文对OSG技术在本系统中的关键应用,如OSG数学基础、OSG内存管理、OSG的场景显示等问题进行阐述。

The 3D simulation system of gymnasiums and stadiums based on virtual reality is implemented based OSG.In this system,the ad.ministrators can edit the different scenes of the sports and set the display area of sports equipment;meanwhile the users can ramble gymnasi.ums and stadiums by all kinds of ways and paths,such as automatic and manual rambling.It can edit rambling routes and also can be within the purview of editing scenes,simulation training.It proposed using the method of knowledge description to set the allowance display area of the sports venues,and using the quaternion to describe the perspective of equipment display.This paper introduced the key application of OSG in this system,such as mathematics base of OSG,memory manager of OSG,scene displaying of OSG etc,it proposes the method to describe the knowledge of the location of the sports equipments.
