备注

针对西科大临潼校区宣传的需求,基于3D Max和OSG设计实现了一套临潼校区三维虚拟校园系统。首先,应用3D Max对整个临潼校区进行三维建模,提出了一种大规模建筑物场景的划分建模方法。然后,基于VS2005和OSG对临潼校区三维虚拟校园系统进行设计实现,提出了一种自主漫游碰撞检测方法,并实现了自动路径场景定位功能。应用结果表明,该系统达到了实时三维交互需求和预期显示效果。

To meet the demand of publicity for Lintong campus of XUST,a set of 3D virtual campus system of Lintong Campus was realized based on 3D Max and OSG.First,3D Max was used for 3D modeling of Lintong campus,and a division modeling method for large-scale building was presented.Second,the 3D virtual campus system was designed and implemented based on VS2005 and OSG,and a method for independent roaming collision detection was proposed.The automatic path roaming and interactive positioning features also were realized.The application results show that,the system could meet the expectations of real-time three-dimensional interactive display.
