摘要
虚拟漫游系统的开发是虚拟现实技术的一个重要应用。以华北电力大学保定二校区为虚拟仿真环境,使用3DS MAX建模工具对校园中的各种模型进行建模,使用多种基于几何建模的场景优化措施,并基于Google Earth卫星截图进行场景的精确布局设计。结合Virtools虚拟现实开发平台,设计了虚拟校园漫游系统的开发流程,并在微机平台上实现了一个场景复杂的校园实时漫游系统。该校园漫游系统不但为用户提供了友好的Web界面,而且设计并实现了基于导航图控制的人机交互机制,便于综合使用多种漫游方式快速漫游校园的场景。
Virtual walkthrough system is an important application of the virtual reality technology. Based on the virtual simulation environments of the second campus of north China of electric power university in Baoding, the 3DS MAX modeling tool is used to construct the scene of campus which is optimized by a variety of techniques based on geometric modeling, and the accurate layout design is implemented by the Google earth map. The process of the development of the virtual campus walkthrough system is designed and finally the system including complex scenes in PC is implemented. The walkthrough system not only provides friendly web interface for users but also designs and implements the way of human computer interaction based on navigation map to use a comprehensive means to walkthrough the scene of campus quickly.
