基于Unity3D的地铁三维虚拟漫游设计

摘要

随着虚拟现实技术的飞速发展, 如何利用计算机展示现实场景的三维漫游效果, 己成为当下研究的热点.以Unity3D为平台, 利用3DMax软件进行场景建模, 结合Unity3D自身强大的界面交互技术, 完成整个南昌地铁一号线虚拟漫游系统的开发. 最后通过地面站点全景的外链衔接, 实现了地铁站内三维模型场景与地铁站外全景的一体化漫游功能. 实践研究结果表明, 整个虚拟漫游系统能够给用户带来直观的地铁漫游体验.%With the rapid development of virtual reality technology, the way we use the computer to display 3D models of realistic scene has become a research hotspot. The system based on Unity3D platform is constructed by using 3DMax to build the scene, combining Unity3D's prominent interface interaction technology to form Virtual Roaming System of Nanchang No.1 Metro Line. Finally, through the external link about ground station panorama, the system has integrated function of roaming subway station both inside and outside. The result shows that virtual roaming system can bring users intuitive roaming experience.
