虚拟校园整体景观的实现与互动
摘 要：虚拟现实技术在数字校园中的应用就是要将校园进行3D建模、制作材质贴图、烘焙带有灯光信息的贴图并结合VR软件实现桌面虚拟现实系统。实现校园宏观建筑，景观，植被，道路及各种设施的数字化。主要反映的是学校建筑物、道路、环境、部门及各区域的外部特征，实现西南林学院宏观的总体景观。选择西南林学院进行外观动态建模，是实现西南林学院数字化校园的一个重要组成部分，能在计算机上动态地浏览西南林学院的宏观外景，反映学校建筑物、道路、环境、部门及各区域的外部 特征，动态实现西南林学院宏观的总体景观。这对于宣传和扩大西南林学院的影响，将会取到很好的视觉效果。是数字化校园外观数字化的一个重要组成部分。

SWFC Virtual Reality Schollyard Macrocosm Sight Realize
Abstract: The virtual reality technology is must carry on in the digital campus application the campus the 3D modelling, the manufacture material quality pastes the chart, cures has the light information to paste the chart and unifies the VR software realization tabletop virtual reality system. Realizes the campus macroscopic construction, the landscape, the vegetation, the path and each kind of facility digitization. The main reflection is the school building, the path, the environment, the department and various regions exterior characteristic, southwest the realization SWFC the macroscopic overall landscape. Southwest the choice SWFC carries on the outward appearance dynamic modelling, is southwest the realization SWFC a digitization campus important constituent southwest, can dynamic glance over SWFC the macroscopic outdoor scene on the computer, the main reflection is the school building, the path, the environment, the department and various regions exterior characteristic, southwest dynamic realization SWFC macroscopic overall landscape. This regarding southwest the propaganda and the expansion SWFC the influence, will be able to take to the very good visual effect. Is a digitized campus outward appearance digitization important constituent.
