摘　　要：为方便校内外学生、访问者更好地了解国家级实验教学中心,发挥实验教学中心的示范辐射作用,文中研究开发了一个基于Vega Prime 2.0的虚拟实验中心漫游系统,给使用者带来身临其境的临场感。运用LOD、DOF、纹理映射等关键技术,基于Vega-MultiGen开发了西南交通大学新校区及西南交通大学机械基础国家级实验教学示范中心的虚拟漫游系统,实现了自由漫游及目标对象的自动导航,将虚拟现实技术与地理信息系统相结合,实现了GIS属性查询等功能。为数字化实验示范中心、数字化实验室的建设探索了一条可行的技术路线。A virtual roaming system of experiment center based on Vega Prime 2.0 which will bring the feel of being real scene is researched and developed in this paper. This system is convenient for the students and other visitors to realize the experiment center of nation, and it＇s also benefit for experiment center showing its deraonstrating effect. The Vega- MultiGen based virtual roaming system of Southwest Jiaotong University＇s new campus and the national experimental demonstration center is developed in this paper, using key technologies such as LOD, DOF and texture mapping, etc. Virtual free roaming and automatic navigation are achieved. Furthermore, attributes querying of GIS is implemented by combining virtual reality technology with GIS. The paper provides a feasible technology method for the construction of the digital experiment centers and laboratories.
