森林资源信息三维虚拟仿真系统研究

Research on Forest Resources Information 3D Virtual Simulation System

利用二维GIS和三维场景虚拟仿真技术的各自特点及优势,将二维GIS和三维场景仿真技术结合应用于森林资源信息可视化中,采用面向对象的编程方法,使用VC、OpenGL开发工具,以全要素地形图、林相图数据为基础,构造各类地物要素模型,建立森林资源信息三维虚拟仿真系统。通过消息通信的方式实现二维GIS与三维虚拟仿真之间的交互,实现对森林资源历史、现在、未来的变化过程虚拟仿真,有助于拓宽森林资源管理人员的视角,对森林资源动态变化过程有更直观、全面的认识。

According to the characteristics and advantage of 2D GIS and 3D virtual simulation technology, 2D GIS and 3D virtual simulation technology were applied to forest resources information virtual simulation, Using VC, OpenGL developmental tools with the object-oriented programming methods, features various model base on terrain and the forest resource information 3D virtual simulation system were built. Through messaging, the 2D GIS and 3D virtual simulation interoperability were realized, the virtual simulation of forest resource history, present and future changing process was realized, which broadened the forest resource directors＇ angle of view, we had more audio-visual and overall understands of the forest resource dynamic changing courses.
