摘要
从城市元胞自动机模型的角度研究三维虚拟城市的自动化生成方法。通过建立城市元胞自动机模型,模拟城市土地单元的演化过程,根据演化结果确定各土地单元的空间位置和相应的建筑物类型。研究利用Creator进行三维场景建模,利用OpenGVS场景管理技术随机生成建筑物,并将其布设在三维场景的相应位置上,生成三维虚拟城市,并就三维虚拟城市自动化生成系统的功能结构设计和数据结构、空间坐标转换等技术问题进行了探讨。
This paper makes research on the methods of automatic-generation of 3 D virtual city from the view of urban cellular automata model. The evolution process of the urban land units can be simulated by constructing urban cellular automata model, and then the results of evolution will determine the space location and corresponding building types of land units. Our research makes use of MultiGen Creator to build 3D scenes, and scene management technology of OpenGVS to generate buildings at random, then these buildings will be set on corresponding locations of 3D scene so as to generate 3D virtual cities. We develop 3D virtual city automatic-generation system and also discuss the application potential and value of it in the field of municipal administration, urban planning, urban research, etc.
