基于Virtools的三维城市仿真系统建设——以重庆北部新区为例

Construction of Three-dimensional Urban Simulation System Based on Virtools——Takes Chongqing new north zone for Example

结合北部新区三维城市仿真系统建设,从三维模型构建、模型库组织、系统功能等方面进行了阐述,同时针对系统海量数据的实际情况,探讨了"动态加载"关键技术的使用。

According to the construction of three-dimensional urban simulation system for Chongqing new north zone,this paper describes many respects,such as three-dimensional modeling,model-base organization,system functions,and discusses the key technologies of dynamic loading in accordance with mass geographic data.
