三维信息系统的建设离不开逼真的实体模型,地下管线三维模型包含固态模型和动态模型。以昆明市地下管线三维系统中的模型建设为例,探讨地下管线三维模型建设中关于数据检查处理、存储设计、动态模型造型方法、模型数据创建工艺流程和取得的效果等方面的内容。
The construction of three-dimensional information system can not be separated from the realistic entity model. The underground pipeline three-dimensional model includes the solid model and the dynamic model. Taking the model construction in the three-dimensional system of underground pipeline in Kunming as an example, this paper discusses the content of data inspection and processing, storage design, dynamic model modeling, the process of model data creation and the effects achieved in the construction of 3D model of underground pipeline.
