摘要
分析了可用于公路三维建模的 3种方法 :线框模型、表面模型和实体模型的原理和特点 ,并结合公路三维建模数据量大 ,形体不规则的特点 ,提出用表面模型来完成公路三维建模 ;同时 ,也提出了道路模型与地面模型叠加消隐的新方法 ,以消除路基边坡范围内的地面 ,使道路能完整地体现出来。
The principle and characteristic of three methods called frame model,external model and entity model to build three dimensional model of highway is analyzed.Considering the numerous data in building three dimensional model of highway and the irregular shape,the method to build the three dimensional model of highway with external model is put forward. The new method of hiding the road model with the ground model to remove the ground inside the range of roadbed is presented to make the highway appear completely.
