3维城市模型建模方法分类与建模流程探讨

摘要

There are various ways of city three - dimensional modeling; each is different in the amount of data, modeling efficiency, fidelity, data management, and scope of application, topographical complexity, geometrical complexity, texture complexity. It is worthy of discussion how to choose the suitable method of 3D city modeling in order to standardize the workflow of modeling.%3维城市模型建模方法有很多种,每种方法在数据量、建模效率、逼真度、数据管理、适用范围、拓扑复杂度、几何复杂度、纹理复杂度等诸多方面都存在差异,如何选择一种适合实际情况的3维城市模型建模方法,规范建模流程,是一个值得讨论的问题.
