MAXScript在构建部件级实景三维中的应用研究

Research on Application of MAXScript in Component-level 3D Realistic Geospatial Scene

针对当前以道路全息地图为代表的部件级实景三维产品如何实现快速构建,数据如何具有三维化、实体化、语义化特征等问题,将MAXScript脚本语言运用到部件级实景三维数据建设中,实现海量部件级三维模型的自动带参建模,以及地理实体对象不同形式数据的自动关联,保证了数据产品具有地理实体“一码多态”特征。方法经实践证实,可提高成都市道路部件级实景三维产品的建设效率和产品应用价值。

Aiming at the current problems of production efficiency,modeling processing,objectified processing,and semantic processing for road all-feature map which represent component-level 3DRS,this paper applies MAXScript to component-level 3DRS,to model massive city’s components quickly and realizes linkage in different forms of data for geo-entity.This method ensures that the product has characteristic of onecode polymorphism.Practice has proved that the application of this method can greatly improve the production efficiency for Chengdu road all-feature mapdata production and increase product value.
