城市级三维GIS管理系统需要管理海量的三维模型数据,要想实现高效、稳定的海量建筑模型渲染,需要研究一套行之有效的模型调度方式和数据存储方案。通过总结实际系统建设过程中遇到的各种问题,研究出了使用数据格网调度模型和打包存储模型数据的方法,大幅提高了三维GIS中海量模型的调度效率。 更多还原

【Abstract】 City-level 3D GIS management systems need to manage vast amounts of 3D model data,in order to achieve efficient and stable mass building model rendering,need to study an effective model for scheduling and data storage solutions.This article summarized the actual system through the process of building problems encountered,developed a scheduling model using the data grid and package method of data storage model,substantial increased in mass of 3D GIS in the efficiency of the scheduling model. 更多还原
