摘要:

设计并实现一种海量三维城市景观的互联网络发布引擎.提出一种地形与地物相结合的多源数据集成模型,使地形块成为数据调度的最小单位,统一了地形与建筑物的网络发布;设计基于固定地形块数量的客户端数据调度算法和服务器端缓冲区设置算法,解决客户端和服务器端内存受限的问题;结合多分辨思想,采用ActiveX、OpenGL和多线程技术实现浏览器/服务器模式三维城市景观互联网络发布引擎.该技术对数字城市推广应用有重要价值.

Abstract:

An internet release engine for mass virtual scene of 3D urban landscape was designed and implemented.In the engine,multi-resolution DOM,DEM and building model data were integrated as a type of block-based multi-source data model(BMSDM),and a BMSDM block was used as a minimum data cell for internet releasing.An efficient data exchange algorithm between browser and server was also introduced,The algorifhm solved the problom caused by the limitation of data buffer size and bandwidth.Testing result show that our engine can efficiently transfer mass 3D GIS data on internet,with prompt responses to the internet users.This project is significant for applications of digital city technology.
