摘要
文章聚焦于城市三维模型Internet发布时必然会遇到的网络响应速度、响应时间问题,在分析现有方法不足的基础上,从三维建模效率、策略和三维模型数据量入手,结合三维城市模型自身特点,提出一套解决方案,使广域网环境下城市三维可视化走向实用,达到工程化应用的目的。实验系统证明方法有效可行。
There are still some difficult problems on realization of 3D visualization on web. Compare to computer and LAN environment, network response time will largely influence the results of 3D visualization in Web environment. According to this problem, this paper focuses on 3D modeling＇ efficiency and 3D Scene data amount, analysis the shortages of existing methods, puts forward an effective solution to shorten network response time, in order to realize city 3D visualization on Internet. This paper introduces the key technologies and methods, such as the method on real-time city＇s 3D scene construction on Internet base on model library, and the method on 3D modeling based on module and reference. The test system proved the solution is useful and affective.
