Embodiment Construction

[0150] Please see attached figure 1 , 2 , 3, 4, and 5, a hardware environment for rapid display and browsing of massive models of a 3D geographic information system, including: a client and a server, and two servers for storing and publishing 3D model data, and one for storing and publishing vectors The data server of layer shp 6 and the client used for 3D scene browsing 8 constitute a browser / server B / S system architecture. Based on the Skyline TerraSuite series software, the seamless link between the terminal and the data publishing server is completed through the Web server. In the browser environment, users are provided with three-dimensional data browsing and query services, and the above at least three servers and the client are all network transmissions.

[0151] Further, Windows Server 2008 operating system is set on three servers of the hardware environment for quick display and browsing of massive models of a three-dimensional geographic information system, and the...

Abstract

The invention relates to the field of three-dimensional geographic information systems, in particular to a method for rapidly displaying and browsing massive models of a three-dimensional geographic information system in a three-dimensional scene at high efficiency by utilizing SkylineTerraSuite series software which is mainly applied in more than 75,000 three-dimensional models in Shanghai. In the method, a browser/server B/S system architecture consists of at least three servers and a three-dimensional scene browsing client, and massive three-dimensional models are rapidly displayed and browsed in the three-dimensional scene by using technologies in three-dimensional data optimization, model management, model data network transmission and the like. By the method, related technical problems of model format optimization methods, massive model management methods, three-dimensional model network transmission methods and the like are mainly solved. The invention has the advantages that: the scene display speed is increased, the efficiency of model release, loading, query, addition, modification and the like is improved, the displaying and browsing speed of the models is increased, and the reading speed of data and the displaying speed of the models are increased.

Description

technical field [0001] The present invention relates to the field of a three-dimensional geographic information system, especially a technology that is mainly applied to more than 75,000 three-dimensional models in Shanghai, using Skyline TerraSuite series software, and adopting three-dimensional data optimization, model management, and model data network transmission. A fast display and browsing method for displaying massive 3D models in a 3D scene. Background technique [0002] Three-dimensional geographic information system GIS, based on spatial information, comprehensively uses remote sensing, virtual reality, global positioning system, computer network and other technologies to truly reflect the real appearance of a city in the computer, and its content mainly includes the topography of the city , buildings, roads, underground pipelines, and a large number of human and social attributes related to it. At present, in many fields related to urban construction, such as ur...
