Embodiment Construction

[0029] In order to achieve the above purpose, the present invention needs to include four parts: user terminal, international communication network, Web server, WebGis simulated reality three-dimensional virtual ecological server system.

[0030] The specific creation steps are: including three stages of 3D virtual reality modeling, WebGis intelligent information query, and GTC-LOD large-scale scene real-time quick browsing.

[0031] It is characterized in that: the user uses the terminal to send a service request to a remote server, and then accepts the result from the server and expresses it; the international communication network is connected between the user terminal and the WebGis simulation reality three-dimensional virtual ecological server system Link, it sends the user's request to the WebGis simulated reality three-dimensional virtual ecological server system through the network, and then transmits the analysis result of the server to the user terminal; the described...

Abstract

The invention relates to a virtual ecological simulation system used in three dimensional online which is generated in virtual environment by using WebGis (World-wide-Web) and GTC-LOD (Level of Detail) technology. On the basis of using WebGis's powerful space data process and space analysis ability, a living three dimensional ecological environment mould is created by using virtual reality technology to attract browsers watching, and meanwhile the system can act as a monitor action such as ecological system dynamic investigation, ecological program and resource reasonable utilization etc. Another, after colligating GRC-LOD technology, large scale ecological system scene three dimensional real time online scan can be realized, which not only provides convenience to intercommunion and travel but also assists the government to carry out macroeconomic control and programming decision in order to create a new virtual reality system in which human and the nature can harmoniously develop.

Description

Technical field: [0001] The present invention relates to a three-dimensional online virtual reality simulation system and method, in particular to a real-time fast browsing algorithm for large-scale complex scenes combined with World Wide Web geographic information system (Web Geographic information system, WebGis) and GTC-LOD (Level Of Detail) The simulation design and implementation of the ecological environment system, the system and its method that can share and exchange information dynamically and intuitively. Background technique: [0002] At present, a variety of virtual reality roaming solutions have appeared on the market, some use two-dimensional maps embedded in GIS technology for information acquisition and query; there are also some websites that make urban buildings three-dimensional and modeled, and also have two-dimensional map information search functions . The trend of 3D online has become increasingly clear, but the 3D virtual reality on the market can on...
