Embodiment Construction

[0047] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0048] The present invention is based on the embodiment of the mobile platform near-earth space scene simulation method

[0049] The near-Earth space scene simulation in this embodiment is aimed at the simulation of the 3D digital earth. The mobile platform client is used to change the position of the viewpoint, calculate the visible range according to the position of the viewpoint, and determine the nodes and details to be rendered under the current viewpoint position and attitude. According to the generated new scene rendering node structure, delete the invisible nodes from the memory of the mobile platform client, and generate a list of nodes that need to load data, and based on the data to be loaded The node list sends data requests and loads the required data to the mobile platform client; the mobile platform client compiles the loaded im...

Abstract

The invention relates to a terrestrial space scene simulation method and system based on a mobile platform and belongs to the technical field of three-dimensional space visualization. According to the method, a mobile platform client is utilized to change viewpoint positions, a visual range can be calculated out according to the viewpoint positions, a node needing to be rendered and a subdivision degree in a current viewpoint position posture are determined, and a new rendered node structure is established; a node list needing to load data is generated according to a new generated scene rendered node structure, a data request is sent according to the node list needing to load data, and the required data are loaded to the mobile platform client; the loaded imaged and the loaded DEM data are separately compiled into texture and vertex buffer objects on the mobile platform client, the texture and the vertex buffer objects are drawn and displayed through three-dimensional drawing software, and the simulation of the three-dimensional digital earth on the mobile platform client is achieved. The method achieves the space environment visualization on the mobile platform client and is satisfied in visualization effect and good in user experience.

Description

technical field [0001] The invention relates to a near-earth space scene simulation method and system based on a mobile platform, and belongs to the technical field of three-dimensional space visualization. Background technique [0002] The near-Earth space environment is an important place for human space science activities and has a significant impact on human production and life. With the advancement of space science and technology research, people are paying more and more attention to space environment information. Space environment visualization simulation technology, as a tool for spatial knowledge understanding, is of great significance to space science research and daily life applications. The space environment refers to a space around the earth, with the earth as the core, and related to the earth. Research on space environment simulation technology has attracted more and more attention. With the support of the National 863 Program, scholars such as Lan Chaozhen a...
