Abstract

The invention discloses a three-dimensional rendering engine system based on the geographical information and relates to the geographical information processing and application technology field. The system is characterized by comprising a rendering entity management module, a rendering driving module, a rendering operation abstractness module and a rendering operation module. The system realizes that geometric data formats and the OGC international standards are compatible, and mutual transformation with geometric objects defined according to the OGC international standards can be realized, moreover, rendering efficiency can be improved in the rendering process, so the geographic information data can realize multi-platform data sharing, and a reliable basic platform is provided for depth application of different industries, the application is displayed and spread in multiple projects such as realizing virtual real environment representation, and auxiliary sale and auxiliary office are further realized.

Description

technical field [0001] The present invention relates to the technical field of geographic information, in particular to management based on geographic information data, spatial data organization, retrieval and analysis, organization and management of three-dimensional entity objects, efficient scheduling of massive data and sharing of models and textures, and geographic information data A 3D rendering engine system based on geographical information for 3D simulation application. Background technique [0002] Geographic Information System (Geographic Information System or Geo-Information system, GIS) is sometimes called "geographic information system" or "resource and environmental information system". It is a specific and very important spatial information system. It is a technical system that collects, stores, manages, calculates, analyzes, displays and describes the relevant geographical distribution data in the entire or part of the earth's surface (including the atmosph...
