Example Embodiment

[0024] The present invention will be further described below in conjunction with the drawings. Such as figure 1 Shown is the structure diagram of the simulation system of the present invention, including a scene configuration module, a configuration analysis module, a data interface module, a message processing module, an entity management module, a special effect management module, a scene drive module, a user control module, and a distributed rendering module.

[0025] The scene configuration module in the present invention uses XML Path technology to find and parse the basic special effect elements in the ACF file for users to select and configure; use OpenFlight API to read the node configuration information of the three-dimensional modeling file. The user configures the simulation scenario configuration information according to the combat requirements, including terrain scenes, simulation entities, special effects and events. The configuration files are saved in XML format an...

Abstract

A configurable distributed three-dimensional scene simulating system comprises a scene configuring module, a configuration analyzing module, a data interface module, a message processing module, an entity managing module, a scene drive module and a user control module. The simulation process is rendered by configuring a graphical interface, special effect configuration is performed on various rendering events of simulation entities, rendering configuration file templates are provided aiming at basic simulation entity types, and visualized rendering configuration tools are provided. Corresponding styles and effects can be dynamically loaded according to message type and rendering configuration information of rendering events during simulation rendering. The heritage mechanism of HLA object models is utilized to achieve automatic data association of scene simulation three-dimensional entity models and the entity models corresponding to the distributed simulation system, and the complex data purchasing process of a common scene simulation system, as a federation, joining a simulation platform.
