Problems solved by technology
At home and abroad, there are many researches on the visual simulation system based on the HLA standard, but most of these systems are developed directly based on the interface functions provided by HLA, requiring developers to master various service interface functions in the HLA specification, and the development time is relatively long
In addition, due to the large number of object classes and changes in the number of entities contained in the distributed interactive simulation system, the visual simulation system implemented in this way also has the problem of poor versatility. Often an independent application scene needs to customize a set of visual Simulation System

A configurable distributed 3D visual simulation system, including a scene configuration module, a configuration analysis module, a data interface module, a message processing module, an entity management module, a scene driver module and a user control module; the simulation is realized through the configuration mode of a graphical interface The process performance function configures special effects for various performance events of simulation entities, provides performance configuration file templates for basic simulation entity types, and provides visual performance configuration tools. Supports dynamic loading of corresponding shapes and effects during the simulation performance process according to the message type of the performance event and the performance configuration information. Using the inheritance mechanism of the HLA object model, the data of the 3D entity model of the visual simulation and the corresponding entity model of the distributed simulation system are automatically associated, eliminating the cumbersome data ordering process when the general visual simulation system is added to the simulation platform as a federation.
