Abstract

The invention discloses an OpenSceneGraph-based real-time battlefield simulation system and method. The system comprises a model building module used for generating situation elements in a battlefield environment and an environment simulation module used for simulating the battlefield environment, wherein the environment simulation module comprises a terrain simulating unit used for terrain simulation according to a terrain database generated according to an elevation file, and a weather simulating unit used for obtaining the light color and intensity at a certain period of time by calculating the potions of the sun at different periods of time and rendering the light color and intensity onto the sky according to the sky environment, under different weather conditions, to be simulated. According to the OpenSceneGraph-based real-time battlefield simulation system and method, terrain simulation effect and weather simulation effect are real.

Description

technical field [0001] The invention relates to the field of real-time battlefield simulation, in particular to a real-time battlefield simulation system and method based on OpenSceneGraph. Background technique [0002] The visualization of the battlefield situation is to dynamically display the situation subjects existing in the battlefield (including personnel, weapons and equipment, a certain military indicator or events in the battlefield) on the graphics terminal. In the user window, specific military symbols are used to indicate the subject of the situation, such as attack direction, assembly area, maneuvering route, etc. [0003] However, the existing battlefield situation visualization technology does not have a clear division of functions and cannot achieve functional modularization, resulting in repeated development of the same functional modules in different projects, resulting in long development time and high cost investment. [0004] Secondly, the simulation o...
