基于Vega粒子系统的自由大气分子运动虚拟仿真

在军事训练中,三维仿真的战场环境发挥了极为重要的作用。本文将对战场环境中的自由大气进行虚拟仿真。首先分析自由大气中运动分子的性质,详细介绍在模拟不规则自然现象中运用最多的粒子系统技术,最后在Vega中运用粒子系统对大气分子的运动进行模拟仿真。仿真结果能基本模拟出大气分子的运动特性,且可以通过接口编程访问粒子的属性,从而能在无人机等航迹规划的危险天气现象的规避中加以运用。

Virtual Simulation of Free Atmosphere Molecular Motion Based on Vega Particle System

In military training, the three-dimensional simulation of the battlefield environment plays a very important role. The article virtually simulates the free atmosphere in battlefield environment. First, the article analyzes the nature of motion molecular in the free atmosphere, and then describes the particle system in detail which is used mostly in the simulation of irregalar natural phenomena, and finally uses the particle system to simulate the movement of atmospheric molecular in Vega. The simulation results can basically simulate the motion characteristics of atmospheric molecules and the properties of particles can be accessed through the interface properties of programming, which can be used in flight path planning of UAV to avoid the dangerous weather phenomena.
