为了检验光测设备跟踪性能,提出了一种基于MFC和Vega环境开发虚拟现实仿真系统的方法,详细阐述了开发过程。利用Multigen Creator建立子母弹仿真模型,根据子母弹抛撒的特定模型自定义粒子系统模拟子弹抛撒的全过程,在预定的抛撒点触发抛撒事件,实时更新子弹和母弹的飞行姿态和飞行速度。用MultiGen Vega来驱动视景仿真模型,并在仿真中添加了特殊效果,增强仿真环境的感染力和真实性。该仿真系统能够方便地对参数进行设置修改,直观地显示仿真结果,有利于对光测设备跟踪性能进行评价。

To test the tracking performance of optical measurement device,this paper discusses a method which is based on Visual C＋＋ and Multigen Vega environment to develop a virtual reality simulation system,and elaborates development process.The simulation models of the cargo projectile is established with MultiGen Creator.According to the particular model of Shrapnel ejection,a particle system to simulate the process of Shrapnel ejecting is defined.The flight attitude and flight speed of the bullets and mother bombs are updated in real-time when the shrapnel triggers the ejection event in the scheduled throw-point.Simulation models are driven by MultiGen Vega.Special effects are added to the simulation to enhances the infectious and authenticity of the simulation environment.The parameters of simulation system can be easily modified and the simulation results are shown directly,these make the tracking effects evaluation of optical measurement device easily.
