Simulation of Shrapnel Ejection Based on Vega And MFC

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.
