摘　　要：根据飞行视景仿真和某飞行器模型的特点,利用Multigen Creator对导入的三维机械模型进行重新建模和优化;从如何修改模型数据库结构和减少模型复杂度和尺寸等方面入手,对飞行器的视景三维仿真模型的建立和优化方法进行了研究,解决了模型的逼真度和视景仿真的实时渲染速度之间的矛盾,最后对优化前后的模型通过在飞行视景仿真实验中的调用得到对比参数,表明了这种优化策略对提高复杂模型驱动速度、仿真效果和节省计算机资源开销有着很大必要性。According to the features of the flight visual simulation and the aerocraft, the imported mechanical model is reconstructed and optimized using Multigen Creator. In this paper , the method of 3D modeling and optimization techniques are explored from the aspects such as adjusting the model database , reducing the model complexity and size , and so on , and the contradiction of fidelity and the speed of visu al simulation is solved . Finally, comparing the running performance parameters before and after the model optimization, it proves that the strategy is very necessary to increase the speed of driving complex model , enhance the performance effect of simulation and save the resource cost of computer.
