虚拟战场环境中火炮外弹道可视化研究
|
摘要
在某合成战术对抗仿真训练系统中,为提高训练的沉浸感和打击仿真结果的可信度,需要对火炮弹丸的外弹道进行可视化建模与仿真。采用空气动力学简化方程对弹丸飞行轨迹进行数学建模,并用显示欧拉法求解弹丸在虚拟战场环境中的位置;然后对弹丸从发射、飞行到弹目交汇爆炸的全过程产生的视效、声效进行了可视化的设计;基于UNITY 3D仿真引擎对火炮弹丸的外弹道进行了渲染实现,并将算法模型封装为动态库,便于将来的复用。经部队试用验证取得了较好的训练效果。
In order to improve immersion of training and reliability of damage simulation result,Modeling and simulation of external trajectory visualization for artillery shells are required in a combined arms tactical countermeasure simulation training system. Firstly, aerodynamic simplified equation is used to model the artillery shell‘s trajectory in this paper,and the Euler method was used to calculate the position of the projectile at every simulation period in the virtual battlefield environment;Secondly,the visual effects and sound effects associated with the artillery shell projectile are designed in the whole process from shell lauching,flight to collision of shell with target. Finally,external trajectory visualization for artillery shells are rendered using unity 3D platform. and the argorithm is encapsulated in the form of a dynamic library for later reuse. It gets a better training effects after PLA's trial.
