基于VR的虚拟火炮行为仿真

针对虚拟武器装备行为仿真过程中存在的运动仿真复杂、多部件协调操作仿真困难等问题,本文基于虚拟现实建模工具构建了某型传统火炮的三维模型-虚拟火炮,为行军行为仿真过程中运动轨迹选取、运动姿态控制、碰撞检测及响应等问题提供了合理的解决方法;在用炮和收炮行为仿真过程中,重点设计了时间驱动算法来解决多部件之间的协调操作仿真问题。通过对虚拟火炮的特定行为进行可视化仿真,验证了文中行为仿真研究方案的合理性及算法设计的正确性。

Behavior Simulation of Virtual-Howitzer Based on Virtual Reality

It is difficult to simulate the artillery squad tactics and the collaborative operation of multi-component in the virtual battlefield environment. According to these problems, Virtual-howitzer is created by use of the VR modeling tool, and its behavior simulation flow is designed. The solution of the Virtual-howitzer behavior trajectory, motion posture, collision detection is put forward. Based on the step adjustment method of freedom degree, the time-driven algorithm is designed, which is used to solve the multi-coordinated operation between the components of simulation. Based on the solution and algorithm, the behavior simulation of Virtual-howitzer is visualized, which is shown that research program is reasonable and time-driven algorithm design is correct.
