基于Vega Prime的直升机反潜机动三维视景仿真

针对直升机反潜的实际过程,以使用吊放声纳搜潜为例,建立了直升机反潜搜索时的机动航路解算模型;在解决三维实体动态加载、直升机旋翼表现、坐标变换等关键技术的基础上,给出了基于Vega Prime的视景仿真软件设计思路。最后以VC为开发平台,编程实现了直升机反潜过程的三维视景显示,仿真效果理想,对开发类似的作战过程视景仿真系统具有一定参考价值。

3D Scene Simulation of Helicopter Antisubmarine Search Based on Vega Prime

To simulate the process of helicopter antisubmarine search by dipping sonar,model is built to resolve parameters of helicopter’s flight track between adjacent hovering spots.Still,Key techniques of developing simulation program of 3D scene are analyzed,such as loading 3D object dynamically,displaying rotary wings,coordinate conversion.Then framework of 3D scene program is presented.Finally,combining VC and Vega Prime software,3D scene program which simulates the process of helicopter antisubmarine search,is developed successfully and the effect is perfect,which is helpful and could provide some reference for developing similar 3D scene program.
