基于Mantis的某型直升机视景系统设计与实现

Design and Implementation of Visual Simulation System for Helicopter Based on Mantis

对直升机视景仿真系统的构建进行了分析,针对其对场景细节要求高,需多种特效库支持的特点,首次提出了一种基于Mantis的直升机视景系统的解决方案;该方案利用TerraVista制作精细的地形数据库,经转换后可采用大地形调度技术进行渲染;利用Creator制作三维模型库;采用内容定制文件配置场景中的实体和特效;采用Mantis Client和Mantis Server实现视景的渲染,最后通过基于通用图像生产协议的网络通信控制场景中的目标与特效;实际仿真结果显示,该直升机视景系统的仿真效果形象逼真,满足了实时性需求。

A scheme to develop scene simulation system of helicopter is presented based on Mantis for high requirements of detail and special effects. Large terrain are built by using software Terra Vista and rendered by large area scheduling technique. Models are built by using software Creator. Entities and special effects are configured by scene content file. Scene is rendered by Mantis Client and Mantis Server. Moving objects and special effects is controlled by network communication based on common image generation interface. It is shown that the simulation results are realistic and real--time.
