导弹投射区可视化中的数据模型设计

Data Model Designing in Missile Shooting Area Visualization

导弹投影区域可视化是实现投射模拟训练及匹配基准图制备的关键环节。为实现导弹投射区域的可视化,通过对现实世界进行抽象与简化,设计了导弹投射区三维场景数据模型。该模型将三维场景划分为地形、目标、显著地物群三层,每一层采用或设计了相应的数据结构;在介绍相应数据的准备方法并准备好相应数据的基础上,实现了分层场景的绘制。系统应用表明该导弹投射区三维数据模型,规范了作战保障信息,使场景绘制工作更为灵活和有效。

Missile shooting area visualization is very important to achieve shooting simulation training and prepare reference map.In order to visualize missile shooting area,by abstracting and simplifying the realistic world,designed the 3D scene data model of missile shooting area.The data model separated the 3D scene to terrain,target and notable group upper object three part,every part used or designed its data structure.After introduced the method of preparing involved data and prepared involved data,accomplished the building of ayered scene.The layered data model is proved flexible and effective in application.
