利用OpenGL实现舰船损害管制虚拟训练舱实时操作的方法

Realization of Real-Time Operation Method for Virtual Warship Damage Control Training Hull Based on OpenGL

根据舰船损害管制指挥训练系统需求,构建了虚拟舱体模型数据库,定义了基于四边形面绘图模式的舱体模型数据结构,给出了模型面的着色方法和舱体组成单元的标识规则,运用OpenGL库函数绘制了舱体模型。叙述了改变舱体面颜色和隐藏部分舱面的技巧,讨论了模型平动、转动、缩放以及视角变换等操作的程序实现方法和步骤,提供了一种灵活构建可操作三维模型的方法。

According to the demands of warship damage control command training system, the database of virtual hull model is constructed, the hull model structure based on the quadrilateral plotting mode is defined, the rendering method of model face and marking rules of hull units are presented, and the hull model using OpenGL functions is drawn. The skill of changing model face color and hiding parts of hull are described, and the steps and methods of realizing operations such as model moving, rotation, zooming and visual angle switching are discussed.
