摘　　要：针对海上救助作业模拟训练的要求,有必要将救助作业的可视化仿真引入救助船模拟器的视景系统中,其中撇缆作业是船舶拖带救助的重要工作之一。本文在基于Vega Prime开发的视景系统中引入Open GL,通过事件公布订阅机制实现二者的混合编程,在此基础上采用基于能量守恒的内弹道模型与基于空气阻力外弹道模型,实现弹体运动与弹道轨迹的可视化仿真。仿真视觉效果形象、直观,弥补了单独使用Vega Prime在特定效果可视化仿真中的不足。According to requirements of the simulated training of the marine rescue,it is necessary for the visual system of rescue ship simulator to introduce the visual simulation of rescue operations in which the line-throwing operation is one of the most important works when doing the ship towing rescue process. In this study,Open GL is introduced into the visual system developed with Vega Prime,and to achieve that,the hybrid programming is implemented by using the event issued subscription mechanism. On that basis,the visual simulation of the projectile＇s motion and ballistic trajectory is achieved by utilizing the internal trajectory model deduced from the energy conservation and the external trajectory model taking the air resistance into account. In consequence,the simulation effect is vivid and intuitional,and it overcomes deficiencies of the exclusive usage of Vega Prime.
