摘要:

在针对船舶在海洋环境中航行进行三维仿真时, 船行波的仿真在实时性与渲染效果之间存在着很大的矛盾。 该文主要将船行波分成船首波与船尾波两部分,利用粒子系统分别进行仿真。 通过分析船舶尾流的几何特征,求解了尾流宽度与船宽和航速之间的关系,并通过粒子系统来搭建船尾浪的粒子运动模型,实现了船舶尾浪的模拟。对于船首浪,则简单地使用粒子系统建立粒子系统的运动模型来模拟船舶首部与海浪碰撞所产生的浪花破碎与飞溅等的效果。 并在Unity 中利用其自带的粒子系统进行了仿真实验,通过 VS2017 平台进行粒子系统的脚本控制。 通过仿真实验表明,该方法的实现简单, 并且在视觉上的仿真效果较为真实, 有着较好的实时性,适用于对实时性要求较高的应用场景。

Abstract:

When the 3D simulation of the ship waves in the ocean environment is carried out,there is a big contradiction between the real-time and the reality in ship waves simulation.? We mainly divide the ship traveling wave into two parts,the bow wave and the backwash,which are simulated respectively by particle system. By analyzing the geometric characteristics of the ship wake,the relationship between wake width,ship width and ship speed is solved,and the particle motion model of the stern wave? ?is built by the particle system to realize the simulation of the stern wave of the ship. For the bow wave,the particle system is simply used to establish its motion model? ? to simulate the effects of breaking and splashing caused by the collision of the ship爷 s bow with the waves. And through its own particle system, the simulation experiments are carried out in Unity, and the scripted control of the particle system is conducted through theVS2017 platform. Simulation shows that the proposed method is simple to implement,and the visual simulation effect is more realistic,with better real-time performance,which is suitable for application scenarios that require high real-time performance.
