Abstract: 实时海面航迹仿真对仿真效果的真实性和实时性都有较高要求,在仿真区域较大、粒度较细的情况下,二者往往难以兼顾。针对以上问题,提出一种基于CUDA并行处理的海面航迹仿真方法,采用海面网格和水波粒子虚实相结合的方法来生成海面航迹,并将所有核心计算和渲染在GPU中并行执行。实验结果表明,CUDA方法能够充分发挥GPU并行处理能力,大幅降低内存和显存通信,在保证仿真效果真实度较高的情况下,显著提升实时仿真效率。
English Abstract: The real - time simulation of ocean surface and ship wakes need for high level reality and real - time visualization. It is hard to give attention to both points and gain excellent performance. Aiming at these special characteristics,a CUDA based parallel approach has been put forward. The ocean surface and ship wakes simulation were implemented by an integrate method of real grids and virtual particles. All of the core computing and rendering work were executed in GPU in parallel mode. The result shows that this approach performs well and can improve the efficiency greatly.
