| 摘 要： | 针对三维海洋仿真中舰船航迹再现的实时性与显示效果之间的矛盾,提出了一种应用水波弥散特性的可视化新方法.该方法将水面波的弥散特性应用到船首产生破浪的运动建模中,建立了简化的船行波粒子系统模型;然后根据船尾航迹的宽度距离扩散规律,建立了尾部航迹的粒子系统模型,并采用后续渲染技术实现跟海面的融合;最后基于开放场景图粒子系统,在VS2005平台对新方法进行具体实现.水声对抗仿真系统中的实际应用表明,新方法更符合物理运动规律,对整个系统帧速的影响小于1帧/s,有更好的实时性和显示效果.

| Abstract: | A new visualization method for ship wakes applying dispersive nature of water wave is proposed to solve the contradiction between real-time and display effect in ocean scene simulation system.The surface dispersive nature of water wave is used to establish the motion model of bow waves,and then the bow wake's particle system model is built.The shape-like particle system model is built based on the distance-width spread discipline of stern wake,and the post-rendering technique is used to merge with sea surfa... |
