针对以往舰艏浪三维可视化中仅从实际观察出发建立动态模型，不能反映舰艏浪物理运动规律的问题，提出一种基于物理模型的舰艏浪三维可视化方法。该方法将舰艏浪物理模型应用到三维可视化中，采用边界元方法计算得到舰艏浪外形数据，利用粒子系统技术建立了三维动态模型，基于OpenSceneGraph粒子系统，在VS2010平台上实现了舰艏浪的三维可视化。实验结果表明该方法更符合物理运动规律，能较好地模拟舰船航行时的艏浪。
針對以往艦艏浪三維可視化中僅從實際觀察齣髮建立動態模型，不能反映艦艏浪物理運動規律的問題，提齣一種基于物理模型的艦艏浪三維可視化方法。該方法將艦艏浪物理模型應用到三維可視化中，採用邊界元方法計算得到艦艏浪外形數據，利用粒子繫統技術建立瞭三維動態模型，基于OpenSceneGraph粒子繫統，在VS2010平檯上實現瞭艦艏浪的三維可視化。實驗結果錶明該方法更符閤物理運動規律，能較好地模擬艦船航行時的艏浪。

According to the problem that the physical motion law of the ship’s bow wave can not be reflected for building the 3D dynamic model from the actual observation in the former 3D visualization, this paper proposes a new 3D visualization method for bow wave based on physical model. The bow wave physical model is applied to the 3D visualization, and then the bow wave shape data are calculated by using the boundary element method. The 3D model of the ship’s bow wave dynamic model is built based on particle system. The 3D visualization of the bow wave is realized on VS2010 platform based on OpenSceneGraph. The experimental results show that this method more accords with the law of physical motion and can well simulate the ship’s bow wave.
