航海仿真虚拟环境的海浪视景生成技术

Wave Simulation Technology Applied to Virtual Environment of Navigation Simulation

分析了海面浪花的生成条件,用粒子系统和图象合成相结合的方法,实现了动态海面及海面浪花的实时仿真。在模拟船舶周围浪花时,作者提出了椭圆模型,可方便地确定粒子的随机初始位置,通过调整粒子在椭圆上的限定范围,可用同一粒子系统,分别模拟出船体首部、尾部以及其它部位的兴波,并给出了粒子各属性的确定方法。

The paper places emphasis on analyzing the generating condition of sprays on sea and implementing the real-time simulation of dynamic sea, sprays and ships wakes. The ellipse model applied to simulate sprays around ship is convenient for the user to locate the random initial position of each particle in particle system. The same particle system can simulate waves near ships bow, ships stern and other sections by adjusting the limited scale of particles on the ellipse. The paper also introduces how to define the various properties of each particle.
