【摘要】 对短时间尺度内的点源瞬时溢油进行研究,将溢油过程分为油膜自身扩展和油膜漂移、扩散两个阶段,分别用椭圆模型和油粒子模型计算溢油的轨迹。采用基于海浪谱的快速傅立叶变换方法绘制大规模海面。利用粒子系统方法实现油粒子模型。提出利用平面反射技术实现海面溢油的三维可视化,即将溢油平面轨迹渲染为纹理图,再将纹理图通过反射技术映射到海面上。提出的方法已成功应用在航海模拟器的溢油事故模拟中。更多还原

【Abstract】 The early process of instantaneous oil spill was divided into two stages: oil spread, oil drift and dispersion, and the track of each stage was calculated using the respective mathematical model. The fast Fourier transform method based on wave spectrum was developed to render the ocean surface. The particle system was used to implement the oil particle model. The planar reflection map was adopted to render oil spill on the simulated ocean. The track of oil spill was generated to a texture which was projected to ocean surface. The method developed has been applied successfully to simulate an oil spill accident in the marine simulator.更多还原
