摘要
研究海洋场景中海浪等视景的实现,是计算机在图形学中的具体应用。风浪是海洋表面最主要的一种波浪,从海洋学已有的统计观测结果出发,利用海浪频谱与方向谱的相关公式,对开阔海面深水域由风引起的海浪进行定量分析。利用粒子系统对雨、雪、云等自然现象进行仿真,实现了对海洋场景的实时显示。在VC平台上用OpenGL开放图形库实现了所述海洋场景的仿真。实践证明,提出的方法在实时性与真实感方面均取得了不错的效果。
The realization of ocean wave is the application of computer graphics in simulation of ocean scene. Wind - driven wave is an important phenomenon of ocean surface. Quantitative analysis of ocean wave was given by using frequency spectrums and directional spectrums based on the results of statistics and observations of oceanogra- phy which is presented in a deep and fully developed sea. Rain, snow and cloud can be simulated with particle sys- tem, which is useful for the simulation of ocean scene. The simulation of ocean scene was realized on the platform of VC and OpenGL. The results show that the method acquires satisfied effects in real -time and third dimension.
