摘　　要：根据是否考虑液体粘性,对海浪绘制进行分类,并对无粘性海浪实时绘制展开综述。无粘性海浪的绘制忽略了液体粘性,绘制结果能体现风的影响,且绘制实时性好。无粘性海浪的实时绘制可分为基于规则波的方法和基于不规则波的方法,真实的海浪可以视为随机过程,因此基于不规则波的方法较之于基于规则波的方法更接近实际情况。提出基于不规则波方法中可能的改进:对基于不规则波方法中所用的海浪谱进行改进,使绘制结果能体现风速、风距的影响。According to whether the liquid viscidity is considered, we classify the ocean waves rendering and give a survey on real-time rendering of inviscid ocean. The rendering of inviscid ocean wave ignores the viscidity of liquid, the rendering result can reflect the influence of wind, and the real-time property of rendering is also good. The real-time rendering of inviscid ocean waves can be separated into two methods, the regular wave-based and the irregular wave-based. Actual ocean waves can bedeemed as the random process, so the irregular wave-based method is closer to actual situation than the regular wave-based method. The ocean wave spectrum used in irregular wave-based method is improved, this makes the wave to be rendered reflect the influence of the wind speed and the fetch length more. In addition, we also raise the possible improvements for the irregular wave-based method.
