摘　　要：海浪场景的建模是数字海洋的重要组成部分。本文用随机数模拟海浪,海浪的位置大小和波动都是随机的,海浪在涌向岸边的过程中随机生成新的海浪。海面反射光用Phong光照模型模拟,求出关键点得到太阳在海面的映像。该模型生成的实时3D大尺寸光照海浪模型在运动中不会重复,适合海面的数字化再现和海洋要素的仿真。The modeling of ocean waves is an important part of digital ocean modeling. This paper uses stochastic number to simulate ocean waves, so the location, size and undulation of ocean waves are stochastic, and new ocean waves are created randomly as ocean waves move toward the coast. We use Phong illumination model to simulate reflected light of the water surface, and calculate critical points to model the images of the sun in the water. The animated large-scale 3D illumination ocean waves scene generated by this model will not repeat during movement. It is suitable for digital reappearance of the ocean and modeling of ocean elements.
