摘要/Abstract

摘要： 巨浪的真实感绘制是计算机图形学的热点和难点之一。从浪的物理特性出发，绘制出较逼真的大规模实时卷浪场景。将卷浪的模拟分成基本波面和卷曲波面模拟。首先基于三维Gerstner海浪模型，加入Perlin噪音扰动来构建海浪的基本造型；然后采用基于物理的NURBS卷浪曲面生成算法，构建3D卷浪曲面库；随后动态搜索波面波峰，用卷浪曲面取代海面波峰，将卷浪曲面与初始波面无缝拼接；考虑不同风速与浪的交互作用，并采用相关真实感绘制技术，最后实现了不同情况下的大规模卷浪场景。

关键词: 卷浪, 真实感建模, 波峰, 实时绘制

Abstract: Photo-realistic simulation of curved wave is one of the hottest and the most difficult tasks in computer graphics.The paper can render photo-realistic curved wave based on physical features of ocean wave.The simulation of curved wave is divided into two parts.One is rendering common ocean wave surface，and the other is rendering the curved portion.Firstly Perlin noise is introduced into 3D Gersterner wave to generate the basic 3D wave surface.Then the surface sequences of the curved waves are generated based on NURBS surface.Based on the method of seeking wave crests dynamically on common ocean surface，these wave crests are replaced with the NURBS curved surfaces seamlessly.Finally，considering the interaction between various wind speeds and waves，and using some realistic rendering technologies，the realistic curved wave ocean scene is generated in real-time.

Key words: curved wave, realistic modeling, wave crest, real-time rendering
