摘　　要：提出基于GPU编程的真实感水面的优化实时渲染算法。介绍了各种水面渲染需要使用到的图形，数学处理技术。通过固定的顶点流实现了水波建模，凹凸映射贴图和纹理混合，水面的反射和折射等多种特效，并使用可编程流水线的补色渲染完成最后的水面绘制。实验证明该方法可以很好地模拟真实水面的渲染要求，可以满足3D游戏和动画中对水面渲染的需要。This paper presents the algorithm of Real-time realistic water surface rendering based on GPU. And also introduce the technic of graphics and mathematical used in water surface rendering. This algorithm accomplishes many effects such as water waves modeling through fixed vertex streams, bump mapping and texture blending, reflection and refraction by water, and so on. Then uses phone shading to render the scene. It is proved by experiment than this algorithm can properly simulate the water surface. It can be used in 3D games and Animations.
