摘　　要：提出基于可编程图像硬件实时生成真实水面的渲染方法,通过实现水面建模、水面折射和反射完成整个渲染过程。在正弦波叠加的同时,利用2个凹凸纹理实现水面的动画效果,通过实时纹理映射技术实现水面的反射、折射和菲涅尔等水面光照效果。实验证明该算法能够很好地满足人们对真实感和实时性的要求,适用于虚拟现实中真实水面的生成。This paper presents an algorithm to generate and render water surface in real-time based on programmable graphics hardware. The algorithm completes the rendering process by realization of water surface modeling and reflection and refraction of water. It models the water surface based on sine wave overlapped, using tow bumping-maps to achieve action effect of the water, realizes the reflection, refraction and fresnel illumination effects with texture mapping. Experimental result shows the algorithm meets the photorealism and real-time requirement very well and can apply to the generation of photorealistic water in visual reality.
