实时水面模拟方法研究

Research on the Method of Simulation of Real-Time Water Surface Based on GPU

提出了一种基于GPU的水面实时模拟方法。该方法不依赖于噪声图,而实现了实时的水波生成、折射和反射效果的菲涅耳合成以及水面光照模型的计算。利用GPU在片段处理前的光栅化处理,该方法渲染负荷不会因水面大小和精度而增大。且依赖GPU的高速计算能力,方法可以达到实时。

A method of real-time water surface simulation based on GPU is proposed. Using this method real-time water wave can be constructed without displacement texture, and then be rendered with the Fresnel effect and the illumination model. As the rasterization is done before the fragment processing of GPU, the burden of rendering will not grow with the size and precision of water area. According to the GPU’s high capability of calculating, this method can achieve the real-time rendering.
