摘要
模拟河流和湖海等大面积水域本身就是个具有挑战性的问题,尤其是对具有复杂河网的河流的三维仿真。针对具有多个交汇点的复杂河流的仿真,在Hendrickx提出的实时河网渲染的基础上,提出了一种基于Bézier曲线和法向贴图的三维河流仿真改进方法,改用一种快速三角网相交检测方法提高了河流的渲染速度,同时在GPU架构上实现了河水的渲染,显著改进了其效率。
The simulation of rivers and lakes with large scale and scope water is a challenge, especially for three-dimensional river simulation with complex river network. Focusing on complex river simulation with multiple junctions of river network, an improved three-dimensional real-time river simulation method is proposed based on Bézier curves and normal map of river flows according to Hendrickx ＇ research results. However, the original method presented by Hendrickx uses a simple and violence comparison method for intersection detection of triangle river networks. A fast triangulation-intersection-detection method is employed herein to improve the rendering speed of river, and meanwhile, the rendering of river water is realized by using GPU technology. The result of simulation shows that the rendering and running efficiency has a significantly improvement.
