针对目前河流仿真所存在的计算效率低,渲染效果不够真实的问题,介绍了一种基于物理规律的河流实时仿真的方法.提出了一种Poisson圆盘分布的算法,可实现屏幕空间的优秀的分布样式,该算法产生的分布粒子用于表达河流的速度场,进而重构河流表面;采用一种纹理精灵的技术,通过纹理的动态访问和纹理混合,有效地实现河流表面的渲染.仿真实验证明:该方法可以产生渲染效果非常逼真的河流视景,并能够满足实时仿真的要求.
In view of the low computational efficiency and the unrealistic rendering effect of current river simulation, a method of river real-time simulation based on physical laws is introduced.A Poisson disk distribution algorithm is proposed, which can achieve excellent screen space Which is used to express the velocity field of the river and reconstruct the surface of the river, and to use a technique of texture elf to effectively render the surface of the river through dynamic texture access and texture blending. Prove: This method can produce a very realistic rendering of the river scene, and can meet the requirements of real-time simulation.
