| 摘 要： | 纳维-斯托克斯方程是描述流体运动的基础物理模型。首先简要介绍了在计算机上实现该模型的数值解算方法。在流体运动的计算机视觉仿真中,密度渲染才是最终结果,因此,又阐述了流体的密度场与速度场的关系,并且给出了流体仿真的基本流程。由于可编程图形处理器(GPU)具有并行性和速度快等特点,流体模拟的解算和渲染在图形处理器上运行更加高效,但是利用GPU编程实现流体仿真必须要实现3个核心转换,最后以支持3维纹理的Direct3D10为例,给出了利用GPU实现流体运动仿真两个简单实例。

| Abstract: | Navier-Stokes equations is a admittedly physically-based fluid dynamics model.A brief introduction on how to solve it with computers using numerical method was given.In computer fluid simulation,density rendering was our ultimate goal.Because of this,the relation between the velocity field and the density one was discusses and a basic process about fluid simulation and rendering was given.The parallelism and other characters of graphics processor made it more effective to perform the algorithm on graphics p... |
