| 摘 要： | 本文描述了一种利用基于Open GL三维纹理实现的直接体绘制方式显示流体模拟结果的方法。以JosStam的二维流体模拟模型为基础，扩展出三维流体模拟的模型；然后通过将密度场映射到三维纹理空间，实现实时的显示；并通过引入全局光照模型，得到真实感的渲染效果。最后通过与粒子系统进行对比，分析了本方法的显示效果优势。

| Abstract: | This paper describes a method of displaying the result of fluid simulation, with direct volume rendering based on 3D texture technology of OpenGL. After the 2D fluid simulation model of Jos Starn is extended to a 3D model, the density field of model can be mapped to a 3D texture space for the real-time rendering; then global illumination model is used to provide a .At last this paper presents a comparison between 3d texture method and particle system of rendering cloud and smoke, to analyze the advantage of our method in the effect of display. |
