基于粒子系统的喷泉模拟实现

喷泉效果可以大大增强虚拟现实系统的沉浸感，粒子系统是实现喷泉模拟的有效方法。为了实现喷泉的实时模拟，本文构建出一种基于粒子系统的喷泉模型。通过分析模型中粒子的属性及其变化，加入风力和阻力等外界因素，实现粒子在复杂受力环境下的实时动态模拟，并采用纹理色彩融合技术来绘制粒子。最后，以VC＋＋6．0为编程工具，OpenGL为动画环境，在WindowsxPG境下实现了喷泉特效的模拟。实验证明该算法模拟的喷泉效果满足实时性和逼真性的要求。

Simulation and realization of fountain based on particle system

The effect of fountain can consumedly enhance the immersion characteristic of virtual reality system, and particle system is an effective method in fountain simulation. To implement three-dimensional fountain simulation, a new fountain simulation method based on particle system is proposed . The attributes and changes of particle are analyzed in this particle system, and wind, resistance are also added to draw a three-dimension foundation that object to complex environment. It also uses the color blending to draw the particles. At last, making use of tools such as VC＋＋ 6.0 and OpenGL, the full system was developed on Windows XP operating system. The result of the simulation demonstrates that the method can meet the requirements of real time and reality.
