摘要
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Windows XP环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。
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.
