摘要: 粒子系统因其灵活性、适应性等特点,被广泛应用在景物模拟中。该文介绍一种基于粒子系统在火焰模拟中的应用,包括火焰粒子的初始化,帧数以及粒子属性的相应变化,体现粒子从产生、衰减到消亡的过程。为使火焰粒子更逼真,对粒子进行渲染处理,并简化公告板技术。实验结果表明,该方法可形象反映出火焰的动态变化,在普通微机上达到较好的仿真效果。

Abstract: Particle system has been widely used in modeling because of its flexibility and adaptability features. This paper introduces the application of particle system in the flame simulation, analyzes the general philosophy of particle system, introduces the initialization of flame particle, and the corresponding changes of the particle properties with the changing of frame, embodies the process in which the particles from beginning, attenuation to vanishing. In order to make flame particle more realistic. It exaggerates the particle, and simplifies the bulletin boards technology. Experiments show that this method can be used to reflect the dynamic change of flame vividly, and is simpler and easier to achieve better simulation results in an ordinary PC.



Key words: particle system, flame simulation, texture mapping, virtual reality
