基于粒子系统的Direct3D火焰模拟改进算法
An improved Direct3D fire simulation algorithm based on particle system
摘要
Abstract
It is difficult to accurately describe the dynamic characteristics of an irregular uncertain on the flame,an improved algorithm for simulating real-time fire based on classic particle system is presented.Firstly,when new particles are initial-ized,a hemispherical flame particle emitter is designed to optimize their positions.Then,in order to increase time perform-ance,five color models are required to simplify those complex actions of fire by Nguyen′s blue core model,and the midpoint wizard of Direct3D technology is used.To solve the problem of the reality of flame simulation,dynamic motion fields are hi-erarchically controlled to realize the dynamic change in flame shape,and alpha blending levels of the flame in different colors mixed are started.Experimental results show that the real-time and reality are optimized,and the performance is significant-ly increased.关键词
