Flame simulation on the particle system is the important part of visual environment.At present,some flame simulation methods are confronted with the shortcomings such as time consume and low reality in image.This paper,presents a simulation method of three-dimension flame based on particle system,and is realized by GPU.The basic idea of the method is that the flame movement in the true life was analyzed by physics dynamics,then flame particle system model was constructed and 3D effect of flame was implement...
