Flame simulation in computer graphics has been the most challenging problems. According to the key problem of real time and reality in flame simulation based on particle system, a new flame model based on improved particle system and the texture mapping is proposed in this paper. This article uses specific geometric shape as the elementary particles and combines treatment of derivatives based on the flame of the original particle system to simplify some of the dynamic equation, to reduce the difficulty of computational modeling and improve rendering speed; Through texture mapping and particle mixing effects to achieve flame changes color in different regions and reflect the temperature difference between them; In addition, the method also reflects the dynamic field of the particle system.
