A Speedy Simulation Method of Naturally Burning Flame

To decrease the computational complexity in the simulation of flame,according to the phenomenon of naturally burning flame,its speedy simulation technique is proposed by using object-oriented method.First,after the forming principle of dynamic burning scene is analyzed,two models for blending flame image and background image are provided,and two color models used for flame simulation are also presented.Then,the object-oriented models of flame particle,tongue of flame,and flame system are described,and the fast implementing technique of burning behavior of each object is offered too.Next,the technique for realizeing the dynamic flame and its algorithm are discussed.Finally,the experimental results,which show that the proposed algorithm is accurate,speedy,and effective,are illustrated.
