Abstract: On the theoretical basis of the particle system with an investigation of various new research results and application methods in recent years, this paper presents an efficient flame simulation method based on the texture slice. The method uses suitable texture slices with less transparency, to render the flame procedure by a rotation loop. Furthermore, the simulation steps and different flame environment constructions have been given. The analysis shows that the texture slice method possesses advantages in various aspects and has potential in many application fields. Finally, the actual computer simulation results are presented in the paper.
