Recently,simulating natural phenomena has become one of the most important research areas in computer graphics.We focus on the visual simulation of fire.First,we propose an interactive method to simulate the motion of fire.Our method allows the user to control the shape and motion of fire.This is achieved by combining cellular automata and particle systems.Secondly,we propose a fast rendering method using wavelets for surrounding objects illuminated by the fire.The method can take into account not only direct light but also indirect light.This method achieves fast calculation of dynamic intensity and render shadows for objects illuminated by fire.Using this method,realistic images of a scene with fire can be generated in real-time.
