Abstract: Based on the analyses of complex modeling characteristic with special fireworks, this paper puts forward a multiparameter simulation function. Through different parameters combination, a variety of special fireworks simulation could be realized. And some special fireworks simulation was carried out using the multiparameter function based on particle system, the results show that a variety of special fireworks simulation can be easily completed. By taking the actual scene images as background, the very good special fireworks simulation effect was obtained.
