The dynamic fireworks simulation based on particle systems(PS) is studied. Firstly, this paper introduces the particle system and gives out the basic model and processing procedures to simulate dynamic natural objects with the PS method. The data structure to simulate fireworks is proposed by analyzing the details and the characteristics of fireworks. Secondly, a dynamic fireworks simulating algorithm is presented in detail, which mainly discusses the fireworks′ characteristics, such as color, brightness, transparency, shape, size, trail and life etc., and the simulation of special displaying effects such as mousing, spinning and star. Finally, the dynamic fireworks simulation on the background bitmap realized with the OpenGL technology is given.
