Abstract：The elementary theory of the particle system coincides with the objective laws of the natural world. As a result, the particle system can be used for fireworks and other complex phenomena simulation. To solve the problem that the simulation of particle system is of huge computation and memory resources consumption, the paper built the basic particle system model based on Compute Unified Device Architecture (CUDA) framework. The storage and movement update of particles in the model were considered. Then the parallel KD-TRIE neighbor particle search algorithm based on CUDA was studied. Finally, the detailed implementation of the fireworks simulation was discussed based on the CUDA particle system. The results show that the model can simulate the rise and bloom of the fireworks realistically with the frame rate of up to 320 frames per second, enhancing the fidelity and real-time performance of the simulation.
