Firework Simulation Based on Particle System on GPU

Aerodynamics and particle dynamics were employed to investigate the conformation of firework, and several parameters were distilled to control the appearance of firework expediently. Besides, the structure of GPU based particle system was analyzed, and a memory structure double texture buffer was proposed using to fully exploit the parallel computational capability of GPU. Based on these, a fireworks particle system model which achieved the real-time simulation of fireworks on PCs was proposed.
