Abstract


3D-animated simulation was a significant branch of computer graphics. In the computer animation simulation domain, to simulate the irregular fuzzy objective is a difficult and meaningful programs. Particle system is a kind of graph generation algorithm which can effectively simulate the scenery of irregular movement, been widely used in the simulation of irregular object movement, because of its flexibility, adaptability, etc. On the one hand, this paper expounds the basic principle of OpenGL, and implements the detecting-instrument dynamic simulation with flying objects in the sky, having applied light technique, terrain processing and the principle of 3D-combining graphics based on OpenGL. At the same time, it reflects the importance of 3D-animated simulations based on particle systems. With the background of blue-sky and terrain, this research realizes successfully dynamic simulation of flying objects location detecting-instrument, and have the meaning of significant military theories. On the other hand, it detail states the shaping dynamic fireworks simulation. Nowadays, to the shaping dynamic fireworks simulation still have no enough mature and have so much works to do. For instance, The rose fireworks in the festival days. On the 2008 Beijing Olympic opening Ceremony, the shaping dynamic fireworks simulation got more focus in the people’s eyes. In order to simulate the shape of fireworks going off, this paper is intended to illustrate the basic principles of particle system and conduct an in-depth research about the basic model of particle system for fireworks and the discharge principle, the traditional simulation model for the fireworks has been improved. In doing so, according to the simulation method of particle system, the paper attempts to explore and design the 8-word dynamic fireworks and the three-leafed rose of fireworks simulation based on VC++ and OpenGL. The key technology of shaping dynamic fireworks simulation is that control the moving traces of firework particles, compare to the function equation. After the explosion, the firework particles can combine the function graphics in the theories. Depend on the firework particles moving time. It products much little firework particles with the type, color, position, shape has been changing. As the background and firework particles have the same color, the little firework particles dead. The shaping dynamic fireworks disappearing, and use of texture mapping, color blending technology, etc. As the experimental result, in the night background of fireworks going off, the shaping dynamic fireworks simulation can create vivid images and come up to the real-time requirements. At the same time, improved the safety of production, reduced the cost of economy. It reflects the significant meaning in the fireworks technology application.
