Irregular Object Simulation And Realization Based On Particle System

With the computer hardware and software technology's rapid development, making the technology of irregular objects simulation by means of the computer has been infiltrated into every corner of people's daily life, but also promotes the development of computer animation technology. Computer animation technology is now widely used in aerospace, entertainment, computer games, three-dimentional animation and other fields, there are broad prospects for development, therefore the simulation of irregular objects becomes more important, however, because of irregular objects with irregular, random, and inherent uncertainty, it is difficult to describe using traditional modeling methods and techniques, particle system is considered as a more successful method for the simulation of irregular objects, causing widespread concern at home and abroad to learn and study. In this article, two representative irregular objects, fountains and waterfalls are simulated, based on OpenGL graphics software interface and the particle system, the main work of this article is as follows:[1] Describe the research status of particle system at home and abroad. The basic concepts and basic ideas of particle system are described in detail, and the research proceeds on that basis. Master the methods and steps using particle syatem to model, and summary and conclude on the basis of previous.[2] Particle system theory and the model will be applied to simulate natural landscape fountain. When we determine the particle properties, we usually choose some properties refer to the characteristics of the movement of fountain particle, to large extent, save the time cost of system. Establish the fountain system model accurately, simulate various forms of fountain by adjusting the initial position of the fountain, tranche, spray angle, vector product and other factors, the simulation results have a good realism and real-time.[3] Implement the simulation of waterfall using particle system model. After analyzing the forces in the process of the whereabouts of the waterfall particle, we introduce the wind to simulate waterfall, and simulate waterfall effect chart both having no wind condition and having wind condition, then we obtain that the role of external forces will have some impact on the simulation results, experimental simulation results have a good realism.[4] This paper achieved the simulation of two irregular objects mentioned above in the Windows XP Operating system environment using VC++6.0 as programming tool and OpenGL display lists and texture mapping techniques, experiment obtains a good simulation result.
