The Construction of Cloud Model with Particle System

GUO Ye-min(Jilin International Business School,Changchun 130012,China)  
With the development of scientific technology and the wide application of the Internet,the simulation for irregular objects with computer graphics and virtual reality technology has been widely applied in the field of defense,meteorology and network architecture.The simulation for irregular objects such as cloud with particle system can greatly reduce the demands of 3D fidelity of model to computer configuration and reduce the difficulty of platform architecture.The randomness of the model constructed by the particle system makes the constructed model have a more natural visual effect,and a more rational physics structure can be applied in a wide range of areas.In this paper,the simulation for the cloud model of natural scenery is made through combining particle system with texture process function.In the concrete model drawing process,the simulation is realized by texture mapping and Billboard technology.Therefore,a new method of simulating irregular objects through the combination of one mode and multiple modes is proposed.
