Research And Application Of Display Technology On Simulation Platform Based On Game Engine

Realistic Simulation of natural scenes as a hot topic of computer graphics has been greatly concerned. Through the researches about that the simulation of the irregular object, people get many realistic, real-time simulation method of the natural scenes. In recent years, more and more researches are carried out on sandstorm simulation; the sandstorm as a type of disastrous phenomenon occurs frequently brings people with serious consequences, and caused widespread concern in society. The real-time simulation that based on particle system method of sandstorm phenomenon is displayed in this paper. The study in the thesis is as follows:Firstly, the current situation of sandstorm simulation in domestic and foreign has been studied. The researches on sandstorm simulation are mostly focused on post-treatment effects or animation processing, real-time simulation receives much less attention.Secondly, some display technologies that are applied in the game engine has been studied in this paper. And the simulation of irregular objects especially the particle system and the theory of particle system are researched and analyzed. This paper distills the information about sandstorm including appearance properties and movement format about sandstorm, then gives the sandstorm particle system model.Finally, simulation of sandstorm phenomena based on the Ogre-Engine and particle script has been designed, and realizes the real-time simulation effect in 3D virtual scene with the LOD, Billboard and Texture rendering technology. Simulation obtained a good realistic effect and its rendering speed is stable and fast.In conclusion, particle system is used for the simulation of sandstorm phenomena, achieved a good real-time simulation effect. The simulation of sandstorm has important practical significance in real life, especially in military training, virtual reality, game field, urban planning, and public transport and so on.
