The Research And Implementation Of Fireworks Simulation Technology Based On Particle Systems

Visual simulation of natural scenery is one of the most popular research topics inpractical application on virtual reality,including flame,cloud,rain,dust,spray,such as simulation and rendering of the dynamic nature and phenomenon,which is widelyapplied to weather forecasting,aeronautics and astronautics,decorating and other fields.Nature scenery has plenty surface texture and irregular surface shape,which can transformto random state over-time dynamically,therefore it is difficult to generate it by usingtraditional methods of modeling on computer graphics；how to simplify and efficientlysimulate such irregular nature and phenomenon becomes the key technology on generatingreal image of computer graphics. Particle system can well simulate the dynamic and therandom of the nature,and the advantage is that it is simple to construct complex objectsrealistically and real-time by using particle element,which is difficult to model by usingtraditional methods on computer graphics.In this paper,based on careful analysis and summing-up of the firework simulation athome and abroad,interaction,in need of visual simulation of natural scene,with thepurpose of friendly and better reality,designing and implementing a real-time renderingparticle system. The major points are following:First,we can make the mathematical andphysical models of particle. Second,we use the popular IDE,such as Visual C++,andthe graphic rendering SDK,such as Microsoft DirectX and OpenGL,to simulate thefirework in the nature. Finally,there are several methods to make the render moreeffective,and to be described in the paper.
