The Simulation And Realization Of Fountain Based On Particle System

Simulation of natural scenery is a hot research branch in computer graphics, which is widely applied to television advertising, real-time rendering, 3D animation and games, upholster design, virtual scene and so on. It plays an important role in the information society with its unique charm. The shape of most natural landscape, such as flame, spray, rivers, waterfalls, rain, snow, fog etc, is changing stochastically, and it is difficult to model and visualize these natural sceneries by using traditional methods of modeling and simulation, so the simulation of natural scenery is also a challenging task.Based on a careful analysis on the previous related work and considering the demand of virtual scene for video game, the system develops a real time algorithm of virtual fountain motion, the work and results are as follows:Based on the analysis of the motion of fountain, motion fields of fountain are simplified to wind and gravity fields to improved the system's real time simulation. The system uses the irregular motion of random particles to simulate the fountain particle, which makes the fountain movement more flexible and realistic. The system enhanced the simulation of the sprays and water waves of the fountain.The system uses polygon to render fountain instead of classical dot particles, which makes run-time further decreased. Furthermore, the system uses texture mapping technique and particle tracing technique to enhance the render quality.Finally, by using Visual C++6.0 as the programming tools and the three-dimensional animation is supported by OpenGL, the full system of three-dimensional fountain simulation based on Particle System is developed on Windows XP operating system and effect of simulation looks realistic.
