Research And Realization Of 3D Flame Simulation Model

The simulation of the natural scenery in computer graphics occupies a very important position, and the use of the three-dimensional simulation of the natural landscape in arears such as computer games, film special effects, virtual reality may become more and more frequently. The virtual simulation methods commonly used fractal geometry method, texture mapping method, particle systems.Fire simulation is a important research aspect of natural scene simulation. This article realize the simulation of the reality flame from video textures,particle system two ways, and put forward how to synthesis video textures from a few flame video paragraphs,how to build 3D flame model from video textures. The particle motion of the flame particle system was analyzed, with simplified particles force analysis, established the flame particle data structure,initialized the particle properties. Finally, comparing and summaring the two simulation methods.Video textures made in recent years, which is between kinds of images and video between the new media, has both the advantages of the image, another dynamic video scene. In this paper, video textures of thought, a real fire on the same scene shot from different angles, eight out of eight video samples of these samples for further analysis, and associated processing synthesized eight out of the flames of an infinite continuous video textures, then this 8 Duan video texture on the texture mapped to a sphere. Due to the continuous movement of the flame shape, as well as three-dimensional scene in perspective constantly changing, the need for the relevant texture synthesis. At the same time and we are the flame of the main paragraphs of video modeling to simulate the spread of fire effects to achieve real material to meet the special effects to change the interaction.
