With the rapid development of computer technology and space modeling technology,dynamic 3D scene modeling has become a hot research topic in the fields of computer graphics,virtual reality technology,3 dimensional games and so on.On the one hand,with the improvement of the user's demand,high quality dynamic simulation has become the key technologies to enhance the user experience.On the other hand,along with the rapid development of military simulation,3D modeling technology,real flame model constructing became a technology can be achieved.Therefore,the establishment of interactive 3D visualization of the dynamic flame has already became the common expectation of the visual field.In this paper,we research from the method of different flame modeling,deeply explored the principle of flame simulation method and put forward a three-dimensional interactive missile tail flame research method based on particle system.In the research,we focus on the modeling feature of the flame model,combined to the model of the scene.The main research contents are as follows:The first step,we analyzed the existing main flame modeling method.And we also analyzed the fractal method,construction method,grid method and the Lagrange method according to the different motion control characteristics and flame forming method.In this paper,we introduced the principle of particle system,the main modules of particle system.We analyzed the process of particle system,and summarized the contribution of particle method to the whole experiment.The second step,according to the idea proposed in this paper,we simplified the equation of fluid mechanics.Specific analyzed the whole process.Taking control of the particle's motion based on the theory of fluid mechanics to meet the requirement of laws of fluid motion.we used the particle system to simulate flame and construct the physical flame model.And the control of the whole 3D flame model is carried out from four aspects such as particle initialization,particle emission,particle control and texture mapping.The third step,we lead the particle system into three-dimensional roaming system,introduced the skybox to layout the scene,and joined the camera roaming system to achieve human-computer interaction.On the basis of this,the MilkShape3 D missile data model is introduced,and the model is seamlessly connected to the scene,which is completely matched with the injection process of the three-dimensional missile plume.Finally,we elaborated the detail of the system framework,compared the simulation results with the real missile plume.And compared the simulation data with the related research,analyzed the reasons of experimental data.By comparing and researching experimental results,our simulation method significantly improve the rendering efficiency.At last,we summarized the advantages and disadvantages of the experiment.
