Simulation Of 3D Effects In Battlefield Environment Based On Particle System

The army's combat training is very important now, and the simulation of the real battlefield environment is of great significance.Two-dimensional information has been unable to meet the demand at present. With the development of virtual reality technology,three-dimensional (3D) simulation of the battlefield environment is possible. In the simulation of 3D battlefield environment, in addition to the terrain, combat personnel and the combat tool, the simulation of explosions, fire, smoke and other effects is also very important, since these effects can enhance senses of realism and immersion of the 3D scene. However, these special effects are irregular objects, which make it difficult to simulate with the general geometry. Therefore, the simulation of irregular objects is always a hot and difficult research topic in computer graphics. In the past few decades, various simulation algorithms have been proposed, but so far, the particle system is considered to be the best algorithm for the simulation of irregular objects,and has been widely used in many fields, but the application in simulation of three-dimensional effects in battlefield are rare and the simulation technology is not mature.The main work of this paper has four sections which I will give introduction in the following.First, this paper based on particle system algorithm. Through in-depth study on the basic principle of particle system theory, this paper gives the general formula of the particle properties. This paper also discussed particle system model from the "birth" of particles, particle properties, real-time change of particle, particle "death" the 4 processes.This paper gives the modeling method of particle system from two aspects of sharing the structure of the particle system and the basic algorithm, and then explain the basic theory of particle system in this paper.Second, the analysis and summary of the methods of using OSG and OpenGL graphics library. In order to facilitate the management, in the actual implementation method, this paper divides the whole system into four modules, respectively is: the particle system module, particle module,texture mapping module and stress field module. This paper gives the usage of each module and the data structure of each module.Third, ultimately simulation results of the corresponding graph,explosion, flame, smoke, is given. This paper also applies them to 3D battlefield scene.Fourth, this paper uses he GPU 4K super multi view real-time 3D video conversion method based on the naked eye 3D display to achieve 3D display of the battlefield scene. Three dimensional scene is expressed as "video + depth" data format in the algorithm, virtual viewpoint rendering synthetic 3D video depth map using the map and the corresponding point of view. While this paper also adds a simple man-machine interaction function, to achieve a more realistic and immersive 3D battlefield environment simulation and the stereoscopic display;The computer configuration is: Inter (R) Core (TM) i7-4700MQ CPU 16G NVIDIA Quadro @ 2.4GHz; K3100M, the size of the naked eye 3D displays is 50 inches, resolution up to 3840 * 2160, 28 point of view. The experimental results show that our algorithm is effective and feasible, and it will be widely used in the simulation of complex objects and auto-stereoscopic display. In this paper, the particle system algorithm is further optimized and expand the application range of particle system algorithm.
