Research And Implementation Of Virtual Battlefield Environment Based On Unity3D

In recent years,with the increasing impact of information technology on the modern military field,the research of virtual battlefield environment is becoming more and more important in the military field.According to the current military situation and the development of the information field,the creation of virtual battlefield environment based on Unity3 D engine is studied in this paper.The main contents of this study are as follows:Firstly,according to the contradiction between the scale and frame rate when the real terrain of virtual battlefield environment is rendered dynamicly,the high-precision terrain environment of the virtual battlefield is constructed by adopting the LOD algorithm combined with the real DEM elevation map data.In the virtual battlefield roaming system,the frame rate of the battlefield scene roaming is improved to some extent by combining the visual elimination technique and the detail level model technology.Secondly,aiming at the fact that the physical model of rain and snow is low in reality based on the conventional modeling method,the physical model of rain and snow is simplified on the basis of particle system.Its motion state is reduced to equal acceleration motion.In order to further improve the authenticity of rain and snow motion,random perturbation is carried out in the course of particle motion.The size of the rain and snow is rendered by real-time control of the region and number of particles produced.The simulation of smoke diffusion in explosion scenes is achieved by linear interpolation combined with Billboard algorithm,it can effectively improve the rendering efficiency.Thirdly,the motion system of vehicle CGF entity is realized by using TankTrackSimulator framework combined with pathfinding algorithm.By combining the ray and the collision detection,the visual perception and auditory perception of the CGF entity are realized,so the CGF entity can gain the real-time information of the virtual battlefield.According to the information obtained,the CGF entity can process the information by combining FSM with the autonomic behavior decision system.At last,the basic model of battlefield environment is completed by 3D Max,and the virtual battlefield environment is constructed on the Unity 3D platform.The Gizmos system of Unity3 D is used to test the CGF entity intelligent system.The test results show that the system can achieve effective behavior decision.
