In order to reproduce the actual battle scenes in real time,the 3D real-time battlefield scene has been built in this paper based on the theory of particle system,and the combination with OSG and MFC technology.According to the ballistic fire control solver parameters,this paper has simulated realistically the whole process of the shells from the bore to hit the target,including the smoke fire from muzzle at the time of artillery shells' colliding,the trajectory of artillery shells,explosions after artillery shells hitting the target.This 3D real-time scene rendering technology has successfully solved the conflict between realistic simulation of particle system and real-time nature,modified the traditional two-dimensional observation that make command and operations staffs getting immersive visual experiences.In the future information warfare,it will offer an important significance.
