Design and realization of virtual simulation training system for certain type artillery radar

There are many difficulties in the process of the training for the artillery radar's position selection, such as training field is limited, the evaluation method for training is laggard. To resolve the problem, a virtual simulation and training system was designed based on Virtual Reality technology. This system developed with tools of OpenGL, Multigen-Creator, VC++6.0, and created a 3D scene with the DEM data of digital map. The system simulated virtual equipment of artillery radar, special effects of rain, snow, and fog based on collision detection technology and particle system technologies, and formed a realistic virtual battlefield environment, and composition structure, function module and key technologies of the system were discussed. Accordingly, the system implemented all the functions of scenario edit, scene display, position selection training and training evaluation.
