| The artillery firing command is the very important contents to the artillery combat command. It's efficiency will affects the effieciency of the combat command largly, even the final result of the war. It is the current tendency to ultilize the virtual training platform to improve the commander's capacity to control the war. The paper is trying to improve the standard of our artillery virtual training system.The paper introduces the current status and the development history of command training and virtual reality. The application of virtual reality in the command training is also introduced, and the significance of virtual reality for artillery combat command is points out.On the basis of studying the normal ways of creating virtual environment, an algorithm to render the terrain based on image-drawing is presented.According to the characteristic of the general virtual environment of artillery command training (GVEACT), computer generated forces (personnel), the visualization of projectile's flight course, the influence of crater to transit and frags spreading and its damage to human are researched and developed. The motion of the virtual human is achieved by a way of combining kinematics with key frame. By the motion model,some behavior is endued with the virtual human. The motion course of frags and its damage to human are simulated by particle system on the basis of terminal effect and damage theory. Finally, using these returns it designs and realizes the virtual environment in the virtual reality training system of artillery element fire command. |
