Abstract: Training with simulation is an important method in mordern military training. In this paper the characteristics and the alteration pattern of the view field of the tank's telescope are analyzed in order to improve the visual effects of the tank fire simulator. The corresponding display mathematical model is also put forward. On the basis of this model, a quick texture mapping algorithm which can generate the view of ground in real time on personal computer is presented, thus the visual effects of firing while tank is runing can be simulated realistically.
