The X-type Truck Training Simulator 3d Scene Generation Technology Research

With the degree of The Chinese People's Liberation Army's armoring and mechanization is becoming higher and higher, Chinese army of ensure engineering has been equipped with large amount of caterpillar X all-purpose mobile machinery shop. Consequently, a method, which can simulate the operation truly , is needed urgently by the engingneer army. By this method, the driver can be trained fully and the real equipment can remain intact to economize the training fee.Thus came forth the simulant system of the training of driving and operating x mobile machinery shop. In this system, the software of three-dimensional prospect can direct affect the real time simulant degree and the reality of simulation.The technology of creating the three-dimensional prospect which this paper deals with, is not only hard but also important in the whole project. 3DSMAX and Photoshop were used firstly to construct the model of the outer materials of the mobile machinery shop. Then by using Visual C++ and DirectX and two modeling methods——the program imaging modeling and the hard coding modeling, we finish modeling of the bodywork of the chop, also the dynamic modeling of three operation: the shovel changing, overturn and controling depth of pushing soil part in the process of pushing soil by using the theory of trigonometric function and switch of dimensional matrix. In the process of simulating the edaphic movement under the view of first person the concept of the system of particle was used for the first time. All the means facilitate the form of good vision.
