This study is an important part of view scene system of automobile driving training simulator. In this paper, the modeling technology for 3D geometrical object and the maneuvers of loading scene objects are analyzed and researched, and the view scene system software for automobile driving training simulator is developed. This software can be learned and used easily. Not only the types of roads and the operations for automobile that required in automobile driving training are included, but also the current running status of automobile is judged and the relative information is displayed.A graph user interface (GUI) with Chinese and the style of Windows is designed. Through this GUI, users can complete the real-time control of the running automobile and the change of view point, and so on. In this paper, the features of the data in the view scene system of automobile driving training simulator are analyzed. According to the features, the Data Base and pointer array are used to organize and manage the scene data. In the modeling of 3D geometrical object, both manual coding and 3D modeling tool are adopted. These ways not only increase the speed of graph's generation, but also reduce the time for software development. Object Modeling Technology (OMT), mipmapping, texture mapping, environment effect disposing etc. are applied to increase the efficiency of scene's generation, and enhance the reliability and the third dimension of simulation. Especially, the features of Object-Oriented (OO) ideal, such as inheritance, encapsulation, polymorphism, are used to realize the expression of all roads and scenes, to cut down the programming codes and to shorten the software development. DirectX 3D graph programming is used to design and display 3D animating graphs, and the vivid degree of three dimensions is realized. Besides, the technology of page-flipping, multi buffering, area display in maneuvering scene object and multi thread are used to make the animation more smooth.
