Study On The Key Technology Of The Three-Dimensional Simulation System To The Flying Object

With the development of computer technology and Scene Simulation Technology, we welcome the coming of the Virtual Reality Times. Based on the Visual Simulation Technology to simulate the war field environment, people could not only minify the expense of exercises and rehearses but also shorten the tactics prepared time, consequently to obviously improve the quality of the exercises and rehearses and increase the battle effectiveness. Open Graphics Library, independence of the hardware and window system, is a kind of 3D computer graphics and model base .It could be used in any computer, which uses any, operate system and it works in the Client/Server mode. It is a normal graphics base in the application fields of the professional graphics disposal and science calculation, etc. The essay argues that how to use Computer Visual Simulation Technology and 3D development software: OpenGL and VC6.0 to setup a 3D Aviation Scene Simulation System in order to simulate a process of one flying machine aviating in some special terrain. The flying machine could be observed and controlled by the keyboard, just like pitching, deflection, acceleration, etc. It concludes the input of 3D entity model, the simulation of 3D terrain, the draft of sunshine and sky, the draft of flying machine and flame and the aviation dynamics simulation. On the basis of completing the aviation simulation, it could be extended to develop other training simulation software.
