Flight Simulator Virtual Visualization Technology

Information visualization has become a development trend of application with the development of computer, communication, and the corresponding technologies. Virtual visualization of flight simulation has been hot topic with time going, which is widely used and very important in aircraft design, performance analysis, pilot training, battle analysis and the national defenses. The terrain creation of large area, visualization modeling and dynamical driving of instrument, visualization design of scene and the flutter problem of scene are emphases in the research of virtual visualization of flight simulation.Some kinds of modeling technologies of visualizations and methods of optimization are introduced. The modeling tool of Creator has been used to model the airplane, instruments and the large area terrains. The technology of LOD has been adopted to realize the large area terrain visualization model, dynamical mutual of pointers of instruments have been carried out with DOF, and technology of the Bounding Volumes and the format of FST have used to improve the feedback velocity of real time of the model controls.The actual environment sounds are added in the design of visual visualization environment to tone up the actual feeling, and the mutual driving of real time dynamic state of instrument in the seating accommodation are realized with the visualization program of LynX and the code programming. The automotive cruise of virtual scene can be realized with the two kinds of inspect control and swift ways of interface operations for graphics user and the keyboard operations. The design of collision checking makes it much more realistic for the virtual visualization system of flight simulation.The reasons of flutters are analyzed particularly in the research of scene flutters at many aspects including net structure, coordinate shift and the hardware station of computer. The applied treatments including data smoothing treatment, station...
