Cloud Simulation In Visual Display System Of Flight Simulator

Flight simulator (FS) is a typical human-in-the-loop simulation system and an important device for simulating the flight's flying by the ground device. So as an effective method for flight training, it has been widely used in today's international aviation field. And the Visual Display System which is used to simulate the scene outside of the cockpit is an important component of the FS. It can provide 70% useful information for the pilot. So it can influence the fidelity and variety of flight training, and is one of the important criterions for estimating whether a FS is advanced.For improving the development level of the native FS, and pushing our country's aviation, the CAAC decide the research direction of developing the simulator, and entrust the Harbin Institute of Technology together with Civil Aviation University of China to complete it. This paper is a part of this research direction. Some techniques related with the cloud system of the Visual Display System in FS have been studied here. Also this paper researches some methods to complete the system and give a primary project.This paper lays heavy emphasis on the development for the software system in the cloud system. This paper has done the requirement analysis of the Visual Display System, and makes clear the function request as well as performance request for the system .At last this paper makes sure the plan and development processes of the cloud system.We used Particle system to create 3D clouds images,and then developed the program in the environment of VC++ and OpenGL(Open Graphics Library).We used texture mapping technique to increase the reality of the cloud model. Then we created the lighting model of the cloud, with the Billboard and Impostor techniques to maintain the immersion and real-time characteristic of the system.In a word, this paper gives a primary study of the method to realize the Cloud System of the Visual Display System in FS. So it lays the foundation for a further development. In addition, this paper involves the whole development process of the Cloud System and some concrete technology problems, so it also...
