Three Dimensional Graphics Technology Of Computer Graphics In The Application Of Aircraft Reai-Time Display

Computer graphics is one of the most young and active discipline of computer science, it is also a cross subject of strong, not only have close connection with mathematics, optics, structure design and other non computer science disciplines, but also have close connection with digital image processing, computational geometry, pattern recognition and other secondary computer science disciplines.The three-dimensional graphics is the main part of computer graphics research, which involves several major technology with view frustum culling,3D blanking and anti aliasing. Although the technology has been the existence of multiple algorithms, but these are not efficient computation algorithms such as the scanning lines and the depth buffer algorithm dimensional blanking technique is highly complex calculation time, without the aid of hardware acceleration will not be used. Despite the current computer graphics has been able to meet most of the demand, but is far from perfect, relative to its theory basis, algorithm and hardware operation efficiency become the short board. In this paper, three-dimensional graphics technology, as several major vertebral cutting, blanking and three-dimensional anti-aliasing have made some improvements, improved its operational efficiency.Four rotor aircraft because of its small size, flexible movement and other characteristics, are widely used in many applications, such as aerial photography, monitoring and so on. Meanwhile, the smaller size and greater amount of input control also contributed to this aircraft is difficult to control, often engineers in the development process needs to be many times the aircraft flight, real-time observation of its position and posture, and then adjust the parameters. As the aircraft flying at high altitude is generally not conducive to observe the state, and four-rotor small, it is difficult in a hundred meters to accurately observe their posture with the naked eye. To solve these problems, this paper combined with computer graphics technology, designed for aircraft flight status of a real-time analog display graphics software.
