Real-time simulation system of satellite and outer space scene

Real-time simulation of satellite and outer space scene had been found great application in aviation and spaceflight, military affairs and national defence. In this paper, a new method to render dynamic outer space scene was proposed. By integrating the knowledge of Computer Graphics and Astronomy, we first modeled the scene of outer space based on astronomical star catalogue. Then we calculated the tracks of satellites, stars and planets. And the realistic synthesis between satellites and outer space background was achieved. Finally by adapting the accelerated rendering techniques of scene, real-time dynamic outer space scene and interactive virtual walkthrough are successfully realized.
