卫星与深空动态场景实时仿真系统

卫星与深空动态场景的实时仿真对于航空航天、军事国防等领域有着重要意义。现提出了一个深空动态场景的绘制方法，该方法综合了计算机图形学和天文学的知识，建立了基于天文学星表的深空场景模型，计算出卫星及各星体的运行轨迹，实现了卫星目标和深空场景的真实感合成，并采用一系列加速绘制技术，最终实现了深宅动态场景的实时生成和交互式虚拟漫游。

Real-time Simulation System of Satellite and Outer Space Scene

Real-time simulation of satellite and outer space scene had been iound 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 modelled 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 satelites and outer space btckground was achieved. Finally by adapting the accelerated rendering techniques of scene, real-time dynamic outer space scene and interactive virtual walkthrough are successfully realized.
