Modelling and simulation of virtual earth scene

Starting from the earth model, a new method was proposed that the rotation of atmospheric could be divided by monsoon belt. In order to improve the fidelity, the reason caused atmospheric scattering was investigated, and the scattering algorithm was studied and implemented by GPU programming. At the end, the star scene model based on multiple texture blending was given. The result of experiment shows that these methods have not only given a substantial increase in fidelity, but also guaranteed real-time rendering. It can be widely used in simulation of space battlefield and exploration.
