| Abstract: | After making an overview of the atmosphere model,and introducing the 3d rendering methods for the effect of atmosphere,a fast algorithm based on simplified atmosphere model is given.This algorithm uses billboard and the effect of fog,and simulates the effect of Earth's atmosphere vividly.The experiment results show that this method is simply and efficiency,and avoids complicated physical computing. |
