摘要 渲染真实的地球环境可以提高视景仿真系统的逼真度,增强航天员训练时的沉浸感。为了提高视景显示的真实感和实时性,研究基于可编程图形硬件GPU仿真地球大气散射现象的方法,探讨了大气散射模型,并基于GPU的可编程性给出了实现方法和过程。结果表明该方法提高了实时渲染效率,增强了视景仿真系统的真实感。 Rending the real earth environment is helpful to increase the reality of vision simulation system,so it can boost the astronauts’ immersion feeling during their training.The method to simulate atmospheric scattering on the earth was studied based on GPU,and the model of atmospheric scattering was discussed,finally the realization was given.The result shows that the method could improve rending efficiency and the reality of vision simulation system.
