Abstract: | This paper proposes a new method to generate the dynamic infrared outer space scene in real time. In the paper, we first model
the dynamic infrared background of star sky based on the infrared star catalogue and temporal and spacial coordinate transformations.
We also present a new concept called infrared star magnitude for given infrared receiving wavebands to display the infrared
star sky effectively. Then we put forward an infrared image synthesis model for outer space targets based on the method of
divided elements and energy equilibrium. To generate the dynamic infrared outer space scene, several simplification and accelerating
techniques such as Billboard, Levels of Details and Occlusion Culling are hired to accelerate the generating speed of the
scene. Finally infrared images of targets, background of outer space scene at different infrared receiving wavebands are drawn
and the dynamic infrared outer space scene is successfully carried out in real time.
