A number of methods have been developed for creating reali tic images of natural scenes. Their applications include flight simulator ,the visual as essment of outdoor scenery, etc. Previously, many of these methods have focused on creating images under clear or lightly cloudy days. Simulations under bad weather conditions, however, are one of the important issues for realism. Lightning is one of the esential element for these types of simulations. This paper propose an efficient method for creating realistic image of scenes including lightning. Our method can create photo-realistic images by taking into account the scattering effect due to clouds and atmospheric particles illuminated by lightning. Moreover, graphics hardware is utilized to accelerate the image generation. The usefulnes of our method is demonstrated by creating images of outdoor scenes that include lightning.
