摘要
The effect of multi-layer atmospheric scattering on the visibility F of each point P on a visible surface of each polygon in a display scene, in a computer image generation (CIG) system, is provided by determining the effective average reciprocal half-fading distance between viewpoint and the viewed point, knowing the altitudes at which each of the different scattering layers start and accounting for any transitional slopes therebetween. The total reduced visibility of that viewed point P is a function of the average reciprocal half-fading distance for that point and of the total range between the viewed point P and the viewpoint VP.
