This paper presents a method of computing snow accumulation as a per pixel effect while rendering the scene. The method is similar to the shadow mapping method for shadow calculations. A depth buffer is used to find out how much snow a particular surface should receive. The amount of snow is then modified depending on the slope of the surface. To render the snow in a convincing way 3D noise is utilized for the lighting of the snow surface.
