Terrain - Fog

Fog is an effect created in a terrain window by applying a color to an increasing amount to points located at an increasing distance from the viewer. The visual result is very similar to that of real haze or fog, which has a greater effect on distant points because they are seen through more haze. The Terrain - Fog dialog provides options to control the appearance of fog in the terrain window. Applying fog to a terrain enhances the sense of 3D realism.

Default fog. A slight amount of fog applied to a terrain enhances reality by providing haze in the distance.

We can increase the fog by increasing the nearer number in the Render fog from parameter. This provides a hazier landscape.

Changing the color of fog changes the color of the sky as well, since sky is just fog color piled up to an infinite distance. Color shown is a dark gray color. Using black and a slight amount of fog creates night effects.
