ZFogLinear In the S_ZFog Plugin. Mixes a fog color into the source clip using depth values from a ZBuffer input. The fog amount varies linearly between Fog Near and Fog Far depending on the depth. Inputs: Source:  The clip to be processed. ZBuffer:  The input clip containing depth values for each Source pixel. These values should be in the range of black to white, and it is best if not anti-aliased. Normally black corresponds to the farthest objects and white to the nearest, though this can be adjusted using Z Buffer parameter.

Parameters:

Fog Near:   Default: 0,  Range: 0 to 1.
The amount of fog to add to nearby (close) objects.

Fog Far:   Default: 0.8,  Range: 0 to 1.
The amount of fog to add to far away objects.

Z Buffer:   Popup menu,  Default: White is Near.
How to interpret the values in the Z buffer.

Black is Near:  Black pixels in the Z buffer indicate that the object at that point is near (close to you), and white means far away.

White is Near:  White pixels in the Z buffer indicate that the object at that point is near (close to you), and black means far away.

Fog Color:   Default rgb: [0.5 0.5 0.5].
The fog color should normally match the sky or background color of the source clip. Use gray for mist, brown for smog, blue for underwater, etc.
