Sapphire Plug-ins for Autodesk: ZFogLinear

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:

Load Preset: Push-button .
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset: Push-button .

Fog Near: Default: 0, Range: 0 to 1.

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.
