Sapphire Plug-ins for Autodesk: ZGlow

ZGlow

Glows areas of the source clip with varying widths depending on the depth values from a ZBuffer input. Separates the input into a number of layers and applies different amounts of glow depending on Width Near, Width Far, Brightness Near, and Brightness Far parameters.

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 .
Brings up the Preset Save dialog to save a preset for this effect.

Brightness: Default: 2, Range: 0 or greater.
Scales the brightness of all the glows.

Brightness Near: Default: 1, Range: 0 or greater.
Scales the glow brightness for near objects.

Brightness Far: Default: 1, Range: 0 or greater.
Scales the glow brightness for far objects.

Layers: Integer,  Default: 5, Range: 2 to 50, Shared .
The number of depth layers to separate the source into. More layers require more processing but give smoother results in Z. More layers are sometimes needed to avoid visible seams between the layers.

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.

Width Near: Default: 0.05, Range: 0 or greater.
The glow width of near (close) objects.

Width Far: Default: 0.5, Range: 0 or greater.
The glow width of far away objects.

Width X: Default: 1, Range: 0 or greater.
Scales the horizontal glow width. Set to 0 for vertical only.

Width Y: Default: 1, Range: 0 or greater.
Scales the vertical glow width. Set to 0 for horizontal only.

Width Red: Default: 1, Range: 0 or greater.
Scales the red glow width. If the red, green, and blue widths are equal, the glows will match the color of the source clip. If they are not equal, the glows will vary in color with distance.

Width Green: Default: 1.2, Range: 0 or greater.
Scales the green glow width.

Width Blue: Default: 1.4, Range: 0 or greater.
Scales the blue glow width.

Color: Default rgb: [1 1 1].
Scales the color of the glow. The colors and brightnesses of the glow are also affected by the Source input.

Threshold: Default: 0.5, Range: 0 or greater.
Glows are generated from locations in the source clip that are brighter than this value. A value of 0.9 causes glows at only the brightest spots. A value of 0 causes glows for every non-black area.

Threshold Add Color: Default rgb: [0 0 0].
This can be used to raise the threshold on a specific color and thereby reduce the glow generated on areas of the source clip containing that color.

Scale Source: Default: 1, Range: 0 to 1.
Scales the brightness of the Source input when combining with the glow. This does not affect the generation of the glow itself.

Z Min: Default: 0, Range: 0 to 1.
Clamps all Z values to this minimum bound. Use this parameter to create a constant glow on all parts of the image nearer than Z Min.

Z Max: Default: 1, Range: 0 to 1.
Clamps all Z values to this maximum bound. Use this parameter to create a constant glow on all parts of the image farther than Z Max.

Params2:

Width Red Near: Default: 1, Range: 0 or greater.
Scales the red glow width for near objects.

Width Green Near: Default: 1, Range: 0 or greater.
Scales the green glow width for near objects.

Width Blue Near: Default: 1, Range: 0 or greater.
Scales the blue glow width for near objects.

Width Red Far: Default: 1, Range: 0 or greater.
Scales the red glow width for far objects.

Width Green Far: Default: 1, Range: 0 or greater.
Scales the green glow width for far objects.

Width Blue Far: Default: 1, Range: 0 or greater.
Scales the blue glow width for far objects.

Color Near: Default rgb: [1 1 1].
Scales the glow color for near objects.

Color Far: Default rgb: [1 1 1].
Scales the glow color for far objects.
