TextureChromaSpiralIn the S_Textures Plugin.Creates an abstract texture by applying a WarpChroma effect to a procedurally generated noise texture. Inputs:
|
|
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.
-
Noise Frequency:
Default:
6,
Range:
0 or greater.
The spatial frequency of the initial noise texture. Increase to zoom out, decrease to zoom in.
-
Noise Octaves:
Integer, Default:
3,
Range:
1 to 10.
The number of summed layers of noise. Each octave is twice the frequency and half the amplitude of the previous. A single octave gives a smooth texture. Adding octaves makes the result approach a fractal (1/f) noise texture.
-
Noise Shift:
X & Y, Default:
[0 0],
Range:
0 or greater.
Translation offset of the initial noise texture.
-
Noise Seed:
Default:
0.23,
Range:
0 or greater.
Used to initialize the random number generator. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.
-
Center:
X & Y, Default:
[0 0],
Range:
any.
The center location of the chroma warp, in screen coordinates relative to the center of the frame. This parameter can be adjusted using the Center Widget.
-
Z Dist:
Default:
0.7,
Range:
any.
The distance that the chroma warp effect is applied over.
-
Rotate:
Default:
-8,
Range:
any.
The rotation of the spiral, in degrees. Set to 0 for a straight zoom.
-
Brightness:
Default:
1,
Range:
0 or greater.
Scales the brightness of the result.
-
Color:
Default rgb:
[1 1 1].
Scales the color of the result. For example, if it is yellow [1 1 0], the blue of the result will be 0.
-
Steps:
Integer, Default:
12,
Range:
3 to 100.
The number of color samples along the spectrum to include. More steps give a smoother result, but require more time to process.
-
Offset:
Default:
0,
Range:
any.
Adds this gray value to the result (or subtracts if negative). 0 has no effect, .5 is middle gray, and 1 is white.
-
Wrap:
Popup menu, Default: Reflect
.
Determines the method for accessing outside the borders of the source image.
-
No:
gives black beyond the borders.
- Tile: repeats a copy of the image.
- Reflect: repeats a mirrored copy. Edges are often less visible with this method.
- Tile: repeats a copy of the image.
-
No:
gives black beyond the borders.

Params3:
-
Mocha:
Default:
0,
Range:
0 or greater,
Shared
.
Brings up the Mocha window for tracking footage and generating masks.
-
Blur Mocha:
Default:
0,
Range:
0 or greater,
Shared
.
Blurs the Mocha Mask by this amount before using. This can be used to soften the edges or quantization artifacts of the mask, and smooth out the time displacements.
-
Mocha Opacity:
Default:
1,
Range:
0 to 1,
Shared
.
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.
-
Invert Mocha:
Check-box, Default:
off,
Shared
.
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.
-
Show Mocha Only:
Check-box, Default:
off,
Shared
.
Bypass the effect and show the Mocha Mask itself.
-
Bypass Mocha:
Check-box, Default:
off,
Shared
.
Ignore the Mocha Mask and apply the effect to the entire source clip.
