TextureChromaSpiral In the S_Textures Plugin. Creates an abstract texture by applying a WarpChroma effect to a procedurally generated noise texture. Inputs: None

Parameters:

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.
