S_TextureLoops Creates an abstract texture of overlapping loop shapes. Three sets of shapes can be separately adjusted, colored, and then combined together. The Phase Speed parameter causes the pattern to automatically change over time. In the Sapphire Render effects submenu. Inputs: Background:  Optional.   The clip to combine the texture image with. This may be ignored if the Combine option is set to Texture Only.

Parameters:

Frequency:   Default: 3,  Range: 0.01 or greater.
The spatial frequency of the texture. Increase to zoom out, decrease to zoom in.

Frequency Rel X:   Default: 1,  Range: 0.01 or greater.
The relative horizontal frequency of the texture. Increase to stretch it vertically or decrease to stretch it horizontally.

Loop Freq:   Default: 4,  Range: 1 or greater.
Frequency of the loops within the noise patterns. Increase for more concentric loops, decrease for fewer.

Phase Start:   Default: 0,  Range: any.
The phase of the ring loops. Shifts inwards or outwards.

Phase Speed:   Default: 0.1,  Range: any.
The automatic change in phase over time.

Seed:   Default: 1,  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.

Thickness:   Default: 0.1,  Range: -1 to 2.
Controls the thickness of the loops.

Softness:   Default: 0.2,  Range: 0.01 or greater.
The softness of the edges of the loop shapes. Increase for smoother edges or to reduce aliasing.

Smooth:   Default: 0,  Range: 0 or greater.
Amount to blur the loop shapes before combining. Increase for a defocus look, or to help remove aliasing artifacts.

Shift:   X & Y,   Default: [0 0],  Range: any.
Translation offset of the texture. Since the texture is procedurally generated it can be shifted with no repeating units or seams occurring. This parameter can be adjusted using the Shift Widget.

Brightness1:   Default: 1,  Range: 0 or greater.
Scales the brightness of Color1. Increase for more contrast.

Color1:   Default rgb: [1 1 1].
The color of the 'brighter' parts of the texture. The colors of the result are determined by an interpolation between Color0 and Color1.

Color0:   Default rgb: [0 0 0].
The color of the 'darker' parts of the texture.

Offset0:   Default: 0,  Range: any.
Adds this value to color0. Decrease to a negative value for more contrast.

Saturation:   Default: 1,  Range: -2 to 8.
Scales the color saturation. Increase for more intense colors. Set to 0 for monochrome.

Loops1 Freq:   Default: 1,  Range: 0.01 or greater.
Relative frequency of the first set of loops.

Loops2 Freq:   Default: 1,  Range: 0.01 or greater.
Relative frequency of the second set of loops.

Loops3 Freq:   Default: 1,  Range: 0.01 or greater.
Relative frequency of the third set of loops.

Loops1 Thick:   Default: 0,  Range: -1 to 1.
Adds this amount to the thickness of the first set of loops.

Loops2 Thick:   Default: 0,  Range: -1 to 1.
Adds this amount to the thickness of the second set of loops.

Loops3 Thick:   Default: 0,  Range: -1 to 1.
Adds this amount to the thickness of the third set of loops.

Loops1 Bright:   Default: 1,  Range: 0 or greater.
Scales the brightness of the first set of loops. Set to zero to remove them.

Loops2 Bright:   Default: 1,  Range: 0 or greater.
Scales the brightness of the second set of loops. Set to zero to remove them.

Loops3 Bright:   Default: 1,  Range: 0 or greater.
Scales the brightness of the third set of loops. Set to zero to remove them.

Loops1 Color:   Default rgb: [1 1 1].
Color of the first set of loops.

Loops2 Color:   Default rgb: [1 1 1].
Color of the second set of loops.

Loops3 Color:   Default rgb: [1 1 1].
Color of the third set of loops.

Invert:   Check-box,  Default: off.
If enabled, the resulting texture colors are inverted. This is similar to swapping Color0 and Color1.

Combine Loops:   Popup menu,  Default: Diff.
Operation used to combine the colors of the three sets of loops.

Add:  adds them together.

Screen:  uses a screen transfer mode to combine them.

Diff:  uses a difference operator to combine them.

Comp:  composites the second over the third, and the first over that.

Bg Brightness:   Default: 1,  Range: 0 or greater.
The background brightness is scaled by this value before being combined with the texture.

Combine:   Popup menu,  Default: Screen.
Determines how the texture is combined with the Background.

Texture Only:  gives only the texture image with no Background.

Mult:  the texture is multiplied by the Background.

Add:  the texture is added to the Background.

Screen:  the texture is blended with the Background using a screen operation.

Difference:  the result is the difference between the texture and Background.

Overlay:  the texture is combined with the Background using an overlay function.

Show Shift: Check-box, Default: on.
Turns on or off the screen user interface for adjusting the Shift parameter.
