S_TextureNeurons Creates an abstract texture resembling moving nerve cell tendrils. The Phase Speed and Morph Speed parameters cause 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.

Arms:   Integer,  Default: 9,  Range: 0 to 50.
The number of tendrils emanating from each center point in the texture.

Softness:   Default: 0.5,  Range: 0.01 or greater.
Decrease for sharper line edges. Increase for smoother line edges or to reduce aliasing.

Thickness:   Default: 1.1,  Range: 0 or greater.
Decrease for thinner lines. Increase for stronger brighter lines.

Outer Bright:   Default: 0.4,  Range: 0.01 to 1.
Scales the brightness of the regions away from the neuron centers. Decrease to remove the connecting lines and leave only the star shapes at the centers.

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.

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.

Phase Start:   Default: 0,  Range: any.
Amount to rotate the arms about their centers.

Phase Speed:   Default: 0.05,  Range: any.
Speed to automatically rotate the arms and move the lines over time.

Morph Speed:   Default: 0.05,  Range: any.
Speed to automatically undulate the underlying noise pattern over time.

Morph:   X & Y,   Default: [1 0],  Range: any.
The horizontal and vertical directions to undulate the underlying noise pattern, when using Morph Speed.

Twist:   Default: 0,  Range: any.
Amount to rotate the centers to cause a twisting effect.

Wiggle Amp:   Default: 0.1,  Range: 0 or greater.
Amount of additional noise too apply along the pattern of lines. Turn down to get smoother lines.

Wiggle Freq Rel:   Default: 2,  Range: 0 or greater.
Frequency of the additional noise.

Wiggle Octaves:   Integer,  Default: 4,  Range: 1 to 10.
The number of octaves to use for the additional noise.

Smooth:   Default: 0,  Range: 0 or greater.
Amount to blur the line pattern. Increase for a defocus look, or to help remove aliasing artifacts.

Brightness:   Default: 1,  Range: 0 or greater.
Brightness of the result.

Color:   Default rgb: [1 1 1].
Scales the color of the result.

Glow Brightness:   Default: 2,  Range: 0 or greater.
Brightness of the glow applied to the texture.

Glow Color:   Default rgb: [1 0.8 0.8].
Color of the glow applied to the texture.

Glow Width:   Default: 1,  Range: 0 or greater.
The width of the glow applied to the texture.

Glow Width Red:   Default: 0.4,  Range: 0 or greater.
The relative red width of the glow.

Glow Width Grn:   Default: 0.6,  Range: 0 or greater.
The relative green width of the glow.

Glow Width Blue:   Default: 0.8,  Range: 0 or greater.
The relative blue width of the glow.

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.
