S_TextureCells

Generates an image of procedural cellular shapes. The Rotate Speed parameter causes the cell centers to rotate within each cell 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: 16,  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.

Seed:   Default: 0.234,  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.

Rotate Centers:   Default: 0,  Range: any.
Rotation offset of the cell centers, in counter-clockwise degrees.

Rotate Speed:   Default: 90,  Range: any.
The speed of cell center rotation, in counter-clockwise degrees per second. If non-zero, the cell centers are automatically animated to wiggle at this rate.

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.

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

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.
