S_TextureSpots

Creates a field of spots that can be distorted and animated. The Warp Speed parameter causes the spots to be distorted over time by a random warping pattern.

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

Radius:   Default: 1,  Range: 0 to 2.
The radius of the spots. Adjust this to change the size of the spots without changing the number of spots.

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.

Rand Warp Amp:   Default: 0.2,  Range: 0 or greater.
The amplitude of a bubble warping distortion applied to the spots.

Rand Warp Freq:   Default: 1,  Range: 0.01 or greater.
The spatial frequency of the noise used for the warping distortion. This has no effect unless Rand Warp Amp is positive.

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.

Warp Start:   X & Y,   Default: [0 0],  Range: any.
The translation offset warping pattern. This has no effect unless Rand Warp Amp is positive.

Warp Speed:   X & Y,   Default: [0.5 0],  Range: any.
The translation speed of the warping pattern. If non-zero the spots are animated to wiggle at this rate. This has no effect unless Rand Warp Amp is positive.

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.
