TextureCausticsComp In the S_TexturesComp Plugin. Simulates the patterns created when light rays are reflected or refracted by a curved surface. Caustics can often be seen at the bottom of a swimming pool in bright sunlight or on objects viewed underwater. Inputs: Back: The clip to use as background.

Parameters:

Load Preset: Push-button .
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset: Push-button .
Brings up the Preset Save dialog to save a preset for this effect.

Ray Focus: Default: 15, Range: 0 or greater.
Alter this to bring the caustic pattern into focus.

Ray Blur: Default: 0.01, Range: 0 or greater.
Softens the caustic pattern.

Ray Density: Integer,  Default: 2, Range: 1 or greater.
Increasing this value will increase the quality of the caustic pattern.

Frequency: Default: 3, Range: 0 or greater.
The frequency of the cautic pattern. Increase for more and smaller elements, or decrease for fewer and larger.

Shift: X & Y,   Default: [0 0], Range: any.
Translation of the caustic pattern. This parameter can be adjusted using the Shift Widget.

Complexity: Default: 2.5, Range: 0 or greater.
The complexity of the caustic pattern. Increase for more high frequency companents within the casutic pattern

Speed: Default: 1, Range: 0 or greater.
Animation speed of the cuastic pattern.

Seed: Default: 0.123, 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.

Brightness1: Default: 0.5, 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 0.05 1].
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.

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

Texture Only: gives only the caustic texture 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.

Scale Back: Default: 1, Range: any, Shared .
Scales the brightness of the background before combining with the textures. If 0, the result will contain only the texture image over black.

Params2:

Params3:

Mocha: Default: 0, Range: 0 or greater, Shared .
Brings up the Mocha window for tracking footage and generating masks.

Blur Mocha: Default: 0, Range: 0 or greater, Shared .
Blurs the Mocha Mask by this amount before using. This can be used to soften the edges or quantization artifacts of the mask, and smooth out the time displacements.

Mocha Opacity: Default: 1, Range: 0 to 1, Shared .
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

Invert Mocha: Check-box,  Default: off, Shared .
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.

Show Mocha Only: Check-box,  Default: off, Shared .
Bypass the effect and show the Mocha Mask itself.

Bypass Mocha: Check-box,  Default: off, Shared .
Ignore the Mocha Mask and apply the effect to the entire source clip.
