Outer Cutoff: Defines an outer stopping area for the generator. The lower the value, the
more the outer edges of the generator are cut off. Objects composited below the generator
in the project appear in the cutoff areas.
HUD Controls
The HUD contains the following controls: Color, Color Variance, Divisions, Sharpness,
Waviness, Frequency, Phase, Inner Cutoff, and Outer Cutoff.
Op Art 1
There are three Op Art generators to help confuse your background-foreground senses.
The Op Art generators create mathematically oriented patterns using a repetition of
simple shapes. Although some static patterns create a visual illusion of movement, you
can keyframe the Op Art parameters to create actual moving moiré patterns.

Parameters in the Inspector
Line Thickness: Sets the thickness of the lines in the pattern.
Color 1: Sets the first color of the pattern. Use the disclosure triangle to display Red,
Green, Blue, and Opacity sliders for more precise color selection.
Color 2: Sets the second color of the pattern. Use the disclosure triangle to display Red,
Green, Blue, and Opacity sliders for more precise color selection.
Contrast: Sets how sharp or blurred the division is between the lines and the background.
Wavelength 1: Sets the frequency of the wave up and down.
Wavelength 2: Sets the frequency of the wave from left to right.
Amplitude: Sets the amplitude of the waves.
Roundness: Sets the shape of the waves.
HUD Controls
The HUD contains the following controls: Line Thickness, Color 1, Color 2, Contrast,
Wavelength 1, Wavelength 2, Amplitude, and Roundness.
