802 Chapter 11 Working With Generators
Noise
Where would motion graphics artists be without a noise filter or generator? To make
animated noise, you can keyframe the Random Seed parameter in the Noise
Dashboard or Inspector. When filters are applied to an animated Noise generator, you
can create some unique textures. In the second image below, the Scrape distortion
filter is applied to an animated Noise generator to create a vibrant, electric-light type
texture.
Op Art
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.
