Recursion is a technique that involves the repetition of an element within itself.
Fractals
Fractals are shapes that contain infinite details the further you zoom in.
Mandelbrot Set
Can be generated natively with After Effects or with the "Mandelbot" plugin in Chosen Few FX.
Julia Set
Can be generated natively with After Effects or with the "Mandelbot" plugin in Chosen Few FX.
Sierpinski's Triangle
Menger Sponge
Similar concept to Sierpinski's Triangle but with squares.
Usage
Recursive Recycling
This is the simplest type of recursion to set up. The concept is that you set up an effect, render it, then go back into that effect and replace the footage with that render. Do that as many times as you wish for a cool recursive effect.
Analog Recursion
A type of Analog Distortion, this style of recursive editing involves filming the output while piping that input as the output, live. This is commonly also known as a feedback loop or analog trails and can create effects that range from rainbow trails to fractal patterns.
