A simple two-color gradient is used to color the noise map. The noise function will smoothly transition from the first color into the second.
The Advanced Gradient control in Fusion is used to provide more control over the color gradient used with the noise map.
Common Controls
The Image and Settings tabs in the Inspector are duplicated in many Generator nodes. These common controls are described in detail at the end of this chapter in “The Common Controls” section.

The Mandelbrot node
Mandelbrot Node Introduction
This node creates an image pattern based on the Mandelbrot fractal theory set.
Inputs
The one input on the Mandelbrot node is for an effect mask to limit the area where the fractal noise is applied.
— Effect Mask: The optional blue effect mask input accepts a mask shape created by polylines, basic primitive shapes, paint strokes, or bitmaps from other tools. Connecting a mask to this input limits the fractals to only those pixels within the mask.
Basic Node Setup
The Mandelbrot node generates images that can be used for motion graphics and sci-fi effects. Below, it is used to generate motion graphics for the background of a title.

Noise Tab
The Noise tab controls the shape and pattern of the noise for the Mandelbrot node.
This chooses the image’s horizontal and vertical position or seed point.
Zoom magnifies the pattern in or out. Every magnification is recalculated so that there is no practical limit to the zoom.
Defines a point where the calculation of the iteration is aborted. Low values lead to blurry halos.
This determines the repetitiveness of the set. When animated, it simulates a growing of the set.
This rotates the pattern. Every new angle requires recalculation of the image.
