Fractal

This fractal node takes a list of Vectors and outputs a list of equal length containing Floats in the range 0.0 to 1.0.

Inputs & Parameters

Parameters	Description
Noise Function	The node output only Scalar values
Noise Type	Pick between several noise types Blender Cell Noise New Perlin Standard Perlin Voronoi Crackle Voronoi F1 Voronoi F2 Voronoi F2F1 Voronoi F3 Voronoi F4 See mathutils.noise docs ( Noise )
Fractal Type	Pick between several fractal types Fractal MultiFractal Hetero terrain Ridged multi fractal Hybrid multi fractal
H_factor	Accepts float values, they are hashed into Integers internally.
Lacunarity	Accepts float values
Octaves	Accepts integers values
Offset	Accepts float values
Gain	Accepts float values

Examples

Basic example with a Vector rewire node.

Notes

This documentation doesn’t do the full world of fractals any justice, feel free to send us layouts that you’ve made which rely on this node.

A very interesting resource is “the book of shaders”, it’s about shader programming but there is a very useful fractal paragraph:
