# 3D-Procedural

Generate 3D noise patterns programmatically for your material.

## Overview

3D Procedural nodes generate noise patterns that don’t repeat along the z-axis of your model. Use the nodes to add random variations to parts of your material, such as its surface roughness. Each node produces a different type of noise pattern based on a specific algorithm.

## Topics

### Nodes

[`Noise 3D`](/documentation/ShaderGraph/3D-Procedural/Noise-3D)

A 3D Perlin noise generator.

[`Fractal Noise 3D`](/documentation/ShaderGraph/3D-Procedural/Fractal-Noise-3D)

Zero-centered 3D fractal noise created by summing several octaves of 3D Perlin noise.

[`Cellular Noise 3D`](/documentation/ShaderGraph/3D-Procedural/Cellular-Noise-3D)

A 3D cellular noise generator.

[`Worley Noise 3D`](/documentation/ShaderGraph/3D-Procedural/Worley-Noise-3D)

A 3D Worley noise generator.
