# 2D-Procedural

Generate 2D gradients, noise, and other patterns programmatically for your material.

## Overview

Use these nodes to generate gradients, noise, and other types of patterns and apply them to textures or other 2D surfaces. For example, you might use a horizontal or vertical ramp node to create a color gradient on a surface.

## Topics

### Nodes

[`Ramp Horizontal`](/documentation/ShaderGraph/2D-Procedural/Ramp-Horizontal)

A left-to-right linear value ramp (gradient) generator.

[`Ramp Vertical`](/documentation/ShaderGraph/2D-Procedural/Ramp-Vertical)

A top-to-bottom linear value ramp (gradient) generator.

[`Ramp 4 Corners`](/documentation/ShaderGraph/2D-Procedural/Ramp-4-Corners)

A four-point linear value ramp (gradient) generator.

[`Split Horizontal`](/documentation/ShaderGraph/2D-Procedural/Split-Horizontal)

A left-to-right split matte, split at a specified U value.

[`Split Vertical`](/documentation/ShaderGraph/2D-Procedural/Split-Vertical)

A top-to-bottom split matte, split at a specified V value.

[`Noise 2D`](/documentation/ShaderGraph/2D-Procedural/Noise-2D)

A 2D Perlin noise generator.

[`Cellular Noise 2D`](/documentation/ShaderGraph/2D-Procedural/Cellular-Noise-2D)

A 2D cellular noise generator.

[`Worley Noise 2D`](/documentation/ShaderGraph/2D-Procedural/Worley-Noise-2D)

A 2D Worley noise generator.
