# Pattern node

The Pattern node outputs a pattern texture generated from common waveform shapes.

## Inputs

The Pattern node does not accept any input.

## Outputs

The Pattern node provides a greyscale texture obtained by mixing a horizontal and a vertical pattern.

Many different patterns can be created using this node, do not hesitate to experiment.

## Parameters

The Pattern node accepts the following parameters:

- the X and Y parameters define the pattern and their number of repetitions that will be propagated along the X axis and Y. The following patterns are available:
  - Sine: the value follows a sinus waveform
  - Triangle: the value follows a triangle waveform (changes linearly from 0 to 1 and from 1 to 0)
  - Square: the value follows a square waveform (stays constant at 0, then 1)
  - Sawtooth: the value follows a sawtooth waveform (changes linearly from 0 to 1, then jumps back to 0)
  - constant: the value is 1
- the Combiner parameter is the function used to combine the X and Y patterns. The available functions are multiply, add, max, min, xor and pow
