wgsl-noise

This repository contains the noise functions that were converted from GLSL to WGSL, sourced from ashima/webgl-noise and stegu/webgl-noise.

Please note that it currently does not include psrdnoise since the original author has already provided a version converted to WGSL (please refer to: stegu/psrdnoise).

Special thanks to Stefan Gustavson and Ian McEwan, Ashima Arts for their contributions to the community! This repository focuses solely on the language porting.

Be sure to visit ashima/webgl-noise, stegu/webgl-noise, and stegu/psrdnoise for more information!

Finally, a big thank you to Stefan Gustavson for the help!

Usage

All files with the .wgsl extension are located in subdirectories within the src directory.

To install wgsl-noise using npm, you can run:

``bash
npm i wgsl-noise
`

To avoid potential naming conflicts between math functions when using multiple noise functions in the same app, I separate math functions from noise functions by default.

When using this package, you should first import the math and then include the specific noise functions that you need as follows:

`js
import { math, cellular2D, snoise3D, } from "./node_modules/wgsl-noise/dist/main.js"

const shaderCode =
${math}
${cellular2D}
${snoise3D}

// your shader code...

`

If you are certain that you will only use a single noise function, you can import the functions located in the src directory as follows:

`js
import { cellular2D } from "./node_modules/wgsl-noise/src/main.js"

const shaderCode =
${cellular2D}

// your shader code...

`

The default entry point for wgsl-noise is specified in wgsl-noise/package.json:

`js
{
// ...
"main": "dist/main.js",
// ...
}
``
