# FastNoise Lite
[Web Preview App](https://auburn.github.io/FastNoiseLite)
FastNoise Lite is an extremely portable open source noise generation library with a large selection of noise algorithms. This library focuses on high performance while avoiding platform/language specific features, allowing for easy ports to as many possible languages.
This project is an evolution of the [original FastNoise](https://github.com/Auburn/FastNoiseLite/tree/FastNoise-Legacy) library and shares the same goal: An easy to use library that can quickly be integrated into a project and provides performant modern noise generation. See a breakdown of changes from the transition to FastNoise Lite [here](https://github.com/Auburn/FastNoiseLite/pull/49)
If you are looking for a more extensive noise generation library consider using [FastNoise2](https://github.com/Auburn/FastNoise2). It provides large performance gains thanks to SIMD and uses a node graph structure to allow complex noise configurations with lots of flexibility.
## Features
- 2D & 3D sampling
- OpenSimplex2 noise
- OpenSimplex2S noise
- Cellular (Voronoi) noise
- Perlin noise
- Value noise
- Value Cubic noise
- OpenSimplex2-based domain warp
- Basic Grid Gradient domain warp
- Multiple fractal options for all of the above
- Supports floats and/or doubles
### Supported Languages

### [Documentation](https://github.com/Auburn/FastNoiseLite/wiki/Documentation)
## FastNoise Lite Web Preview App
Link: [https://auburn.github.io/FastNoiseLite](https://auburn.github.io/FastNoiseLite)
A compact testing application is available for testing all features included in FastNoise Lite with a visual representation. This can be used for development purposes, testing noise settings and generating noise textures for export.
Source code can be found in the [WebPreviewApp](/WebPreviewApp/) directory.
