# Color utilities for LED animations

This package is a collection of some utility functions for working with

color. It is primarily intended for LED animations on microcontrollers using

[TinyGo](https://tinygo.org/), therefore it has been optimized for devices

without FPU.

It is inspired by [FastLED](http://fastled.io/) but does not implement any

drivers for LED strips to keep development focused on fast animations.

## Noise functions

This package contains a number of Simplex noise functions.

[Simplex noise](https://en.wikipedia.org/wiki/Simplex_noise) is very similar

to Perlin noise and produces naturally looking gradients as you might

encounter in nature. It is commonly used as a building block for animations,

especially in procedurally generated games.

Be warned that Simplex noise is

[patented](https://patents.google.com/patent/US6867776) (set to expire on

2022-01-18) so use at your own risk for computer graphics. This patent may or

may not apply to LED animations, I don't know.

## Animation demos

There is a [demos](./demos) subpackage which contains a number of simple

animations that can be directly applied to surfaces implementing the

[`Displayer`](https://godoc.org/github.com/aykevl/ledsgo/demos#Displayer)

interface.

## License

This package is licensed under the MIT license, just like the FastLED library.

See the LICENSE file for details. Some code has been copied from the FastLED

library, this is indicated in the code.
