Hydra Book
========
Important Notes
--------
Currently I'm editing the book on [hydra-book.glitch.me](https://hydra-book.glitch.me/) so if you are looking at [hydra-book.naotohieda.com](https://hydra-book.naotohieda.com), the content may be a bit old. Also I found strange issues specifically on ubuntu + firefox like sidebar doesn't load, so please try opening on Chrome if you find any issues (if it doesn't fix, please open an [issue](https://github.com/micuat/hydra-book/issues)).
Preface
--------
Hydra is an analog-synth-like coding environment for real-time visuals. It is created by Olivia Jack and is [open-source](https://github.com/ojack/hydra). You can simply open [Hydra editor](https://hydra.ojack.xyz) to start coding. There are a few resources besides this book:
* [The official documentation](https://github.com/ojack/hydra#Getting-Started) is a good resource to get started,
* [Hydra Functions](https://ojack.xyz/hydra-functions/) is an interactive webpage to see functions and its usages,
* [Function list](https://github.com/ojack/hydra/blob/master/docs/funcs.md) covers all the functions available in Hydra,
* and [Hydra Patterns on Twitter](https://twitter.com/hydra_patterns) is a way to get inspirations from other artists.
This article is a work-in-progress online book to collect Hydra snippets. Thanks to its live-coding nature, simply improvising by chaining different functions may lead to an unexpected pattern; nevertheless, studying Hydra in a rather systematic way can reveal its potential. Thus, the goal is not only to accumulate frequently-used techniques to make coding easier but also to research the theory of Hydra to discover new images.
### How to Read
If you are new to Hydra, I recommend you to skim through the book and find patterns you like, and try the code by pressing "open in editor" link. You can change some parameters and press `ctrl+shift+enter` to refresh the sketch.
If you are already familiar with Hydra, I hope reading this book gives you some insight not only about "how" to make a pattern but also "why" a pattern emerges.
