# Hello WebGL World!

[![Build Status](https://travis-ci.org/terabaud/hello-webgl.svg?branch=master)](https://travis-ci.org/terabaud/hello-webgl)

This [repository](https://github.com/terabaud/hello-webgl/) features my experiments with WebGL. 

Most demos are using [GLea](lib/glea/), a minimalistic WebGL library written by myself.

 * [Live Demos](https://terabaud.github.io/hello-webgl/)

 * [Slides of my talk about WebGL](https://terabaud.github.io/hello-webgl/talk-webgl/)

# Running it locally

Type `npm install` and `npm start` to start a local development server. 

Currently, there is no transpiling/bundling toolchain like Webpack and Babel/TypeScript.

It's just node [express](https://expressjs.com) serving static files. As other out-of-the-box web servers require some additional configuration, I made a simple server.js on my own. 

# Older Demos

The older demos use an esoteric coding style library I wrote in the 2015s. It provides helper functions for compiling shaders and matrix/vector maths. The code itself of the library is hard to read, but the examples may be useful. Most of the examples just draw a square to the fullscreen and let the fragment shader do its work.
