In this session, I will talk about WebGL and how to use it for creative coding. I will cover how WebGL works and provide a live coding session where I demonstrate how to create realtime interactive digital arts in your browser. This includes initialization of WebGL in JavaScript as well as an introduction to GLSL shader language. Further resources show you how to process user media like the webcam. This talk is not specific to any WebGL framework, but my material will also contain templates using popular WebGL libraries like THREE.js or PIXI.js.
