Description:

Live-Coding is a growing field of performance in Europe and North America. In both continents the primary focus of live-coding is audio. This tutorial will be an introduction/crash course into using OpenGL Fragment Shaders for live-coding graphics. We will be using a toolkit designed around WebGL and run in Google Chrome. The contents of the tutorial will be: a brief explanation of the tool, how it’s constructed, and how it works; a brief explanation of which parts of OpenGL will be used, how it works, and some basic functionalities; some simple hands-on coding examples; finally, adding in an audio source with some hands-on examples for some live-coding experience. Any programming experience is helpful but not necessary.
