This repository contains the code used in the WebGL tutorial series, organized by video.
Watch the video playlist on Youtube.
These tutorials require using a basic HTTP web server since they load resources via Fetch API (AJAX). There are many options. The first ten tutorials each have a NodeJS Express server in the project folder, but any server may be used.
My recommendation:
python -m http.server 8000
No installation needed, provided Python 3.x is already installed
Or, for Python 2: python2 -m SimpleHTTPServer 8000
