WebGL 101 and the making of

  • Apr 4, 2013 · 7:00 PM
  • This location is shown only to members

VISUALIZATION: A live-coding session where you will learn how to use WebGL, starting with a "hello world" challenge to colouring the streets and highways of Toronto in a WebGL-based map. This event is for Data Heads who are looking to learn a new and powerful data visualization tool (which can be challenging to learn on your own). Some background in javascript is very helpful.

Kevin Branigan, our WebGL expert, will kickoff this meetup with a story of how he created Toronto's first TTC trip planner,, and other visualizations of Toronto's transit activity.


Pro-Talk [30 min]: Kevin shares his experience of wrangling TTC data, a task equivalent to herding cats . He has a vision for a better quality of publicly available transit information, from the launch of in 2008 to his current project of mapping the PATH. You'll love his story.

Live Coding Tutorial [90 min]: As a group, we will modify Kevin's sample WebGL project to:

1. Create a "hello world" WebGL page using simple shapes

2. Manipulate a larger dataset of Toronto map data


1. Laptop with a modern web browser - you might consider Chrome

2. A text editor for editing javascript and HTML files


This session is intended for people who are eager to learn a complex visualization tool (WebGL) form someone who understands the challenges and is ready to share what he's learned.


A git project and dataset will be provided at the meetup.

    I just found out I got in but it's too late for me to get back downtown - I will miss this but I must decline

    Really bummed I can't make it despite getting off the waitlist. Would be great if links to repos or resources could be posted after the event for those of unfortunate and eager ones who can't make it!

    This sounds like a really interesting and exciting event, so my request to everyone who's RSVP'd: please do change it if you are unable to attend since this event looks to be gathering quite the wait list!
