PyCon Canada 2015 - Interactive Media Development with Python & TouchDesigner Projects

Instructions and project files for Interactive Media Development with Python & TouchDesigner tutorial at PyCon Canada 2015

##Final Product

##Goals The goal of this tutorial is to quickly use TouchDesigner and Python to:

1. Get sensor inputs and create control values and triggers
2. Use the sensor triggers to scrape data from Twitter using Python Requests library
3. Analyze the incoming tweets to create a map of most used words in tweets relating to PyCon Canada 2015
4. Visualize the word cloud
5. Use sensor control values to manipulate the word cloud in real-time

##Pre-requisite steps

1. Download 64-bit Windows Python 3.x (3.5 will be used in this tutorial)
2. Run pip install requests requests-oauthlib in an elevated command prompt (make sure your PATH is calling Python 3 pip!)
3. Download and install TouchDesigner
4. In TouchDesigner, in the menu bar, go to Edit -> Preferences.
5. In the General settings, set the Python 64-bit Module Path to your site-packages folder. With Python 3.5, the default is C:/Program Files/Python 3.5/Lib/site-packages
6. Go to Twitter's Developer page and register an application
7. Generate a set of OAuth credentials for yourself
