Some of our most popular programs are now available over on the website: https://www.programmingforpeople.com/shop In this episode we are exploring the wonderful world of speech. Using a python program to sit behind a OSC control system built in another environment (you can using anything for this – we use touch designer) we explore how to […]

Hey all – taking a stab at something new here – video tutorials on TouchDesigner. I’m starting off with a pretty unusual but not too complicated scenario where we take a python library found on github, that’s not included with touch and embed / transfer it over to DAT’s in the actual file. The upside […]

Additional Files – https://github.com/ancillarymagnet/axidrawings This workshop will focus on the basics of using TouchDesigner’s Script SOP to create geometry programmatically, beginning simply with the creation of points and lines, building out some useful and reusable abstractions, and eventually creating interesting structures and patterns, all with an eye to creating vector artwork for printing on pen […]

Some of our most popular programs are now available over on the website: https://www.programmingforpeople.com/shop Here is a good one! Using the python oAuth2 module to poll twitter for search data and start parsing the response into something meaningful. Based on some work that drove an interactive twitter wall at a networking event – watching for […]

Some of our most popular programs are now available over on the website: https://www.programmingforpeople.com/shop This is something that bugged me for a while when I started out in TD. How do you actually access external modules? Well here is your answer with example! We download, setup and install the speech_recognition module onto a mirror copy […]

Core Concepts Dictionaries – a structure and a concept A practical look at dictionaries in TouchDesigner Nested data structures – dictionaries in dictionaries Using Dictionaries as a preset structure Using Python to set parameters Using Python variables in scripts to generalize our code

Core Concepts Simple Logic constructs in Python and in TouchDesigner Scripting Logic and references Comparing values The Channel Class —– 25:23 Robert caught a small error on my part here. Line 25 should read: elif my_val1 ‘less than’ my_val3: (youtube won’t let me use actual brackets in a description) Thanks for the quick eyes Robert!
