TouchDesigner Tutorials, Operators and Interactive Projects

TouchDesigner is Derivative's node-based visual programming environment for real-time graphics, installations and live visuals. This hub collects everything Demos Lab publishes about it. It is built for artists, VJs, designers and creative coders who want to move from their first network to finished interactive work, with clear explanations of how the software actually thinks.

What you'll find here

Step-by-step tutorials

Guided walkthroughs take you from the interface and basic networks through Python scripting, instancing and performance tuning.

TOPs, CHOPs and SOPs

Plain-language breakdowns explain what each operator family does, how textures, channels and surfaces pass data between each other, and which operators to reach for first.

Interactive and audio-reactive builds

Project guides show how to drive visuals with sound, sensors, cameras and MIDI controllers for installations, live shows and gallery pieces.

Licensing explained

We compare the free Non-Commercial tier with the paid Educational, Commercial and Pro licenses so you know which one fits your project before you sell, exhibit or tour it.
