TouchDesigner

A node-based visual programming environment widely used for real-time fulldome content creation and live performances.

What is it?

TouchDesigner is a node-based visual programming platform developed by Derivative (Toronto, Canada). It enables real-time generation of 2D/3D visuals, audio-reactive graphics, interactive installations, and fulldome content β€” all without traditional coding.

Why Dome Artists Love It

  • Real-time β€” output fulldome visuals at 60 fps with no pre-rendering
  • Fisheye output β€” built-in domemaster and equirectangular camera modes
  • Audio-reactive β€” visuals respond to live audio input in real time
  • NDI/Spout support β€” stream to dome playback systems or LED controllers
  • Live performance β€” used extensively for VJ sets, concerts, and installations in domes

Common Workflows

TouchDesigner is particularly popular for Dome After Dark events, live music visualisations, and festival installations. It pairs well with tools like Resolume and Ableton Live for audio-visual performances. The NestDrop plugin for visualisation is also used alongside TouchDesigner at venues like Fort Worth.
